StandardDetails

This specification covers standard sand for use in the testing of hydraulic cements. Sand shall meet the requirements with respect to grading, source of sand, and absence of undesirable air entraining characteristics. Sieve analysis shall be performed by sieving the sand by hand or mechanically as prescribed. Results of the sieve analysis shall be reported as total percentage passing each sieve. Small amounts of some surfactants or other contaminants will produce air voids in mortars with 20-30 sand, graded sands or both. Tests for air-entraining potential of standard sand shall be made on a single day by a single operator. This abstract is a brief summary of the referenced standard.
