The advantage of aerated concrete blocks for high-rise buildings

Aerated concrete is porous silicate concrete, with siliceous material and calcium material as the main raw material, aerated agent mixed, mixed with water, pore formed by chemical reaction, after casting molding, pre-curing cutting, autoclaved curing and other processes, the advantages of aerated concrete block used in high-rise buildings are described below:
1, Light weight
Aerated concrete dry bulk density is generally 400-700 kg/m3, compared to about one-third of the clay brick, 1/5 of the normal concrete, and lower than the general light aggregate concrete and hollow block,
Therefore, the adoption of aerated concrete as wall material can greatly reduce the weight of the building, and then can reduce the size of the building foundation and beam, column structure, saving construction materials and engineering costs, but also can improve the seismic capacity of the building.
2, good insulation performance
Aerated concrete interior has a large number of tiny pores, thus has good heat preservation and heat insulation performance, the coefficient of thermal conductivity of aerated concrete are usually as follows: 0.09-0.22 w /, was only about a quarter of the clay brick - 1/5, 1/5-1/10 of ordinary concrete, 
Compared with the general clay brick wall with a thickness of 49cm, the thermal insulation effect of the aerated concrete wall with a thickness of 20cm can not only save the energy of heating and cooling, but also greatly improve the plane utilization coefficient of the building.
Aerated concrete without coarse aggregate, with good machinability, can be saw, planer, drill, nail, and can be used appropriate bond materials bond, to provide favorable conditions for construction.
4,Wide source of raw materials, high production efficiency and low production energy consumption
Aerated concrete can be produced with sand, slag, fly ash, tailings, coal gangue and quicklime, cement and other raw materials,Aerated concrete can make great use of industrial waste residue.It has high production efficiency and low energy consumption, and its energy consumption per unit product is only 50% higher than that of clay brick of the same volume.
