Low specific gravity Aggregates are generally weaker than those with high specific gravity. Low specific gravity generally indicates porous, weak and absorptive aggregate. This property helps to the identification of good and suitable aggregates. Specific gravities of aggregate vary between 2.0 and 3.0. Specific gravities are primarily of two

5.Specific Gravity of Coarse Aggregates: It is the ratio of the dry weight of aggregate to the weight of an equal volume of water. The specific gravity of aggregate is determined along with the water absorption as specified in IS 2386 part III 1963.

Lightweight aggregates: As mentioned in the body of this paper, lightweight concrete contains aggregate that is natural or synthetic which weighs less than 1100 kg/m 3.The lightweight is due to the cellular or high internal porous microstructure, which gives this type of aggregate a low bulk specific gravity.
