Density of 3" crushed rock

 · For me crushed rock is pretty well-graded and there''d be plenty of finer grains to infill the voids of the larger aggregate. Bear in mind coarser soils have a lower void ratio than finer soils. So, just because you can see the voids of a large aggregate material, does not mean the void ratio is greater than a fine grained soil.

The Density of Common Rocks and Minerals

 · The 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/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
