The pervious concrete also termed as no-fine aggregate is a natural choice for use in structural applications, and it is treated as “green binding”. It requires less raw material than the conventional concrete. Pervious concrete 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 inter connected large pore structure. This paper reports the results of an experimental investigation in the development of pervious concrete with reduced cement content and coarse aggregate for sustainable permeable pavement construction. In this research, we used a super plasticizer conplast SP430 to reduce the amount of water content. The compressive strength properties of pervious concrete were determined by the age of 3, 7 and 28days. This paper gives the results about the properties like void ratio and compressive strength of concrete. Keywords: Pervious concrete, super plasticizer SP430, Void ratio, Mix design. I. Introduction Pervious concrete was first used in the 1800 year in Europe as pavement surfacing and load bearing walls. Cost efficiency was the main motive due to a decreased amount of cement. It became popular again in the 1920 year for two storied homes in Scotland and England. It became increasingly viable in Europe after the Second World War due to the scarcity of cement. It did not become as popular in the US until the 1970 year. Pervious Concrete has been around for hundreds of years. The Europeans recognized the insulating properties in structural buildings. As it is true with any material and construction technique, there is a science to it and a best way to conduct the construction. Education and experience is the key to success. The coastal states have experienced pervious concrete for over 20 years. The hesitation to move into the Midwest and Northern States was mainly due to freeze/thaw concerns. Now that those concerns are no longer considered a problem, the product has moved quickly across the United States. In the 1990’s the U.S. 1.1 Advances in Pervious Concrete: Pervious concrete is advantages for a number of reasons. Of top concern is its increased permeability compared with conventional concrete. Pervious concrete shrinks less, has a lower unit weight, and higher thermal insulating values than conventional concrete. 1.2 Super Plasticizer Conplast Sp430: The Conplast SP430 is based on Sulphonated Napthalene Formaldehyde and is supplied as a brown liquid instantly dispersible in water. ConplastSP430 has been specially formulated to give high water reductions up to 25% without loss of workability or to produce high quality concrete of reduced permeability.
