Autoclaved Concrete Top

May 01, 2020· Autoclaved Concrete. Autoclaved aerated concrete (AAC), a form of cellular concrete, is a low-density cementitious product of calcium silicate hydrates in which the low density is obtained by the formation of macroscopic air bubbles, mainly by chemical reactions within the mass during the liquid or plastic phase.

Autoclaving concrete masonry| Concrete Construction Magazi

What is autoclaving? Why are some concrete masonry units autoclaved units whereas others are not? Autoclaving is a method of curing concrete masonry units under high pressure and steam. The process of autoclaving reduces the linear shrinkage of the concrete masonry units to approximately one-half that which occurs under low-pressure steam curing.
