Standard Specification for Packaged, Dry, Combined Materials for Surface Bonding Mortar
ABSTRACT
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.
SCOPE
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 Appendix X1 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 Appendix X2 through Appendix X5 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 9 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
