AAC Block making plant (Autoclaved aerated concrete plant) is a highly Thermal insulation thermally insulating concrete-based material used for both internal and external construction.

Autoclaved aerated concrete is cured in an autoclave - a large pressure vessel. Besides AAC's insulating capability, one of its advantages in construction is its quick and easy installation.

The autoclaved aerated concrete production process different slightly between individual production plants but the principles are similar. We will assume a mix that contains cement, lime and sand; these are mixed to form slurry. Also present in the slurry is fine aluminum powder - this is added to produce the cellular structure. The density of the final block can be varied by changing the amount of aluminum powder in the mix.
