The Specific Gravity of Soil is defined as the ratio of the weight of a given volume of the material to the weight of an equal volume of distilled water. It is an important parameter in soil mechanics for the calculation of the weight-volume relationship. This specific gravity, G” is defined as.
The specific gravity of soil is the weight of a given volume of the soil divided by the weight of the same volume of water at 20°C. In effect, it shows how much heavier (or lighter) the soil is in comparison to water.
The specific gravity (G S) of a soil refers to the ratio of the solid particles’ unit weight to the unit weight of water. G S should not be confused with the soil density since it is a dimensionless unit and expresses the ratio of two particular densities.
The specific gravity (G s )of a material is the ratio of the mass of a unit volume of soil solids at a specific temperature to the mass of an equal volume of gas-free distilled water at the same temperature. The specific gravity of soil is usually reported at 20°C.
Mar 1, 1980 · determination of the ,specific gravity of soil particle of fine grained soils ( see Note ) . NOTE - The method may also he used for medium and coarse grained soils if
This test is done to determine the specific gravity of fine-grained soil by density bottle method as per IS: 2720 (Part III/Sec 1) – 1980. Specific gravity is the ratio of the weight in air of a given volume.
Specific gravity is a fundamental property of soils and other construction materials. This dimensionless unit is the ratio of material density to the density of water and is used to calculate soil density, void ratio, saturation, and other soil properties.
The determinination of specific gravity of soil will help in the calculation of void ratio, degree of saturation and other different soil properties. Specific Gravity of Soil By Pycnometer Method. Equipment for Specific Gravity Test of Soil. The major measuring equipment in this test is Pycnometer.
So Specific gravity of solids, which is denoted by G or Gs, can be defined as the ratio of the unit weight of solids to the unit weight of water, which is weight of solids of a given volume, to the weight of equivalent volume of water at 4 degree centigrade.
Mar 5, 2021 · 2.4.3.1. Specific Gravity. Specific Gravity is the ratio of the density of one material compared to the density of pure water (ρ l = 1000 kg/m 3). \[\ \mathrm{G}_{\mathrm{s}}=\frac{\rho_{\mathrm{s}}}{\rho_{\mathrm{l}}}\tag{2-1}\]
