This test method covers the determination of relative density (specific gravity) and the absorption of fine aggregate. The relative density (specific gravity), a dimensionless quality, is expressed as oven-dry (OD), saturated-surface-dry (SSD), or 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.
MTI laboratories are accredited by TAF (ISO/IEC 17025) to perform testing standard CNS 487 for Relative Density (Specific Gravity) and Absorption of Fine Aggregate.
