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 and health practices and determine the applicability of regulatory limitations prior to use. This hazard statement applies only to Section 9 of this specification.
