Web🕑 Reading time: 1 minute Relative density is defined as the ratio of difference of void ratios of cohesionless soil in its loosest state and the natural state (emax - e) to the difference between void ratio in its loosest and densest state (emax - emin). Relative density determines the compactness of the cohesionless soil. […] WebThe most usual test methods to determine plastics density are: ASTM D1505: This method determines the material's density by the density-gradient technique. A material is placed in a liquid column of variable density with standard floats. These floats are usually glass beads of known density. The density of the material is then calculated.

WebGrain density describes the density of solid or mineral grains of the rock. Grain density can give an indication of the mineralogy of the rock: Dolomite, ρ = 2.8–3.1 g/cm 3; Shales, ρ = 2.65–2.8 g/cm 3 Shales are composed of several minerals that have different densities in different relative amounts.

Relative density is the ratio between absolute densities of two substances, where the divisor is considered the reference substance. If this substance is not specified, it is assumed to be water at 3.98ºC and therefore has a density of 0.999972 g/cm 3 or 999.972 kg/m 3. As per the equation, the relative density has ...
