Pervious concrete is a concrete which allows the water to pass through it. The pervious concrete contains cement, coarse aggregates, water and admixtures if needed. It has no sand in it which results in large amount of voids in the previous concrete. This sole property of having voids play a vital role in the functioning of the pervious concrete i.e; allowing water to pass through it.
The pervious concrete has a disadvantage that it has less compressive strength when compare to normal concrete this backdrop in pervious concrete because pervious concrete is a no fines concrete it has no sand the sand which plays a vital role in the strength gain of the concrete hence we in our study has concentrated in improving the compressive strength but at the same time the permeability and void content should also not affected because permeability and void content are two most important properties of the pervious concrete which makes it the pervious concrete so basically we have also conducted study on the permeability and void content of the pervious concrete.
In our study we have added different sizes of coarse aggregates such as 20 m, 12 mm, 12 +2 0 mm and we have added the sand percentages at 0 %, 0.25 %, 0.75 % and the compressive strength was checked on 7,14,28,56,90 days respectively and we have checked the permeability and void content at 28 days.
