ASTM C127 – Standard Test Method for Relative Density (Specific Gravity) and Absorption of Coarse Aggregate
This test method covers the determination of relative density (specific gravity) and the absorption of coarse aggregates.
The relative density (specific gravity), a dimensionless quantity, is expressed as oven-dry (OD), saturated-surface-dry (SSD), or as apparent relative density (apparent specific gravity).
The OD relative density is determined after drying the aggregate.
The SSD relative density and absorption are determined after soaking the aggregate in water for a prescribed duration.
