Dry and saturated unit weight of soil
WebIt is the ratio of the weight/mass of soil in dry conditions to the total volume of soil mass (V). It is represented as ‘γ d ’ /‘ρ d ’. \(\begin{array}{l} γ_d=\frac{\text { Weight of soil in … WebThe degree of compaction of a soil is measured in terms of dry unit weight, which is the amount of soil solids that can be packed in a unit volume of the soil. The unit weight of a soil provides an idea about its strength, compressibility, and permeability.
