Experimental Study On Pervious Concrete Using Different Size Of Coarse Aggregate

Abstract: Concrete is a widely used structural material consisting essentially of a binder and a mineral filler. Concrete has been the leading material since it was used and is bound to maintain its significant role in the upcoming future due to its durability, adaptability to any shape and size and many other applications. It is a composite material produced by mixing cement, inert matrix of sand and gravel or crushed stone. Pervious concrete is a type of concrete that has a low watercement ratio and contains none or very little amount of sand. This concrete has a light colour and open-cell structure because of which they do not absorb heat from the sun; they also do not radiate the heat back into the atmosphere, which reduces heating in the environment. Pervious concrete has low installation costs. In addition, it filters the storm water thus reducing the number of pollutants entering the rivers and ponds. Pervious concrete also improves the growth of trees. In the present study the behaviour of pervious concrete has been studied experimentally. Various mix proportions were prepared by replacing cement with silica fume (10% by the weight of cement), by adding super plasticizers (0.3%). Different properties of pervious concrete e.g. compressive strength, split tensile strength, permeability test at 7, 14 & 28 days have been studied experimentally.
