Abstract: Pervious concrete also referred to as “No-fine Concrete” or “Porous Concrete” is material comprised of narrowly graded coarse aggregates, cementitious materials, water and admixture and in some cases fibers. Carefully controlled amount of water and cementitious materials are used to create a paste that forms a thick coating around aggregate particles without flowing off during mixing and placing. The pervious concrete is a special high porosity concrete that allows water from precipitation and other sources to pass through, thereby reducing the runoff and recharging ground water level. Its void content ranges from 18 to 35%, compressive strength from 4Mpa to 30Mpa. The infiltration rate is fall in range of 100 to 750 liter per m 2 . And due to high void content pervious concrete is also lightweight with density 1600 Kg/m3 to 2100 Kg/m3. Pervious concrete traditionally used in parking areas, area with light traffic, pedestrian walkways and green houses, contributing to sustainable development. In present paper the various mixes of previous concrete were prepared with different amount of aggregates, cement and fly ash to find the properties like compressive strength, permeability and flexural strength to check its suitability as pavement material.
