WebDec 1, 2002 · The void ratio range provides a general basis for comparative evaluation of material properties over the entire range of cohesionless soils. Important issues related to the laboratory procedures used for determination of e m ax and e m in as well as their applicability to fines-containing sands are also addressed. Webe = void ratio w = water content or moisture content Density of water and gravitational constant ρw = 1000 kg/m 3 ρw = 1 g/cc ρw = 62.4 lb/ft 3 g = 9.81 m/s 2 g = 32.2 ft/sec 2 Relative Density Relative density is an index that quantifies the state of compactness between the loosest and densest possible state of coarse-grained soils.
WebJul 27, 2024 · Relation Between Porosity (n) & Void Ratio (e) By the definition of porosity, we have, n = Vv/V Where, Vv = Volume of voids in a given soil mass. V= Total volume of the soil mass = Volume of voids in the given soil mass (Vv) + Volume of soil solids in the given soil mass (Vs). Thus, n = Vv / (Vv + Vs) WebThe void ratio is the ratio of the volume of voids (open spaces, i.e. air and water) in a soil to volume of solids. The void ratio is thus a ratio which …
WebApr 12, 2024 · The ratio of the total volume of voids to the volume of solids is called the void ratio e = V v /V s e > 0 In general e > 0, i.e. There is no upper limit for the void ratio Note: Porosity is always less than 100% but the void ratio … http://www.geotechdata.info/parameter/void-ratio

The void ratio of a mixture is the ratio of the volume of voids to volume of solids. It is a dimensionless quantity in materials science, and is closely related to porosity as follows: $${\displaystyle e={\frac {V_{V}}{V_{S}}}={\frac {V_{V}}{V_{T}-V_{V}}}={\frac {\phi }{1-\phi }}}$$and See more • Volume change tendency control. If void ratio is high (loose soils) voids in a soil skeleton tend to minimize under loading - adjacent particles contract.
