Get PriceSeptember 1 2003 CONCRETE MANUAL 5-694.311 A. Specific Gravity Specific gravity of a material is the ratio of the mass (weight) of a given volume to the mass (weight) of an equal volume of water. Water is us ed as a standard because of its uniformity. See 5-694.123A. B. Absolute Volume See 5-694.123D. C. Total Moisture Factor
Get PriceASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete cement and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it which contains cement chemical admixtures and aggregates.
