2. Description of the Related Art
Since ancient times, gypsum has been one of the basic materials used in a building construction. A Plaster is made from baking and grinding the gypsum. The Gypsum is a member of the calcium containing construction materials abundantly found in nature and is available in almost all parts of the earth. It ranks fifth in terms of natural occurrence. The Calcium sulfate occurs in two forms in nature.
Gypsum or hydrated calcium sulfate, with the chemical formula CaSo4.2H2O, occurs in nature in the form of spear-shaped crystals, filaments, finely-grained masses (alabaster). Gypsum belongs to the monoclinic crystal system and has a specific gravity of 2.32 and a hardness of 2. Gypsum has low relief and weak birefringence.
Anhydrite or anhydrous calcium sulfate, with the chemical formula CaSO4, is orthorhombic and has a specific gravity of 2.89˜2.98 and a hardness of 3˜3.35. The Anhydrite or anhydrous calcium sulfate has a moderate birefringence and a higher relief.
During the past recent years, blocks of plaster have been manufactured and marketed as a type of prefabricated walls, for serving such purposes as constructing walls and partitions. However, they have not been widely used due to their high weight and non-resistance to earthquake or similar events.
The large-scale and growing need for housing and buildings has made it essential to employ modern methods and materials with the aim of speeding up construction, reducing weight of buildings, increasing life expectancy and strengthening buildings against earthquake more than ever before. The problems such as the longer periods of construction, a short life expectancy, and a high cost of construction require a proper solution such as the scientific use of modern methods and modern building materials to reduce a weight of building and building material, reduce a construction time, enhance the durability of building and building material, and ultimately reduce the construction costs.
Reducing a building weight is one of the modern issues in the construction science and industry and is expanding and advancing day by day. This technology involves the reduction of the final weight of a building by means of employing modern techniques, using new construction materials, optimizing construction methods, and reducing the building weight thereby not only saving costs, time and energy, but also mitigating the damages arising from the natural disasters such as earthquake and minimizes the damages arising largely from the weight of the building. To employ weight reduction (lightening) techniques, the reasons behind the heaviness of buildings, must be properly addressed at first. Once these reasons are identified, efforts should be made to either eliminate or minimize their effect on the final weight of the building.
The lesser the weight of the structure, the lesser the energy absorbed from earthquakes, and thus the seismic effect of the earthquake to the building is reduced. In other words, reducing a weight of (lightening) a building means providing a more safety against earthquakes.
The use of traditional and old construction materials such as bricks not only adds to the magnitude of the dead load of a building but also increases an energy consumption thereby practically wasting energy. Moreover, a low erection speed and a high volume of building rubble arising from the use of such materials are among the other problems arising with the use of such traditional materials.
On the other hand, as the weight of a building increases, the cost price of the building structure also increases thereby ultimately leading to a rise in the cost price of the building. These issues can be considered as part of the numerous problems faced by this market.
One of the prior arts provides a gypsum based panel such as plasterboard. The panels are manufactured by mounting the rigid board materials onto a frame and applying the facing material to the board with a bonding agent. The cited prior art disclosed herein fails to increase the speed of building production. Also, the cost price of constructing the buildings is high.
However, with the use of the present day prior art panels, the cost price for constructing the buildings are high. Also, the structural and building weights are high.

Further, there is a need for a prefabricated panel that controls an energy consumption in the buildings and reduces its wastage. Still further, there is a need for a panel that increases a speed of constructing the internal walls, lateral walls and corner walls in the buildings and thereby reducing a cost price of a construction.

According to an embodiment herein, a mineral composite panel or block is a product which has been designed and produced in full conformity to the climatic conditions of the dry and semi-humid geographic regions. In this type of mineral composite panel, the weak properties of the base materials such as a fracture, a weakness toward moisture, and a low compressive resistance and a bending strength are modified. To achieve this end, carbonate and clay-based compounds as well as an internal mesh are added to the compressive and bending strengths of the original compounds as a result of which the weight of the composite mineral panel is reduced greatly and the compressive and bending strengths of the composite mineral panel is enhanced to a great extent. The acoustic coefficient of the composite mineral panel is quite high and provides good noise and thermal insulation.
Furthermore, the composite mineral panel of the embodiments herein provides other excellent features such as a low weight, a high bending and compressive strengths, use of fibers and internal meshing. The composite mineral panel of the embodiments herein, does in no way lead to a collapse or physical injuries in times of earthquakes. The prefabricated mineral composite panels are fabricated at very reasonable prices compared to other construction materials and provide very high erection speed. In case the use of such prefabricated mineral composite panels forms the basis of structural design from the very beginning of the implementation of a project, the weight of a building can be reduced to great extent, and in turn allowing considerable savings on steel and concrete.
The prefabricated mineral composite panels of the embodiments herein is formed with a mixture comprising the Polypropylene plastic mesh or fiber-glass mesh, the slender polypropylene or fiber-glass fibers up to 30 mm or 20 cm, an industrial alpha gypsum, an industrial beta gypsum, calcium carbonate, sodium bentonite, perlite, salt, reinforcing resin, waterproofing resin and water.
As soon as the mesh is placed in the cast and tied up, the cast is ready for the mixture of composite materials to be poured into the cast. The entire mineral raw materials are mixed together in a dry form at the relevant mixing ratios, and then water is added in proportion to its weight and mixed for a specific period of time as indicated in the production instructions. Then, a dough-like mixture is then poured into the cast and flattened on top. After a specified period of time, the product is removed from the cast and is left free on the pallets in the workshop space so that the mineral composite panel is made to sets-in completely.
Finally, the mineral composite panel is transferred to the drying (baking) furnace so that the composite panel is dehydrated and becomes completely dry after the required time. Once removed from the drier, the mineral composite panel is ready to be forwarded to the construction sites for erection purposes.
These mineral composite panels are erected as follows: A number of punched galvanized iron angles, having the dimensions of 5×5 cm, is fitted on the ceiling (where the wall is going to be erected), and the panels are placed against them. Then, a number of angles is fitted in front of it to ensure it stands in place. The panels are connected to one another by means of a special mineral adhesive. To provide the required hydridation between the panels and the special adhesive, the lightweight mineral composite panel of 8 cm or 12 cm is wetted with water prior to adhesive application and installation. Then, adhesive is applied and spread evenly. The next panel (after wetting) is placed exactly beside the first one, and this procedure is continued until the whole wall is completed.
The mineral composite panel is completely waterproof and is resistant to impact, heat and cold. The mineral composite panel is highly lightweight and reduces structural and building weights. The mineral composite panel allows an energy control and efficiency in buildings and reduces energy wastage. The use of mineral composite panel speeds up building construction works. The mineral composite panel enhances the safety of building walls against fire and earthquake. The mineral composite panel increases the acoustic and thermal resistance factors in the building walls.
To better evaluate mineral composite panels, the maximum bending stress on the x axis of the panels (the weakest direction) is calculated by the two types of concentrated and distributed loads.
The Bending formula:
Where M is the bending moment which causes bending stress,
I is the moment of inertia of the section under stress
σb is the bending stress
E is the distance to the neutral axis
Y is the Young's modulus
R is the radius of the curvature of the member upon bending
Given our need for force, only the first two fractions are used to solve the equation.
