ASTM C1591

Full Name

ASTM C1591 – Standard Test Method for Determination of the Modulus of Elasticity of AAC


This procedure covers the determination of the modulus of elasticity of Autoclaved Aerated Concrete (AAC) in compression by determining the stress-strain behavior. 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.
