Autoclaved Aerated Concrete (AAC) is a light weight, multi-cell new construction material; the features include lower density, heat insulation, processibility, fire and acoustical resistant properties.
 

AAC 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. It is made into the multi-cell silicate product by the processes of molding, pre-curing, cutting, evaporating and curing.
With abundant air cells and micro apertures inside the aerated brick, it has good performance of heat insulation and preservation. In addition, the

most prominent advantage is its plasticity. Due to the lightness and the lower hardness, AAC units are available in numerous shapes and sizes according to practical construction applications.
