Performance of Pervious Concrete Using Sewage Sludge Ash with Different Sizes of Coarse Aggregate

India is a developing country and we can observe that there is rapid growth of the infrastructure due to which the earth surface is covered by buildings, roads etc. Because of that the groundwater is depleting. This can be recharged if the precipitated water is allowed to substrata of the soil, this can be done by using Pervious concrete. Pervious concrete is a special type of concrete that has high infiltration rates. It allows water to pass through it directly and reduces the runoff on the site. It is having more merits than demerits when compared with normal concrete. Hence the introduction to Pervious Concrete Pavements in place of normal pavements came into existence to collect the rain water from the surface. The aim at this project is to study the performance of pervious concrete using sewage sludge Ash (waste product) as replacement to cement along with different gradations of coarse aggregates.
