ASTM C128 – Standard Test Method for Relative Density (Specific Gravity) and Absorption of Fine Aggregate
This test method covers the determination of relative density (specific gravity) and the absorption of fine aggregates.
The relative density (specific gravity), a dimensionless quality, is expressed as oven-dry (OD), saturated-surface-dry (SSD), or as apparent relative density (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.
