ASTM C387 / C387M - 11a standard specification for packaged, dry, combined materials for mortar and concrete


Source: ASTM International

This specification covers the production, properties, packaging, and testing of packaged, dry, combined materials for concrete and mortars. Concrete mixtures covered by this specification includes high-early strength concrete, normal strength concrete, normal weight concrete, high-strength mortar, and mortars for unit masonry. The purchaser shall specify the material desired as concrete, high strength mortar, or mortar for use with unit masonry, and the respective physical requirements. Materials used as ingredients in packaged, dry, combined materials for mortar and concrete shall be composed of aggregates, air-entraining admixtures, blended cement, chemical admixtures, fly ash, ground granulated blast-furnace slag, hydrated lime, latex and powder polymer modifiers, masonry cement, mortar cement, Portland cement, and silica fume. All aggregates shall be dried, without disintegration, to specific moisture content The proportions of cementitious material and aggregate shall be such that the strength requirements will be met. Packaged, dry, combined materials for concrete, high strength mortar and mortar for use with unit masonry shall conform to the respective compressive strength requirements. Scales conforming to the standards will be used for sampling concretes from a single batch using a sufficient quantity. A slump test will be performed to check if additional water is required. In sampling mortar, the contents of an entire package of dry, combined material for mortar for unit masonry or for concrete mortar shall be used. Mortar mixing equipment, which must be provided with a bowl positioning adapter, shall be used to ensure clearance for the largest size aggregate in the mix being tested. The specification includes the following testing methods for mortar: compressive strength, density and yield, air content, and water retention.

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. Scope

1.1 This specification covers the production, properties, packaging, and testing of packaged, dry, combined materials for concrete and mortars. The classifications of concrete and mortar covered are defined in Section 3.

Note 1—The scope of this standard does not cover mortars for unit masonry. Dry preblended mortars for unit masonry are covered by Specification .

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 The following safety hazards caveat pertains only to the test method portion of this specification. 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.
