Weight Of Mm Aggregate

Specific gravity is defined as the ratio of weight of aggregate to the weight of equal volume of water.The specific gravity of an aggregate is considered to be a measure of strength or quality of the material.Aggregates having low specific gravity are generally weaker than those with high specific.Specific gravity of aggregate 6.3 mm.
