High Precision AAC (Autoclaved Aerated Concrete)

Autoclaved Aerated Concrete (AAC) is a siliceous material (sand, fly ash and silicon tailings such as waste porcelain clay, stone processing waste materials, blast furnace slag, etc.) and calcareous materials (lime, cement) as the main raw material, mixing fat gas agent (aluminum powder), by ingredients, mixing, casting, pre-curing, cutting, autoclave, curing process made of light porous silicate products, because by the hair contains a lot of gas even after the small pores, hence the name of aerated concrete

Advantages of AAC Block:

 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. so, using aerated concrete as wall material can

 lighten the building self weight, and then reduce the size of building foundation, girder and pillar etc. Structure,

 save building material and project cost, improve the building shock resistance.

Several common building material volume density (kg/m3)

    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, Insulation: As the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties. The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.

    5, Permeability: Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly paste tiles.

    6, Anti-seismic:The same building structure, improve the two seismic than the brick level.

    7, Green: Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building materia
