Description

BACKGROUND

[0002] Hydraulic cements, such as Portland cement, are used to form structural formations. Hydraulic cements can be mixed with aggregate to form mortars, which additionally include small aggregate and water, or concrete, which are mortars which additionally include large aggregate.

[0003] When working with hydraulic cements, it is desired to increase the slump and flow properties of the initially formed hydraulic cement composition to aid in placement of the composition and to extend the period of flowability in order to provide working time to finish the placement of the structure. Admixtures can be added to hydraulic cement that increase the slump and workability. Additionally, admixtures can be added that also reduce the amount of water required and to produce flowable cementitious compositions. The reduced water content increases the strength of the resulting hydraulic cement formation.

[0004] One admixture for increasing the flowability and reducing the water content is a polycarboxylate dispersant. Polycarboxylate dispersants are polymers with a carbon backbone with pendant side chains, wherein at least a portion of the side chains are attached to the backbone through a carboxyl group or an ether group. Polycarboxylate dispersants are very effective at dispersing and reducing the water content in hydraulic cements.

[0005] One drawback to polycarboxylate dispersants is that they have a tendency to entrain air in the cementitious composition during mixing. While some entrained air may be desired for particular applications, such as providing freeze-thaw durability to the cementitious composition, an excess of entrained air is detrimental to the compressive strength of the resulting hydraulic formation. Also, some insoluble defoamers, or contamination, can cause unpredictable air contents over time.

[0006] Generally in the construction industry, non-air entrained cementitious compositions having an air content of less than 3% is desired, with an air content of less than 2% being preferred. Air entraining admixtures are sometimes used to provide purposeful air contents of 5-8% which improves the freeze thaw durability of the cementitious mixture. When this is the case, it is desirable to be able to adjust the air content by changing the air entrainer dosage and to have the resulting air remain stable over time.

[0007] To overcome the excess entraining of air in cementitious compositions due to polycarboxylate dispersants, defoamers have been added to the cementitious mix to reduce the air content to a desired level. Defoamers typically have been included with the polycarboxylate admixture. However, the defoamers used in the prior art have been non-water-soluble compositions. Because the polycarboxylate dispersants are generally water soluble the problem with non-water-soluble defoamers is that they give an inadequate long term storage stability to the admixture. When a non-water-soluble defoamer is used in conjunction with a water soluble dispersant, the mixture separates over time. This requires that the mixture be mixed prior to use.

[0008] Another technique used in the prior art has been the grafting of the defoamer onto the dispersant molecule.

[0009] What is needed in the industry is an air controlling agent that can produce controllable air contents in non-air entrained and air entrained cementitious compositions in the presence of a dispersant for cementitious compositions.

SUMMARY

[0010] Water soluble air controlling agents can be mixed with a dispersant for cementitious compositions to provide an admixture for cementitious compositions that is stable over time. The water soluble air controlling agents are compatible with water based dispersants for cementitious compositions. The resulting compatible admixture has long term storage stability so that the admixture does not need to be mixed prior to use at the work site. The water soluble air controlling agent in the presence of a dispersant for cementitious compositions provides controllable air contents in non-air entrained and air entrained cementitious compositions.

[0011] An admixture for cementitious compositions is provided which comprises a water soluble air controlling agent and a dispersant for cementitious compositions.

[0012] A cementitious composition is provided which comprises cement, water, a water soluble air controlling agent, and a dispersant for cementitious compositions.

[0013] A method of making a cementitious composition is provided, wherein the method comprises mixing cement, water, a water soluble air controlling agent, and a dispersant for cementitious compositions.

The combination of a water soluble air controlling agent with a dispersant for cementitious compositions provides an admixture that is stable over time in that there is little or no phase separation between the dispersant and air controlling agent.

[0146] The amount of water soluble air controlling agent that is present in the admixture ranges from about 0.25 weight % to about 40 weight % based on the weight of the dispersant for cementitious compositions. Preferably, the amount of water soluble air controlling agent that is present in the admixture ranges from about 0.5 weight % to about 20 weight % based on the weight of the dispersant for cementitious compositions.

[0147] Examples of the water soluble air controlling agent include, but are not limited to, compounds of alkoxylated R, where R could be: a hydrocarbonpolyalkylene oxide, sorbitan, fatty acid, fatty alcohol, or C8-C22 alkyl amine. The hydrocarbon preferably contains from 1 to about 22 carbons, and the fatty acid and fatty alcohol preferably contain from about 8 to about 22 carbon atoms. Preferred alkoxylates are molecules containing ethylene oxide and/or propylene oxide. Most preferred alkoxylates are molecules containing ethylene oxide and propylene oxide. One group of these air controlling agent (ACA) materials are poly(alkylene oxides) where the alkylene group is derived from C2-18 groups and the polymer molecular weight is about 200 to about 25,000, preferably about 1,000 to about 7,500, with a hydrophobe content of at least about 25%, and preferably at least about 35%. The water soluble air controlling agents can be used in combination with other water soluble air controlling agents. Illustrative examples of these types of water soluble air controlling agents include, but are not limited to those set forth below.

[0148] Block copolymers of ethylene oxide (EO) and propylene oxide (PO), such as PLURONIC® products available from BASF, are examples of water soluble air controlling agents. Standard PLURONIC® products are EO-PO-EO based copolymers. PLURONIC® products with an R in the product name are PO-EO-PO based. The basic structures are given below: 20

[0149] Specific PLURONIC® product names are based on the EO and PO content and the molecular weight. The specific product name indicates the molecular weight of the hydrophobe, the propylene oxide, and the percent of the hydrophile, the ethylene oxide, in the molecule. The first two digits multiplied by 300 gives the hydrophobe molecular weight, and the last digit multiplied by 10 gives the percent hydrophile. For PLURONIC® R products, the numbers before the R multiplied by 100 gives the molecular weight of the combined PO blocks, and the number after the R multiplied by 10 gives the EO percentage. The solubility of the polymer is based on the hydrophile lipophile balance (HLB) value. Generally, as the HLB value increases the ability of the polymer to be solubilized by making micelles increases.

[0150] The SURFYNOL® 400 series of products are acetylenic diols. The last two digits of the product number indicate the percentage of ethylene oxide by weight. Some of the SURFYNOL® 400 series of products are water insoluble; however, SURFYNOL®465 and SURFYNOL®485 are water soluble. The basic structure of SURFYNOL® 400 series products is given by the following structure: 21

[0151] TERGITOL® NP, from Union Carbide Company, is a polymer of ethylene oxide and nonylphenol (ethoxylated nonylphenol) and is represented by the following structure: 22

[0152] JEFFOX® chemicals, from Huntsman Chemical Company, are mono alkyl polyoxyalkylenes. Preferred is a 50/50 ethylene oxide/propylene oxide random polymer with a mono-butyl terminal group[Bu—O—(PO)x(EO)x—H].

[0153] One measure of a product 's emulsification characteristics is the hydrophile lipophile balance (HLB). As the HLB increases, there are more hydrophilic groups in the surfactant and the more the surfactant is water soluble. Generally, an HLB of 3-6 indicates a water in oil emulsifier, an HLB of 7-9 indicates a wetting agent, an HLB of 8-18 indicates an oil in water emulsifier, an HLB of 13-15 indicates a detergent, and an HLB of 15-22 indicates a solubilizer. The following references provide more information about HLB: The Atlas HLB System, 4th printing, Wilmington, Del., Atlas Chemical Industries, 1963; “Emulsions”, Ullmans's Encyclopedia of Industrial Chemistry, 5th ed 1987; Fox, C., “Rationale for the Selection of Emulsifying Agents”, Cosmetics & Toiletries 101.11 (1986), 25-44; Graciaa, A., J. Lachaise, and G. Marion, “A Study of the Required Hydrophile-Lipophile Balance for Emulsification”, Langmuir 5 (1989):1215-1318; and Griffin, W. C. “Emulsions”, Kirk Othmer Encyclopedia of Chemical Technology, 3rd ed 1979.

[0154] Generally, materials with an HLB up to 4 have strong defoaming properties and little if any solubility. As the HLB value increases, the defoaming capabilities decrease and foaming capabilities increase. In the present invention, the air controlling agents generally have an HLB value ranging from about 5 to about 22.

[0155] The admixture of the present invention can be used in combination with any other admixture or additive for cement. Other cement admixtures and additives include, but are not limited to, set retarders, set accelerators, air-entraining or air detraining agents, corrosion inhibitors, any other dispersants for cement, pigments, wetting agents, water soluble polymers, strength enhancing agents, rheology modifying agents, water repellents, and any other admixture or additive that does not adversely affect the properties of the admixture of the present invention.

[0156] Other dispersants for cement include, but are not limited to, calcium lignosulfonates, beta naphthalene sulfonates, sulfonated melamine formaldehyde condensates, and any other chemical that functions as a dispersant or water reducer or superplasticizer for cement, and mixtures thereof.

[0157] Listed below are several examples of admixtures and additives that can be used with the present invention. U.S. Pat. No. 5,728,209 to Bury et al., which is incorporated herein by reference, contains a detailed description of different types of admixtures.

[0158] The term air entrainer includes any chemical that will entrain air in cementitious compositions. Air entrainers can also reduce the surface tension of a composition at low concentration. Air-entraining admixtures are used to purposely entrain microscopic air bubbles into concrete. Air-entrainment dramatically improves the durability of concrete exposed to moisture during cycles of freezing and thawing. In addition, entrained air greatly improves a concrete's resistance to surface scaling caused by chemical deicers. Air entrainment also increases the workability of fresh concrete while eliminating or reducing segregation and bleeding. Materials used to achieve these desired effects can be selected from salts of wood resin; (Vinsol resin); some synthetic detergents; salts of sulfonated lignin; salts of petroleum acids; salts of proteinaceous material; fatty and resinous acids and their salts; alkylbenzene sulfonates; and salts of sulfonated hydrocarbons. Air entrainers are added in an amount to yield a desired level of air in a cementitious composition. Generally, the amount of air entrainers in a cementitious composition ranges from about 0.2 to about 5.0 fluid ounces per hundred pounds of cement. But this can vary widely due to variations in materials, mix proportion, temperature, and mixing action.

[0159] Retarding, or delayed-setting, admixtures are used to retard, delay, or slow the rate of setting of concrete. They can be added to the concrete mix upon initial batching or sometime after the hydration process has begun. Retarders are used to offset the accelerating effect of hot weather on the setting of concrete, or delay the initial set of concrete or grout when difficult conditions of placement occur, or problems of delivery to the job site, or to allow time for special finishing processes or to aid in the reclamation of concrete left over at the end of the work day. Most retarders also act as water reducers and can also be used to entrain some air into concrete. The retarder used in the admixture of the present invention can include, but is not limited to an oxy-boron compound, lignin, a polyphosphonic acid, a carboxylic acid, a hydroxycarboxylic acid, polycarboxylic acid, fumaric, itaconic, malonic, borax, gluconic, and tartaric acid, lignosulfonates, ascorbic acid, isoascorbic acid, sulphonic acid-acrylic acid copolymer, and their corresponding salts, polyhydroxysilane, polyacrylamide, carbohydrates and mixtures thereof. Illustrative examples of retarders are set forth in U.S. Pat. Nos. 5,427,617 and 5,203,919, incorporated herein by reference. A further example of a retarder particularly suited for use in the present invention is a hydration control admixture sold under the trademark DELVO® by Master Builders Inc. of Cleveland, Ohio.

[0160] Air detrainers are used to decrease the air content in the mixture of concrete. Tributyl phosphate, dibutyl phthalate, octyl alcohol, water-insoluble esters of carbonic and boric acid, and silicones are some of the common materials that can be used to achieve this effect.

[0161] Alkali-reactivity reducers can reduce the alkali-aggregate reaction and limit the disruptive expansion forces in hardened concrete. Pozzolans (fly ash, silica fume), blast-furnace slag, salts of lithium and barium are especially effective.

[0162] Bonding admixtures are usually added to portland cement mixtures to increase the bond strength between old and new concrete and include organic materials such as rubber, polyvinyl chloride, polyvinyl acetate, acrylics, styrene butadiene copolymers, and other powdered polymers.

[0163] Water-reducing admixtures are used to reduce the amount of mixing water required to produce concrete of a certain slump, to reduce the ratio of water and cement, or to increase slump. Typically, water reducers will reduce the water content of the concrete mixture by approximately up to 15%.

[0164] Superplasticizers are high-range water reducers, or water-reducing admixtures. They are added to concrete to make high-slump, flowing concrete, and thus reduce the water-cement ratio. These admixtures produce large water reduction or great flowability without causing undue set retardation or entrainment of air in mortar or concrete. Among the materials that can be used as superplasticizers are sulfonated melamine formaldehyde condensates, sulfonated naphthalene formaldehyde condensates, certain organic acids, lignosulfonates, and/or blends thereof.

[0165] Natural and synthetic admixtures are used to color concrete for aesthetic and safety reasons. These coloring admixtures are usually composed of pigments and include carbon black, iron oxide, phthalocyanine, umber, chromium oxide, titanium oxide and cobalt blue.

[0166] Corrosion inhibitors in concrete serve to protect embedded reinforcing steel from corrosion. The high alkaline nature of the concrete causes a passive and noncorroding protective oxide film to form on the steel. However, carbonation or the presence of chloride ions from deicers or seawater can destroy or penetrate the film and result in corrosion. Corrosion-inhibiting admixtures chemically arrest this corrosion reaction. The materials most commonly used to inhibit corrosion are calcium nitrite, sodium nitrite, sodium benzoate, certain phosphates or fluorosilicates, fluoroaluminates, amines, organic based water repelling agents, and related chemicals.

[0167] Dampproofing admixtures reduce the permeability of concrete that have low cement contents, high water-cement ratios, or a deficiency of fines in the aggregate. These admixtures retard moisture penetration into dry concrete and include certain soaps, stearates, and petroleum products.

[0168] Grouting agents, such as air-entraining admixtures, accelerators, retarders, and non-shrink and workability agents, adjust grout properties to achieve a desired result for specific applications. For example, portland cement grouts are used for a variety of different purposes, each of which may require a different agent to stabilize foundations, set machine bases, fill cracks and joints in concrete work, cement oil wells, fill cores of masonry walls, and grout pre-stressing tendons and anchor bolts, and fill the voids in pre-placed aggregate concrete.

[0169] Gas formers, or gas-forming agents, are sometimes added to concrete and grout in very small quantities to cause a slight expansion prior to hardening. The amount of expansion is dependent upon the amount of gas-forming material used and the temperature of the fresh mixture. Aluminum powder, resin soap and vegetable or animal glue, saponin or hydrolyzed protein can be used as gas formers.

[0170] Permeability reducers are used to reduce the rate at which water under pressure is transmitted through concrete. Silica fume, fly ash, ground slag, natural pozzolans, water reducers, and latex can be employed to decrease the permeability of the concrete. Pozzolan is a siliceous or siliceous and aluminous material, which in itself possesses little or no cementitious value. However, in finely divided form and in the presence of moisture, pozzolan will chemically react with calcium hydroxide at ordinary temperatures to form compounds possessing cementitious properties.

[0171] Pumping aids are added to concrete mixes to improve pumpability. These admixtures thicken the fluid concrete, i.e., increase its viscosity, to reduce de-watering of the paste while it is under pressure from the pump. Among the materials used as pumping aids in concrete are organic and synthetic polymers, hydroxyethylcellulose (HEC) or HEC blended with dispersants, organic flocculents, organic emulsions of paraffin, coal tar, asphalt, acrylics, bentonite and pyrogenic silicas, natural pozzolans, fly ash and hydrated lime.

[0172] Bacteria and fungal growth on or in hardened concrete may be partially controlled through the use of fungicidal, germicidal, and insecticidal admixtures. The most effective materials for these purposes are polyhalogenated phenols, dialdrin emulsions, and copper compounds.

[0173] Fresh concrete can sometimes be harsh because of faulty mixture proportions or certain aggregate characteristics such as particle shape and improper grading. Under these conditions, entrained air which acts like a lubricant, can be used as a workability improving agent. Other workability agents are water reducers and certain finely divided admixtures.

[0174] Finely divided mineral admixtures are materials in powder or pulverized form added to concrete before or during the mixing process to improve or change some of the plastic or hardened properties of portland cement concrete. Portland cement, as used in the trade, means a hydraulic cement produced by pulverizing clinker, consisting essentially of hydraulic calcium silicates, all usually containing one or more of the forms of calcium sulfate as an interground addition with ASTM types, I, II, III, IV, or V. The finely divided mineral admixtures can be classified according to their chemical or physical properties as: cementitious materials; pozzolans; pozzolanic and cementitious materials; and nominally inert materials. Cementitious materials are materials that alone have hydraulic cementing properties, and set and harden in the presence of water. Included in cementitious materials are ground granulated blast-furnace slag, natural cement, hydraulic hydrated lime, and combinations of these and other materials. As discussed above, pozzolan is a siliceous or aluminosiliceous material that possesses little or no cementitious value but will, in the presence of water and in finely divided form, chemically react with the calcium hydroxide released by the hydration of portland cement to form materials with cementitious properties. Diatomaceous earth, opaline cherts, clays (including calcined clays), shales, fly ash, silica fume, volcanic tuffs and pumicites are some of the known pozzolans. Certain ground granulated blast-furnace slags and high calcium fly ashes possess both pozzolanic and cementitious properties. Natural pozzolan is a term of art used to define the pozzolans that occur in nature, such as volcanic tuffs, pumices, trasses, diatomaceous earths, opaline, cherts, and some shales. Nominally inert materials can also include finely divided raw quartz, dolomites, limestones, marble, granite, and others. Fly ash is defined in ASTM C-618.

[0175] In the construction field, many methods of strengthening concrete have been developed through the years. One modern method involves distributing fibers throughout a fresh concrete mixture. Upon hardening, this concrete is referred to as fiber-reinforced concrete. Fibers can be made of zirconium materials, steel, fiberglass, or synthetic materials, e.g., polypropylene, nylon, polyethylene, polyester, rayon, high-strength aramid, (i.e. KEVLAR®), or mixtures thereof.

[0176] A cementitious composition can be formed which comprises cement, water, and a water soluble air controlling agent and a dispersant for cementitious compositions. The cementitious composition can also include fine aggregates, coarse aggregates, pozzolans, air (either entrapped or purposefully entrained), clay, and pigments.

[0177] The fine aggregates are materials that pass through a Number 4 sieve (ASTM C125 and ASTM C33), such as natural or manufactured sand. The coarse aggregates are materials that are retained on a Number 4 sieve (ASTM C 125 and ASTM C33), such as silica, quartz, crushed round marble, glass spheres, granite, limestone, calcite, feldspar, alluvial sands, or any other durable aggregate, and mixtures thereof.

[0178] A method of controlling air in a cementitious composition is also provided which comprises mixing cement, water, a water soluble air controlling agent, and a dispersant for cementitious compositions.

[0179] The amount of water added to the cementitious composition is calculated based on a desired water to cement (W/C) ratio. The water to cement ratio typically ranges from about 0.2 to about 0.7 with the water and cement being measured by weight.

[0180] The air controlling agent can be added to a cementitious composition separately or it can be included with an admixture which is added to the cementitious composition, such as with the dispersant for cementitious compositions.

SPECIFIC EMBODIMENTS OF THE INVENTION

[0181] Samples of cementitious compositions were prepared using a polycarboxylate dispersant, comprising a polymeric carboxylate backbone with polyether side chains, and tested as detailed below.

[0182] The following tests were used: Slump (ASTM C143), Air content (ASTM C231), Set time (ASTM C403), % Flow (ASTM C-230). Aggregates met the specifications of ASTM C33. The term W/C refers to the water to cement ratio in a cementitious mixture. The term S/A refers to the sand to aggregate ratio by volume.

[0183] Air entraining agents used in the following examples were MB AE® 90 or MB VR® from Master Builders, Inc., Cleveland, Ohio.

EXAMPLE 1

[0185] Different polyoxyalkylene additives ranging in HLB from 1 to 19, listed below in Table 1, were tested in combination with a polycarboxylate dispersant. The reference dispersant was a polymeric carboxylate backbone with polyether side chains. The dispersant was added at 0.2 grams per hundred grams of cement. The amount of polyoxyalkylene additive was based on the active amount of dispersant added and was 1% for all mixtures.

[0186] The mortar mix contained 540 g of Medusa Type I cement, 1455 grams of sand, and 190 grams of water. The W/C ratio was 0.35. The results are listed below in Table 1.

[0187] The results shown in Table 1 demonstrate that materials with HLB values as high as 19 reduce air contents in cementitious mixtures containing polycarboxylate dispersants, and that materials with HLB values ≧5, which are beyond the range generally expected for defoamers, unexpectedly reduce air content in non-air entrained mixtures to acceptable levels. In addition, air contents do not significantly change with mix time and this produces predictable performance in practice.

EXAMPLE 2

[0188] Different polyoxyalkylenes ranging in HLB from 1 to 14, listed below in Table 2, were tested in combination with a polycarboxylate dispersant and an air entraining agent, MB VR®. The reference dispersant was a polymeric carboxylate backbone with polyether side chains. The dispersant was added at 0.2 grams per hundred grams of cement. The amount of polyoxyalkyelene was based on the active amount of dispersant added and was 1% for all mixtures. The air entrainer amount was present at about one fluid ounce per hundred weight of cement.

[0189] The mortar mix design contained 540 g of Medusa Type I cement, 1455 grams of sand, and 190 grams of water. The W/C ratio was 0.35. The results are listed below in Table 2.

[0190] Mix 2-1 shows high and stable air contents over time due to the polycarboxylate dispersant. Mix 2-2 shows that the combination of polycarboxylate dispersant and air entrainer produces even higher air contents that are stable over time. Mix 2-3 demonstrates unstable air contents over time in the presence of an air-entrainer and an insoluble, low HLB defoaming agent. The other mix results demonstrate that with higher HLB air controlling agents, stable and predictable air contents can be achieved with the combination of polycarboxylate dispersant and air entraining agent.

[0191] Examples 3, 4, and 5 contain the results for air controlling agents in non-air entrained concrete. Concrete mixture proportions for the examples shown in Table 3 contained 658 lb./yd3 cement content using a Type I portland cement, a sand:aggregate ratio (S/A) of 0.429 using limestone coarse aggregate, sand, and sufficient water to obtain a slump of 6″ to 8″. Concrete mixture proportions for the examples shown in Tables 4 and 5 contained a 600 lb./yd3 cement content using a Type I portland cement, a S/A of 0.433 using limestone coarse aggregate, sand, and sufficient water to obtain a slump of 6″ to 8″.

[0192] Examples 6 and 7 contain the results for air controlling agents in purposefully air-entrained concrete. Concrete mixture proportions contained a 600 lb./yd3 cement content using a Type I portland cement, a S/A ratio of 0.440 using limestone coarse aggregate, sand, and sufficient water to obtain a slump of 6″ to 8″.

EXAMPLE 3

[0193] Air controlling agents were tested at different levels in combination with a polycarboxylate dispersant. The reference dispersant was a polymeric carboxylate backbone with polyether side chains. The dispersant was added at 0.2 lbs. per hundred weight of cement. The types of air controlling agent tested were polyoxyalkylenes ranging in HLB from 1 to 12, PLURONIC® L-101, PLURONIC® L-61, PLURONIC® 17R2, and PLURONIC® L-43 from BASF, and a soluble alkyl aryl alkoxylate, TERGITOL® NP-6 from Union Carbide Company. The amount of air controlling agent was based on the active amount of dispersant added. The dispersant and the other air controlling agents were added with the sand, except 3-6 and 3-7, which were added with the water. The results are listed below in Table 3.

[0194] The results in Table 3 show that the polyoxyalkylene and alkyl aryl alkoxylate type air controlling agents can effectively lower the air content of a concrete mixture containing a polycarboxylate dispersant. Similar to the results found in Example 1, the soluble air controlling agents having an HLB≧5 were equally and unexpectedly as effective at lowering the air as traditional defoamers having an HLB≦4.

EXAMPLE 4

[0195] Air controlling agents were tested at different levels in combination with a polycarboxylate dispersant. The reference dispersant was a polymeric carboxylate backbone with polyether side chains. The dispersant was added at 0.2 lbs. per hundred weight of cement. The types of air controlling agent tested were polyoxyalkylenes ranging in HLB from 5 to 12 (PLURONIC® L-31, PLURONIC® 17R2, and PLURONIC® L-43 from BASF) and mono alkoxyalkoxylates (JEFFOX® WL-5000 and JEFFOX® WL-660 from Huntsman Chemical Co). Two insoluble defoamers, a polyoxyalkylene, PLURONIC® L-61 (HLB=3), and SURFYNOL® DF-75, (a non-silicone proprietary mixture) from Air Products and Chemicals, Inc., were included for comparison. The amount of air controlling agent stated was based on the active amount of dispersant added, and the dispersant and air controlling agent were added together with the water. The composition test results are listed below in Table 4.

[0196] Example 4 shows a comparison of air controlling agents and insoluble defoamers in non-air-entrained cementitious mixtures. Unexpectedly, the soluble air controlling agent/polycarboxylate admixtures (4-3,4-4, 4-7,4-8, 4-9,4-10, 4-11) performed as effectively as the known insoluble defoamer/dispersant combination. However, the soluble air controlling agent/polycarboxylate dispersant admixtures are more stable over time as compared to the insoluble defoamer mixtures.

EXAMPLE 5

[0197] Air controlling agents were tested at different levels in combination with a polycarboxylate dispersant. The reference dispersant was a polymeric carboxylate backbone with polyether side chains. The dispersant was added at 0.2 lbs. per hundred weight of cement. The type of air controlling agent tested was an ethoxylated acetylenic diol, SURFYNOL® 465, SURFYNOL® 440, compared to insoluble defoamers such as SURFYNOL® 420 from Air Products and Chemicals, Inc. The dispersant and air controlling agent or defoamer were added together with the water. The amount of air controlling agent or defoamer was based on the active amount of dispersant added. The SURFYNOL® 440 and 465 were stirred into the dispersant. The SURFYNOL® 420 was dispersed into the dispersant using a high shear propeller mixer operating at 1300 rpm for 2 minutes. The test results are listed below in Table 5.

[0198] Example 5 shows a comparison of acetylenic diol air controlling agents with various degrees of solubility. The insoluble defoamer and soluble air controlling agents performed similarly. Unexpectedly, the soluble air controlling agent/polycarboxylate admixtures (5-5,5-6, 5-7 and 5-8) performed as effectively as the known insoluble defoamer/dispersant combination. However, the soluble air controlling agent/polycarboxylate dispersant admixtures are more stable over time as compared to the insoluble defoamer mixtures.

[0199] The results in Tables 3, 4, and 5 demonstrate that any number of soluble polyoxyalkylenes, mono alkyl polyoxyalkylenes, or alkyl aryl alkoxylates may be used to control air contents of non-air entrained concrete mixtures containing a polycarboxylate dispersant.

EXAMPLES 6-1 THROUGH 6-6

[0200] Cement mixes were prepared that varied the amount of an insoluble polyoxyalkylene defoamer (HLB=3), PLURONIC® L-61, and the amount and type of an air entraining agent. The air entraining agents were proprietary mixtures MB VR® or MB AE® 90 from Master Builders, Inc. The air entrainer amounts are listed as fluid ounces per hundred weight of cement. All samples contained a dispersant, which comprised a polymeric carboxylate backbone with polyether side chains. The dispersant was added at 0.2 lbs. per hundred weight of cement. The amount of defoamer was based on the active amount of dispersant added. The dispersant and defoamer were added together with the water, and the air entraining agent was added with the sand. The test results are listed below in Table 6.

[0201] Examples 6-1 to 6-6 show the performance of a defoamer that demonstrates desired performance characteristics in air-entrained concrete; however, it is insoluble. The mixtures had typical dosages of air-entraining agents, which were stable over time.

EXAMPLES 6-7 TO 6-12

[0202] Concrete mixes were prepared that varied the amount of soluble polyoxyalkylene (HLB=5) air controlling agent, PLURONIC® L-31, the amount of air entraining agent, MB AE® 90, and the amount of dispersant. The air entrainer amount is listed as fluid ounces per hundred weight of cement. The dispersant was a polymeric carboxylate backbone with polyether side chains. The amount of air controlling agent was based on the active amount of dispersant added. The dispersant and air controlling agent were added together with the water and the air entraining agent was added with the sand, except for Mix 6-12, which had the air entrainer added first, then the dispersant and air controlling agent added two minutes later. The test results are listed below in Table 6.

EXAMPLES 6-13 TO 6-17

[0203] Concrete mixes were prepared with the same air controlling agent as in examples 6-7 to 6-12 and a lower dosage of air entraining agent, MB AE® 90, and a varied amount of dispersant. A second air entrainer, MB VR®, was included for comparison. The air entrainer amounts are listed as fluid ounces per hundred weight of cement. The dispersant was a polymeric carboxylate backbone with polyether side chains. The amount of air controlling agent was based on the active amount of dispersant added. The dispersant and air controlling agent were added together with the water and the air entraining agent was added with the sand. The test results are listed below in Table 6.

EXAMPLES 6-18 TO 6-23

[0204] Concrete mixes were prepared that varied the amount of soluble polyoxyalkylene air controlling agent (HLB=12), PLURONIC® L-43, and the amount of an air entraining agent, MB AE® 90. The air entrainer amount is listed as fluid ounces per hundred weight of cement. All samples contained a dispersant, which was a polymeric carboxylate backbone with polyether side chains. The dispersant was added at 0.2 lbs. per hundred weight of cement. The amount of air controlling agent was based on the active amount of dispersant added. The dispersant and air controlling agent were added together with the water. The air entraining agent was added with the sand. The test results are listed below in Table 6.

EXAMPLES 6-24 TO 6-28

[0205] Concrete mixes were prepared that varied the amount of soluble polyoxyalkylene air controlling agent (HLB=7), PLURONIC® 17R2, and the amount of an air entraining agent, MB AE® 90. The air entrainer amount is listed as fluid ounces per hundred weight of cement. All samples contained a dispersant, which was a polymeric carboxylate backbone with polyether side chains. The dispersant was added at 0.2 lbs. per hundred weight of cement. The amount of air controlling agent was based on the active amount of dispersant added. The dispersant and air controlling agent were added together with the water and the air entraining agent was added with the sand. The test results are listed below in Table 6.

EXAMPLES 6-29 TO 6-32

[0206] Concrete mixes were prepared that varied the amount of soluble polyoxyalkylene air controlling agent (HLB=15), PLURONIC® L-64, and the amount of air entraining agent, MB AE® 90, and the amount of dispersant. The air entrainer amount is listed as fluid ounces per hundred weight of cement. The dispersant was a polymeric carboxylate backbone with polyether side chains. The amount of air controlling agent was based on the active amount of dispersant added. The dispersant and air controlling agent were added together with the water and the air entraining agent was added with the sand. The test results are listed below in Table 6.

[0207] Table 6 shows the results of water soluble polyoxyalkylene air controlling agents (6-7 to 6-32) compared to an insoluble polyoxyalkylene defoamer. Examples 6-1 through 6-6 pertain to the insoluble polyoxyalkylene reference and show controlled and predictable air contents over time. Examples 6-7 through 6-12 show that a soluble air controlling agent can provide similarly predictable air contents over time. Examples 6-13 through 6-17 demonstrate that air contents can be adjusted by changing the dosage of the air entraining agent. Examples 6-18 through 6-23, 6-24 through 6-28, and 6-29 through 6-32 demonstrate that as the solubility (HLB) increases, that similar and predictable air contents can be obtained by increasing the percentage of the air controlling agent in the polycarboxylate dispersant, adjusting the air entraining agent dosage, or both.

EXAMPLE 7

[0208] Concrete mixes were prepared that varied the amount of SURFYNOL® 440 and SURFYNOL®465, the amount of air entraining agent, MB AE® 90, and the amount of dispersant. The air entrainer amount is listed as fluid ounces per hundred weight of cement, and the dispersant was added as percent by weight of cement. The dispersant was a polymeric carboxylate backbone with polyether side chains. The amount of air controlling agent was based on the active amount of dispersant added. The dispersant and air controlling agent were added together with the water and the air entraining agent was added with the sand. The test results are listed below in Table 7.

[0209] Table 7 shows that predictable air contents were obtained with the various levels of dispersant and soluble, ethoxylated acetylenic diol air controlling agent, which was similar to the reference of the same chemistry.

EXAMPLE 8

[0210] Concrete mixtures were prepared at a ready mix plant to confirm the effectiveness of a water soluble air controlling agent in practice under field conditions, such as truck mixing. Mixes 8-1 and 8-3 represent a soluble air controlling agent (HLB=5), PLURONIC® L-31. Mix 8-2 represents an insoluble defoamer (HLB=3), PLURONIC® L-61. Mix 8-4 represents the non-silicone proprietary mixture as in Example 4-12, SURFYNOL® DF-75.

[0211] The air controlling agent and reference defoamers were tested in combination with a polycarboxylate dispersant and an air entraining agent, MB AE® 90. The reference dispersant was a polymeric carboxylate backbone with polyether side chains. The dispersant amount is listed as % per hundred weight of cement. The amount of air controlling agent was based on the active amount of dispersant added. The air entrainer amount is listed as fluid ounces per hundred weight of cement. The concrete mix proportions are listed in Table 8 below. For examples 8-1 and 8-2, the dispersant and air controlling agent or reference defoamer combination was added to a concrete mix having a 2-3.5″ slump. Examples 8-3 and 8-4 had the combination added immediately after batching all of the ingredients.

[0212] The results shown in Table 8 demonstrate that the water soluble air controlling agent is effective under field conditions, and that it provided predictable air contents that were maintained over a 60 minute time frame. A similar air content response was observed for the soluble air controlling agent and insoluble defoamer when used with a dispersant level of 0.08%. The non-silicone proprietary mixture reference was found to have high and unpredictable air contents over time.

EXAMPLE 9

[0213] The mortar mixtures contained 540 g of Ashgrove Type I cement, 1,455 g of standard graded lab sand (ASTM C-109) and 250 g of water. The polycarboxylate (PC) dispersant was added at 0.2 g per hundred grams of cement and the additive was 1% based on active dispersant for all mixes.

[0214] Included in this example are high molecular weight poly(alkylene oxides) having molecular weights within the range of 100,000 to 8,000,000. Specifically, the materials tested in this example were poly(ethylene oxides) having molecular weights of 100,000 and 4,000,000. Also included in this example were two low molecular weight ethylene oxide (EO) and propylene oxide (PO)—EO/PO type polymers L31 with a molecular weight of 1,100 and hydrophobe content (PO) of 90% and 17R2 with a molecular weight 2,150 and hydrophobe content of 80%. Another EO/PO type polymer was tested that had a low hydrophobe content of 20% and a molecular weight of 11,400 (F88).

[0215] Results of the testing show the ability of all the ACA 's of the present invention to lower air content, with the lowest demonstrating a 50% reduction in air content (TERGITOL and SURFYNOL) as compared with the PEG 's. Specifically, the results show that the poly(alkylene oxides) in the present invention, as described above, are effective in controlling air contents—6.3 and 7.1. This is in contrast to the high molecular weight poly(ethylene oxides) which were found to have little air controlling effectiveness 20.5 to 21.5 air content. Additionally, the F88 material which contains a hydrophobe content of 20%, demonstrates that a hydrophobe content of about 25% or less is not as effective in providing air control.
