Abstract
This specification addresses the dimensional tolerances, maximum limits for drying shrinkage, and shipping and handling requirements for solid unreinforced masonry units manufactured from autoclaved aerated concrete (AAC). The masonry units shall be composed entirely of AAC material and classified according to their strength class. The units shall conform to compressive strength, dry bulk density, and drying shrinkage requirements, which shall be determined in accordance with referenced ASTM documents.
Scope
1.1 This specification covers solid, unreinforced masonry units manufactured from autoclaved aerated concrete (AAC), a cementitious product. This specification addresses dimensional tolerances, maximum limits for drying shrinkage, and shipping and handling.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
