Porosity is also defined as the ratio of void to the total volume.

Muhammad Taqi said:   1 year ago
Void Ratio = Volume of void/Volume of soil solid.

Porosity = volume of void/volume of solid mass.

Void ratio(e) = volume of voids/volume of solids in a given soil mass.

Range
Void ratio is never zero.

e=1
e>1
In soils having e>1, such soils are more compressible,
Less shear strength.
Less bearing capacity.
Less density and,
More previous.

Void ratio of fine grain soil is more than coarse grained soil.
Approximate void ratio of sandy soil is 0.6.

There is a co-relation that,
Porosity relates to the total volume of soil.
Void ratio relates to the Solids particles having voids within the soil.

e = Vv/Vs (i.e.) voids ratio.

Volume of void to volume of soil solid is called void ratio or volume of void to total volume of soil mass is called porosity.

Thanks @Akash.

Volume of Void/Volume of Solid is Void Ratio and Volume of Void/Volume of Soil mass is Porosity.
