1.What is the AAC ?
Autoclaved Aerated Concrete (AAC) is a siliceous material (sand, fly ash,gangue etc.) and calcareous materials (lime, cement) as the main raw material, mixing with foaming agent(aluminum powder) by mixing, casting, pre-curing, cutting, autoclave process made of light weight concrete products..
As a result of its excellent properties, AAC is used in many building constructions.
2.The advantage of the AAC
1.Lightweight: The aerated concrete dry bulk density generally is 400-800kg/m3, equivalently to clay brick 1/3, normal concrete 1/5, lower than normal light-weight aggregate concrete and hollow brick, hollow clay brick.
2.Fireproof:
Most of the major raw materials is inorganic materials, so it has good fire resistance, and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 90mm walls can reach to 245 minutes fire resistance, 300mm thick up wall can reach to 520 minutes fire resistance.
3.Sound insulation:
Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 10mm thick wall up to 41 db.
4.Green:
Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.
5.Economies:
An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
