First, the use of the two is different:
1. The use of AAC masonry: It is an excellent new type of building material that is widely used. It is widely used in buildings, such as Shanghai International Hotel, Shanghai Tower, Fuzhou Building, People's Bank of China Building and other high-rise buildings.
2. The use of ordinary air-entrained blocks: it can be made into wall blocks, thermal insulation blocks, pressure panels, floor slabs, wall panels and thermal insulation pipes and other products. Air-entrained blocks have been widely used in industrial and civil buildings in my country. In load-bearing structures and pipeline insulation, it has become an important part of new building materials.
Second, the characteristics of the two are different:
1. Features of AAC masonry: lightweight and porous, thermal insulation, good fire resistance, nailable, sawn, planed and has a certain earthquake resistance.
2. The characteristics of ordinary aerated blocks: good thermal insulation performance, low thermal conductivity; strong compressive capacity of aerated blocks; light bulk density, which can reduce the weight and cost of the building, and is conducive to improving the earthquake resistance of the building. When the temperature is below 600 ℃, the compressive strength of aerated concrete increases slightly. When the temperature is about 600 ℃, its compressive strength is close to the compressive strength at room temperature, so the fire protection of aerated concrete as a building material The performance reaches the national first-class fire protection standard.
