This test method covers the determination of relative density (specific gravity) and the absorption of coarse aggregate. The relative density (specific gravity), a dimensionless quantity, is expressed as oven-dry (OD), saturated-surface-dry (SSD), or as relative density (apparent specific gravity). The OD relative density is determined after drying the aggregate.

The specific gravity and water absorption of fine aggregate can be determined by conducting a test according to ASTM C128 and C127, respectively. In the test, a known weight of fine aggregate is taken, and its volume is measured by submerging it in water. The specific gravity is then calculated by dividing the weight of the fine aggregate by ...
