And percentage of voids present in coarse aggregate is calculated with the help of specific gravity of coarse aggregate and their Loose bulk density by the following formula. % of voids = { (Gs _R)/Gs}×100. Where Gs = specific gravity of coarse aggregate and their value is 2.65. R = loose bulk density of coarse aggregate = 1.337 kg/L.
