relation between water cement ratio and strength of concrete

What is the Right Water-Cement Ratio for Mix Design?

A mix design with a lower water-cement ratio or higher cement content will give low permeability concrete. A high strength concrete tends to give a less pervious concrete. This will increase the durability of the concrete structure. The figure-3 below shows the relationship between concrete water-cement ratio and the coefficient of permeability.
