ASTM C887-79a(2001)
(Specification)Standard Specification for Packaged, Dry, Combined Materials for Surface Bonding Mortar
Standard Specification for Packaged, Dry, Combined Materials for Surface Bonding Mortar
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 X1 through Appendix X5 of this specification contain additional tests that may be performed on surface bonding mortar.
1.5 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.
1.6 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
