Abstract:

Pervious concrete is a special type of concrete made with cement paste and coarse aggregates. Amount of fine aggregates in porous concrete varies from no fines to lesser quantity of fines. Pervious concrete is often referred as porous concrete made exclusively with special property of very high permeability. As the porous concrete is low in strength it can be used on low traffic volume roads for storm water management. Porous concrete is effective in reducing runoff and recharge ground water table. For hot and arid regions like Oman wherein the rain fall is scanty, ground water tables are deep and soils are mostly gravels, porous concrete use should be encouraged in secondary roads, sidewalks, parking area etc. In urban and built up areas, porous concrete can be used instead of conventional road construction material like Bitumen and concrete for surfacing the roads. A good quality concrete need to be designed to reduce runoff and meet the specifications of low traffic volume roads and paving areas. In this research work mix design has been carried on conventional concrete. Fine aggregates are replaced by coarse aggregates and concrete with 0% fines are prepared and tested for its mechanical and hydraulic properties. Fine aggregates are added at 10% increments up to 40% of total volume of aggregates and cube and cylinders are casted and tested for 7day and 28 day strength. Also permeability of porous concrete is examined for different % of fines for its use in pavements. Laboratory test results reveal that a porous concrete with 20% fines is more suitable for low volume traffic roads and parking areas.

Keywords:

No fines concrete, Porous concrete, Storm Water Management, Porous concrete for parking areas and low volume roads.
