Jan 15, 2019The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm3. Therefore, these numbers translate directly to g/cm3, or tonnes per cubic meter (t/m3).

Typical gravel density (dry) is between 1520 and 1680 kg/m3 (95 to 105 lbs/ft3). If it is mixed with sand the density is around 1920 kg/m3 or 120 lbs/ft3 [1]. Common gravel and crushed stone sizes.
