Standard Specification for Air-Entraining Additions for Use in the Manufacture of Air-Entraining Hydraulic Cement
ABSTRACT
This specification covers deals with air-entraining additions for use in the manufacture of air-entraining hydraulic cement. The materials used are: cement, aggregates, and reference addition. The grading requirements for fine and coarse aggregates are specified. The following are the test methods for cement samples: chemical analysis of cement, determination of addition in the finished cement, fineness of cement, normal consistency, time of setting, autoclave expansion, air content of mortar, compressive strength of mortar, and length change of mortar. Concrete mixture preparation, weighing, proportions, and mixing methods are detailed. The test on plastic concrete is done in accordance with the following methods: consistency and unit weight and air content. The following are tests for hardened concrete: compressive strength, flexural strength, and resistance to freezing and thawing.
SCOPE
1.1 This specification covers the requirements and methods for establishing the suitability of a material for use as an air-entraining addition to be interground with the clinker in the manufacture of air-entraining hydraulic cement conforming to Specifications C150/C150M, C595/C595M, and C1157/C1157M.
1.2 The values stated in SI units are to be regarded as the standard.
1.3 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. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)
1.4 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.
