ASTM C 128 - 07a Standard Test Method for Density, Relative Density (Specific Gravity), and Absorption of Fine Aggregate

American Society for Testing and Materials (ASTM). Current edition approved Aug. 1, 2007. Published September 2007. 7 p. This test method covers the determination of the average density of a quantity of fine aggregate particles (not including the volume of voids between the particles), the relative density (specific gravity), and the absorption of the fine aggregate. Depending on the procedure used, the density, in kg/m3(lb/ft3) is expressed as oven-dry (OD), saturated-surface-dry (SSD), or as apparent density. Likewise, relative density (specific gravity), a dimensionless quality, is expressed as OD, SSD, or as apparent relative density (apparent specific gravity).
