Standard Method of Test for Specific Gravity and Absorption of Coarse Aggregate
This method covers the determination of specific gravity and absorption of coarse aggregate. The specific gravity may be expressed as bulk specific gravity (dry), bulk specific gravity (saturated surface-dry [SSD]), or apparent specific gravity. The bulk specific gravity (SSD) and absorption are based on aggregate after 15–19 hours of soaking in water. This method is not intended to be used with lightweight aggregates. The term relative density is interchangeable with specific gravity and may be used by some entities.
