Specific Gravity and Water Absorption Tests on AggregatesSpecific gravity test of aggregates is done to measure the strength or quality of the material while water absorption test determines the water holding capacity of the coarse and fine aggregates. Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of anDetermining the specific gravities of coarse aggregates The current method of specific gravity and absorption of coarse aggregate testing is based on the AASHTO T 85 and ASTM C127 standards. This approach involves the soaking of the coarse aggregate samples for 15h (AASHTO T 85) and 24. ± 4 h (ASTM C127), and drying the aggregate to its saturatedsurface dry (SSD) state with the aid of a dry absorbent cloth.
