Feasibility report on aerated concrete production process line

NEWS

A new type of lightweight thermal insulation building material, which is made of silica materials (such as sand, fly ash, etc.) and calcareous materials (lime and cement), through the process of proportioning pouring, gas expansion, cutting and curing, has been produced and applied for more than 60 years in China. Because of its light weight and good thermal insulation performance, it has been used as a building material. Widely used in industrial and civil buildings, it is the most mature new wall material in production technology and application technology.


Aerated concrete block has more positive significance for environmental protection and saving land resources because it uses fly ash as the main raw material. The thermal conductivity of the product is low (about 0.09-0.17w/m.k), which is 1/4 of clay brick. Therefore, it is an energy-saving building material with good thermal insulation performance. Therefore, the development of fly ash aerated concrete as a green building material is in line with the sustainable development strategy.


Aerated concrete is light in weight. It is 300 kg/m3-800kg/m3 in different grades, only about 1/3 of clay brick. It can simplify foundation, improve seismic resistance and reduce building self-weight for high-rise buildings in areas with low ground endurance. Because of its good thermal insulation performance, it can save energy consumption of heating and refrigeration. With the same thermal insulation effect as clay brick, it can greatly reduce wall thickness, save material consumption, reduce construction investment, and increase the use area of buildings. Because of the light weight and large block shape of aerated concrete block, it can improve construction and transportation efficiency, shorten construction cycle and reduce project cost.
