This specification covers the materials, properties, and packaging of dry, combined materials for use as surface bonding mortar with concrete masonry units that have not been prefaced, coated, or painted. The materials used as ingredients shall consist of the following: cements which shall be a Portland cement, blended hydraulic cement, hydraulic cement, or masonry cement; Type S or SA hydrated lime; Class N, F, or S pozzolan; aggregates; glass fibers; and additives. Physical properties of the packaged materials shall conform to the flexural strength, compressive strength, time of setting, and water retention requirements. The net weight, amount of mixing water, unit weight, and yield of the surface bonding mortar shall be calculated and reported.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers the materials, properties, and packaging of dry, combined materials for use as surface bonding mortar with concrete masonry units that have not been prefaced, coated, or painted.
1.2 This specification does not cover design or application. Consult the manufacturer for specific recommendations.
1.3 of this specification contains the recommended tests for evaluation of surface bonded masonry assemblages used to establish design loads for the composite wall.
1.4 through of this specification contain additional tests that may be performed on surface bonding mortar.
1.5 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.
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. This hazard statement applies only to Section of this specification.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
