Question

Difference between specific gravity of soil solid and mass specific gravity

Answer 1

The specific gravity of anything is it's density divided by the density of water. The dry density of soil is defined as the mass of soil divided by the volume of the soil (solids+voids). The density of the grains is the mass of solid particles (grains) divided by their volume( void volume not included).

Answer 2

Specific gravity of soil (GS) is defined as the ratio of the unit weight of solid particles to the unit weight of water at 4oC, specific gravity of soil particle equal from 2.60 to 2.70 .
