synonym Aerator block Generally refers to aerated concrete block

Aerated concrete block is a new type of building material with light weight, porous, heat insulation, good fire resistance, nailing, sawing, planing and certain seismic capacity. As early as the early 1930s, China began to produce such products and widely used them. For example: Shanghai International Hotel, Shanghai Building, Fuzhou Building, People's Bank of China Building and other high-rise buildings. It is an excellent new building material and has the advantages of environmental protection.

Product benefits

Light weight

Aerator block

The general mass of aerated concrete block is 500-700 kg/m3, which is only 1/4-1/3 of clay brick and lime sand brick, and 1/5 of ordinary concrete. It is a lighter type of concrete, and is suitable for infill walls of high-rise buildings and load-bearing walls of low rise buildings. Using this material, the deadweight of the whole building can be reduced by more than 40% compared with that of ordinary brick concrete structure buildings. Since the deadweight of the building is reduced and the seismic damage is small, the seismic capacity of the building is greatly improved.

Thermal insulation

The thermal conductivity of aerated concrete is generally 0.11-0.18W/m · K, which is only 1/4-1/5 of that of granular soil brick and lime sand brick (the thermal conductivity of granular soil brick is 0.4-0.58W/m · K; the thermal conductivity of lime sand brick is 0.528W/m · K), which is about 1/6 of that of ordinary concrete. Practice has proved that the thermal insulation effect of 20 cm thick aerated concrete wall is equivalent to that of 49 cm thick clay brick wall, and its thermal insulation performance is also much better than that of 24 cm thick brick wall. This greatly reduces the thickness of the wall, correspondingly expands the effective use area of the building, saves the thickness of building materials, improves the construction efficiency, reduces the project cost, and reduces the self weight of the building.
