Abstract

The conversion of large amount of available demolished concrete waste into an useful alternate source of material for making pervious concrete not only solve the solid waste management problem but it will also conserve the resources and reduce the cost of concrete.

Previous concrete is actually no-fines (or low fines) concrete with a low water cement ratio. Pervious concrete is mainly used in pavements which allows storm water to pass through which reduces run off rates, allows infiltration of the precipitation and facilitates the recharge of ground water supplies. In this study, the effect of the water cement ratio on strength and permeability characteristics of pervious concrete made with natural and recycled aggregates were evaluated.

Water cement ratio was varied from 0.27 to 0.33. The effect of water cement ratio on pervious concrete was evaluated from compressive strength test, permeability test, modulus of elasticity and split tensile strength test. When the water cement ratio is 0.27 to 0.33, the compressive strength increases with increase in water cement ratio and permeability decreases with increase in water cement ratio.
