ASTM C1692-10

Standard Practice for Construction and Testing of Autoclaved Aerated Concrete (AAC) Masonry

SIGNIFICANCE AND USE
This practice applies to the materials and methods used in the construction of AAC masonry. It directly references the AAC materials standards under the jurisdiction of ASTM Committee C27 and the workmanship requirements of TMS 602-08 / ACI 530.1-08 / ASCE 6-08 and supplements those workmanship requirements with additional requirements particular to AAC masonry.
SCOPE
1.1 This practice applies to construction and testing of masonry made of AAC units. It includes or references terminology, material specifications, and methods of test. It references specifications and test methods.
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.

INTRODUCTION
Masonry units of autoclaved aerated concrete (AAC) can be produced with dimensional tolerances
as small as 0.06 in. (1.5 mm). As a consequence, AAC masonry units can be laid with mortar joints
approximately 0.38 in. (10 mm) thick, and also with thinner joints. The exterior face of the resulting
