Autoclaved Aerated Concrete Production Line

Introduction of Autoclaved Aerated Concrete (AAC)
With the obvious advantage of light weight, this Autoclaved Aerated Concrete (AAC) is a multi-cell new construction and building material, which is made from silicon material (silica sand, or recycled fly ash) and calcium material (lime, cement), mixing with foaming additive (aluminum powder), batching with water, the reaction between aluminum and concrete causes microscopic hydrogen bubbles to form, expanding the concrete to about five times its original volume. Through the processes of molding, pre-curing, cutting, evaporating and curing, this building material is then made into the multi-cell silicate product.

Features of Autoclaved Aerated Concrete( AAC)
•Lower density
•Good heat insulation and preservation
•High processibility
•Fire and acoustical resistant properties
•Most prominent advantage: plasticity
