Standard Test Method for Determination of the Modulus of Elasticity of AAC (Withdrawn 2013)

Significance and Use

This test method is intended to provide simplified and economical means for obtaining data on the chord modulus of elasticity developed for different types of AAC grades.


1.1 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.

Note 1 - Installed units covered by this standard must be protected against direct exposure to moisture using a coating material accepted by the AAC manufacturer.

1.2 AAC tested in accordance with this test method shall comply with Specification C 1386.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
