- 9. A process for entraining air in a hydraulic cement mix, which includes hydraulic cement, aggregate, and sufficient water to effect hydraulic setting of the cement, comprising the addition of an additive consisting essentially of coconut acid diethanolamide, produced by reacting alkyl ester of coconut acid with diethanolamine, said additive being in an effective amount of between 0.0016% and 0.0084% and a capramide diethanolamine in an effective amount of between 0.0016% and 0.0084% by weight based upon the weight of the cement, whereby air will be entrained in said mix in an amount of 3% to 9% by volume of said mix.
- 10. A process for entraining air in a hydraulic cement mix in accordance with claim 9, wherein said hydraulic cement comprises portland cement.
- 11. A process for entraining air in a hydraulic cement mix in accordance with claim 9, wherein said aggregate is present in an amount of up to 80% by weight, based upon the total weight of the hydraulic cement mix.
- 12. A process for entraining air in a hydraulic cement mix in accordance with claim 9, wherein said coconut acid is comprised as follows:
- ______________________________________Lauric Acid 46-58%Myristic Acid 15-23%Palmitic Acid 8-14%Stearic and Oleic Acid 7-24%______________________________________
- 13. A process for entraining air in a hydraulic cement mix in accordance with claim 9, wherein said coconut acid diethanolamide reaction product comprises:
- ______________________________________Coconut Acid Diethanolamide 85-90%Coconut Acid Alkyl 0-10%Coconut Acid 0-0.5%Diethanol Amine 0-5%______________________________________
- 14. A process for entraining air in a hydraulic cement mix in accordance with claim 9, wherein said reaction is conducted with equal moles of coconut alkyl ester and diethanolamine.
- 15. A process for entraining air in a hydraulic cement mix in accordance with claim 9, wherein said capramide diethanolamine comprises:
- ______________________________________Octanoic Acid C.sub.8 0.5-1.5%Capric Acid C.sub.10 94-98%Lauric Acid C.sub.12 1.5-2.5%______________________________________
- 16. A product made in accordance with the process of claim 9.
