ASTM C1452 – Standard Specification for Reinforced Autoclaved Aerated Concrete Elements
This specification covers load-bearing and nonload-bearing reinforced autoclaved aerated concrete (AAC) floor, roof, wall, and stair elements used as components for building construction.
Autoclaved aerated concrete is a cementitous product based on calcium silicate hydrates in which low density is attained by the inclusion of an agent resulting in macroscopic voids and is subjected to high-pressure steam curing.
Installed units covered by this specification shall be protected against direct exposure to moisture using a coating material accepted by the AAC manufacturer.
