Necessity of Permeability

Necessity of Permeability

A low permeability concrete generally possesses high strength and is resistant to the ingress of water and salt solutions. The permeability of concrete can be measured by determining the rate of flow of moisture through concrete. Since the porosity of concrete resides in the paste, the permeability of concrete should be cement aggregate interface. Impermeable concrete is required for water retaining structures and construction below grade.
