value of density of crushed rocks

Understanding porosity and density

Grain 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.
