Void Ratio
The void ratio of coral sand is between 0.8 and 2.97, which is much higher than the usual range (0.4–0.9) of quartz sand. Obviously, the greater the inner void ratio of particle, the more possibility of breaking under the external force, thus showing greater compression and deformation degree.
Void ratio
Soil void ratio (e) is the ratio of the volume of voids to the volume of solids: e = (V_v) / (V_s) Where V_v is the volume of the voids (empty or filled with fluid), and V_s is the volume …

Soil porosity
Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil. The posoity and the void ratio are inter-related as follows: e = n /(1-n) and n = e / (1+e) The value of void ratio depends on the consistence and packing of the soil.
