Specific gravity (SG) is the density of a stone relative to the density of water. The specific gravity of water is one (1). If a stone has a SG is 3.95, then stone has a density that is 3.95 times greater than the density of water. SG is determined by dividing the stone's weight in air by the weight of the water is displaces when it is immersed ...

The specific gravity of aggregates indirectly measures its density; hence it is the most essential parameter of strength or quality of the aggregates. Higher the specific gravity, higher is the strength. It is due to higher specific gravity there would be higher compressive strength of aggregates and hence it passes on to the concrete. 02.
