    Withdrawn Rationale:

    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.

    Formerly under the jurisdiction of Committee C27 on Precast Concrete Products, this test method was withdrawn in January 2013 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

    1. Scope

    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.
