A lightweight cellular concrete building material, made from sand, cement, lime, gypsum, water and expansion agent, autoclaved aerated concrete (AAC) is manufactured as either steel reinforced panels or unreinforced blocks.

Thanks to its many benefits – which include strength, excellent thermal and acoustic properties, fire resistance, non-toxicity, low cost, workability, and ease of handling – AAC is suitable for a broad range of architectural systems and applications.

In residential applications it is used for exterior walls, floors, and fencing. In multi residential developments, it is used on zero boundary, party walls, dual zero boundary walls, and more. In commercial applications, it is used in intertenancy and corridor walls, in fire tunnels, on façades, while in civil projects it is often used for acoustic fire walls and sound barriers.

Given this versatility, the popularity of ACC is on the rise. Considering the various regulations associated with the material, its specification should always involve attention to detail. This CPD Live session is intended to help those looking to use it to do just that. Our speakers will identify and outline strategies to help you accurately assess, and then integrate, AAC Systems into your projects.
