Abstract
Pervious concrete Consist Portland cement, coarse aggregate, water and additives with little fines or no fine aggregate. Pervious Concrete helps environment by managing storm water, reducing heat island effects and water runoff. There is no IS code for the design of pervious concrete. So I try hit and trial method to achieve the strength with proper water cement paste. On the trial basis, the different aggregates with different shape and size are used. For the first trial mix, the water to cement ratio is 0.4 and aggregate to cement ratio is 4:1. Results show that the strength of the 10mm rounded shape aggregate has higher strength than 10mm chips shape and 10mm chips shape aggregate has higher strength than 20mm aggregate. For the second trial, the different water-cement ratio is used for the higher in the first trial mix. In the second trial mix, the water-cement ratio is 0.35 for the rounded aggregate with aggregate to cement ratio is same. The result shows that the strength is higher for the higher water-cement ratio.
