# Void ratio

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 The void ratio is the ratio of the volume of voids (open spaces, i.e. air and water) in a soil to volume of solids

Void ratio — The ratio of the volume of void space in a soil sample to the volume of solid particles. Water content — The ratio of the weight of water to the weight of solids of a soil sample Void ratio is the ratio of volume of void to the volume of soil solid. It tells us the amount of voids (space between soil other than soil solids) present in the soil. Void spaces can be either filled with air (in case of dry state) or water (as in case of fully saturated state) or some times both (as in case of partially saturated state) 5.1 Density is a key element in the phase relations, phase relationships, or mass-volume relationships of soil and rock (Appendix X1).When particle density, that is, specific gravity (Test Methods D854) is also known, dry density can be used to calculate porosity and void ratio (see Appendix X1).Dry density measurements are also useful for determining degree of soil compaction Void ratio is defined as the void volume to the solids volume existing in the soil.
