Most of the natural aggregates have specific gravity which lies in a range between 2.6 and 2.7. A low specific gravity indicates lower density, higher porosity and therefore poor durability and low strength. Higher specific gravity means higher density and lower porosity.It also means heavier and more compact concrete.
