Experimental investigation of pervious concrete by replacing coarse aggregate by coconut shell, sea shell and soda cap

The objective of our project is to study the effect of pervious concrete is a concrete which consist of coarse aggregate and cement paste with little fine aggregate or without fine aggregate. The pervious concrete also termed as non-fine aggregate is also used in structural application and it is treated as “Green building”. It requires fewer materials than the conventional concrete. It helps in recharge the ground water in pavement applications, direct drainage of water and also have superior insulation properties when used in walls. Pervious concrete has a tailored-property concrete with higher water permeability which allow the passage of water to flow through the interconnected large pore structure. The result of an experimental investigation in the development of pervious concrete with reduced cement content and coarse aggregate for sustainable permeable pavement construction. And also we used a super plasticizer conplast SPC430 to reduce the amount of water content. The compressive strength properties of pervious concrete were determined by the age of 14 days. The result about the properties like void ratio and compressive strength of concrete.
