Abstract- 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.
