Relative Density (Specific Gravity) and Absorption of ...

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.

Feb 14, 2020  For a coarse aggregate, a higher bulk density means that there are few voids which are to be filled by the fine aggregate and cement. Thus, bulk density also depends upon the degree of packing. Procedure: Note down the dimensions and empty weight of the measuring container and compute its volume. For the determination of the loose bulk density ...
