WebTwo sands having same relative density would show similar behavior under loads, although their void ratios may be different. Relative Density in Terms of Density : To determine the relative density, it is necessary to determine the specific gravity of soils in order to calculate the void ratio from dry density in the loosest, in-situ, and densest states. WebFeb 14, 2024 · The degree of saturation S is defined as the ratio of the volume of water present in a given soil mass to the total volume of voids in it.Thus, The degree of saturation is usually expressed as a percentage and is also known as percent saturation. For a fully saturated sample Vw = Vv and hence S = 1. For a perfectly dry sample, Vw = zero, and ...
