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. $$e = \frac{V_v}{V_s}\newline\newline =\frac{V_g + V_w}{V_s}$$ Where: e = Void Ratio Vv = Volume of voids (m3 or ft3) Vs = Volume of solids (m3 or ft3) Vg = Volume of air (m3 or ft3) Vw = Volume of water (m3 or ft3) The void ratio is thus a … [Read more...]
