Specific gravity of topsoil

WebSo 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. For most of the soils the value of specific gravity lies between 2.65 to 2.80. The Specific Gravity is computed as the ratio of the weight in air of a given volume of soil particles at a stated temperature to the weight in air of an equal volume of distilled water at the same temperature. The procedure that is followed towards that goal is the following: 1. Weigh the empty and clean volumetric … See more Soil is a three-phase material that consists of solid particles and voids which are filled with water and air. The specific gravity (GS) of a soil refers to the ratio of the solid particles’ unit weight to the unit weight of water. GSshould not … See more To derive the Specific Gravity of a soil, the following equipment is needed: 1. Volumetric flask marked with a thin ring at a specific point of its neck (graduation mark) 2. Balance sensitive to 0.01g 3. Vacuum pump 4. … See more To better understand how the Specific Gravity is calculated, the aforementioned measured quantities are presented in Figure 1.
