More Details· Specific Gravity and Absorption (ASTM C 127/C 128, AASHTO T-85/T-84): Specific Gravity evaluates how voids in the aggregate particles are considered. Absorption evaluates the amount of water an aggregate will absorb. Both of these are important for concrete mix design.

More DetailsRelative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" is often preferred in ...
