When customers planned to invest AAC plant, did not learn very well for fly ash brick manufacturing process equipments. After learning and reference the same range company, forming the concept of steam curing brick equipment. Such as steam curing brick, AAC bricks needs to high temperature and pressure curing, with autoclave and boiler. Boiler applies to supply steam gas to autoclave.

The standard or blind hole brick with press brick machine, were stacked and transported into autoclave to high temperature and pressure curing.
    The reaction process :
CaO+H2O—Ca(OH)2+15.5 Kcal(Mix YouTi bentonite)
Ca(OH) 2+ SiO2+(n-1)H2O   174.5℃ Saturated steam
CaO*SiO2 * nH2O(Calcium silicate)
This bricks apply to bear high pressure wall of multilayer mixed structure construction

This kinds of blocks apply to non-bear high pressure of high layers mixture construction, used to  wall filling materials.
3、Cement bricks

Cement bricks with steam curing is not many, as usually, cement bricks can up to requirements after natural dry. If the customers have a large quantity need, and want to reduce curing cycle, can adopt this kinds of steam curing way.
