New methods are currently being actively used for housing construction. Compact, durable, and aesthetic houses can be quickly built on vacant land using prefabricated assembly, while significantly saving costs. This technology does not require bricks or cement; instead, it uses a frame assembled from bison boards, aerocon panels, steel profiles, and iron pipes.
Materials for Walls and Partitions
Aerocon panels are used for building walls, and bison boards are used for creating partitions and ceilings. An aerocon panel is a sandwich panel made from a mixture of cement and silicate. It has a thick layer of cement-fiberboard on both sides. To make it soundproof, heatproof, waterproof, and fireproof, a mixture of gypsum and chemicals is introduced between the layers, which turns out to be stronger than concrete filling. Thanks to this chemical composition, bubbles form inside the panel, allowing it to regulate temperature. The cement-fiberboard prevents mold and termite damage to wood.
Bison Board and House Construction
Bison board is a waterproof and fireproof cement-wood fiber sheet made from a mixture of cement and sawdust. It is used to create partitions, suspended ceilings, flooring, and internal ceilings. The cost of one such sheet ranges from 25 to 80 rupees per square foot, depending on its thickness, length, and width.
The entire frame of the prefabricated house is formed using aerocon panels and bison boards. These boards are 10 feet long and 2 feet wide, although they are available in various sizes. These panels have grooves that allow them to connect easily with each other, thereby increasing the overall strength of the structure. The entire volume of the building is assembled from these boards and metal pipes. The roof is also made from these same boards. After that, interior work is carried out in the standard way, whether it is laying tile floors or wooden elements in the walls.
Economic Benefit and Application
By constructing in this manner, the use of cement, gravel, and water is completely eliminated. Construction using these panels or boards proves to be much more economical. The cost of building a house using this technology can be 30 percent lower than with traditional methods. This technology has been used in Kerala and other southern states of India for about ten years.
