Influence of Specific Gravity on Weight of Proportions of

Feb 16, 2015 The specific gravity of aggregates is commonly ranging from 2.6 to 3.0. Specific gravity is used to separate deleterious particles, lighter than other particles, from good aggregates. It is used in calculating the solid volume of aggregates in concrete mix. Determination of the porosity of the aggregate is often necessary.
