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 Pycnometer is used for determination of specific gravity of soil particles of both fine grained and coarse grained soils. The determinination of specific gravity of soil will help in the calculation of void ratio, degree of saturation and other different soil properties.
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.
Jun 14, 2023 · 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. For exact analysis, the specifications call for distilled or demineralized water for the determination of specific gravity.
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.
Mar 1, 1980 · ( Part III ) deals with the method of test for determination of specific gravity of soils which finds application in finding out the degree of saturation and unit weight of moist soils. The unit weights are needed in pressure, settlement and stability problems in soil engineering. This
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 Specific gravity of solid particles is the ratio of mass of given volume of solids to the mass of an equal volume of water at 4 0 C . It is represented by “G”. There are many methods available to determine the specific gravity of solids but here we are discussing about the density bottle method. Specific Gravity of Solids.
The value of specific gravity is needed in calculation of soil properties like void ratio, degree of saturation, particle size analysis by hydrometer test etc. The value of specific gravity is sometimes used to determine the suitability of the soil as fill material.
Nov 14, 2023 · 5.1.1 The specific gravity of soil solids is used to calculate the density of the soil solids. This is done by multiplying the specific gravity by the density of water at 20°C. The soil solids density is nearly independent of temperature.
