Autoclaved aerated concrete (AAC) (also referred to as autoclaved cellular concrete (ACC) or simply autoclaved concrete) is a lightweight, prefabricated concrete building material. Developed initially in the mid-1920s, it is an alternative to traditional concrete blocks and clay bricks. [1] .

Factory-produced, cement-masonry precast autoclaved aerated concrete (AAC) combines sand, cement, lime, water, and an expansion agent (like aluminum powder) to form 8-inch blocks, panels, or specialty shapes, all molded and cut precisely into dimensional units.

If you are looking to build a concrete home, one of the many concrete construction systems you can consider using is autoclaved aerated concrete (AAC blocks). In fact, this is one of our top recommendations overall, since this innovative form of concrete construction boasts many spectacular benefits.

Autoclaved Aerated Concrete (AAC) block is a low-maintenance precast building material with excellent thermal insulation and durability. The heat-insulating properties of AAC blocks keep the building cooler and prevent outside heat from entering, resulting in significant savings on air conditioning costs.
