Influence of moisture and particle size on coal blend bulk …

The bulk density initially decreases, since coal density is 1.4 g/cm 3 and the water density is 1g/cm 3. Thereby, the substitution of coal by water justifies the result found. This can also be explained by the fact that the water enables hydrophobic coal particles to repulse each other, increasing the free space and, consequently, decreasing ...

Density of 3" crushed rock

 · 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. Given a void ratio of 0.3 and a specific gravity of 2.7, the dry density would be: GammaD=0.7*62.4*2.7=118 pcf.
