WebPorosity, on the other hand, is a measure of the amount of empty space within a material. It is usually expressed as a percentage, with a value of 0% indicating a material with no empty space (i.e., a solid) and a value of 100% indicating a material that is entirely composed of empty space (i.e., a gas). WebThe void ratio is defined as the ratio of the void volume to the solid volume. Formula (7) is the relationship between the When the content of fine particles is large, the added solid volume of void ratio and the primary porosity. fine particles (Vf0’) occupy a space in the void volume (ΔVφ), and the volume of pore space are Vφ+ΔVφ.
WebThe void ratio is also an index of the fractional volume of soil pores, but it relates that volume to the volume of solids rather than to the total volume of soil. The advantage of this index over the previous one (f) is that a change in pore volume changes the numerator alone, whereas a change of pore volume in terms of the porosity will ...
