Abstract

Abstract:Pervious Concrete is a special type of concrete, which consist of cement, coarse aggregates, water and if required admixtures and other cementitious materials. As there are no fine aggregates used in the concrete mix, the void content is more which allows the water to flow through its body. So, the Pervious Concrete is also called as Permeable Concrete and Porous Concrete.There is lot of research work is going in the field of Pervious Concrete. The compressive strength of Pervious Concrete is less when compared to the conventional concrete due to its porosityand voids. Hence, the usage of Pervious Concrete is limited even though it has lot of advantages. If the compressive strength and flexural strength of Pervious Concrete is increased, then it can be used fora greater number of applications. For now, the usageof Pervious Concrete is mostly limited to light traffic roads only. If the properties are improved, then it can also be used for medium and heavy traffic rigid pavements also. Along with that, the Pervious Concrete eliminates surface runoff of storm water, facilitates the ground water recharge, and makes the effective usage of available land.The Pervious Concrete can be an important part of context-sensitive construction and low-impact development used to improve water quality by capturing the “first flush” of surface runoff, reducing temperature riseinreceiving waters, increasing base flow, and reducing flooding potential by creating short term storage detention of rainfall. In order to fully utilize these benefits, the hydrological behavior of the pervious concrete system must be assessed. The hydrological performance is usually a key parameter in decisions to use this material as a best management practice for storm water management.Pervious Concrete is an important application for the sustainable construction and is one of many low impact development techniques used by builders to protect water quality.Index Terms - Concrete, cement, Pervious Concrete structure, storm water
