Contact SupplierWe offer aac is autoclaved aerated concrete. The blocks are made to aerate by creating a reaction between silica in base material such as fly ash or active lime, and aluminum power. The block hardness is being achieved by cement strength, and instant curing mechanism by autoclaving. Gypsum acts as a long term strength gainer.
aac blocks plant is becoming more and more popular around the world, from western countries and then to developing countries. Below properties make aac have unmatchable property, especially for high buildings:
1) extreme light weight
2) large variety of sizes
3) high fire resistant
4) excellent thermal insulation
5) great sound insulation
main ingredients include fly ash, water, quicklime, cement, aluminum powder and gypsum. The block hardness is being achieved by cement strength, and instant curing mechanism by autoclaving. Gypsum acts as a long term strength gainer. The chemical reaction due to the aluminum paste provides aac its distinct porous structure, lightness, and insulation properties, completely different compared to other lightweight concrete materials. The finished product is a 2.5 times lighter block compared to conventional bricks, while providing the similar strengths. The specific gravity stays around 0.6 to 0.65. This is one single most usp of the aac blocks, because by using these blocks in structural buildings, the builder saves around 30 to 35 % of structural steel, and concrete, as these blocks reduce the dead load on the building significantly.
The current prices of fly ash blocks are in the same range of cement blocks & traditional bricks. But comparatively fly ash blocks are having more strength, fire resistance, earthquake resistance, light weight, lesser brakeage and saves structural cost by 40%.
