Question

Quizplus · Accepted Answer

Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material that provides excellent insulation properties and is more energy-efficient than standard concrete masonry units (CMUs). It is made by adding a foaming agent to concrete in a mold, then wire-cutting blocks or panels from the resulting 'cake' and 'cooking' them with steam (autoclaving).
