ASTM C1386

Full Name

ASTM C1386 – Standard Specification for Precast Autoclaved Aerated Concrete (AAC) Wall Construction Units

Scope

This specification covers solid nonload-bearing and load-bearing precast concrete wall units made from autoclaved aerated concrete.

Precast autoclaved aerated concrete (AAC) is a cementitious 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.

The precast autoclaved aerated concrete wall units are large-size solid rectangular prisms, which are to be laid using thin-bed mortar.

Installed units covered by this specification shall be protected against direct exposure to moisture using a coating material accepted by the AAC manufacturer.
