The cement concrete prepared by mixing aluminum into it is called “Autoclaved Aerated Concrete” (AAC). In this type of concrete, aluminum powder is added to the cement mixture. The aluminum reacts with the alkaline components of the cement, producing hydrogen gas that forms tiny bubbles within the mixture. This process creates a lightweight, porous material with excellent thermal insulation properties. AAC is widely used in construction due to its reduced weight, improved thermal efficiency, and ease of handling, making it suitable for walls, floors, and roofs.
