Specific Gravity Test GLGS-01

Specific gravity of soil solids is used for performing weight-volume calculations in soils. Specific gravity of soil solids, Gs, is the mass density of the mineral solids in soil normalized relative to the mass density of water. Alternatively, it can be viewed as the mass of a given volume of soil solids normalized relative to the mass of an equivalent volume of water. Specific gravity is typically expressed using three significant figures.
