Influence of styrene butadiene rubber latex and fly-ashon pervious concrete incorporating natural and recycled aggregate

Pervious concrete (PC) is a term refers to a concrete that has a near zero slope and is open-graded. It is normally composed of Portland cement, coarse aggregate (C.A.), less quantity of fine aggregate (F.A.), additives and water. When these components are integrated, a hardened material is formed with interconnected pores that permits easy passage of water. With the growth of construction industry demand of aggregate has also increased and also the construction demolition of structures waste gets deposited more and more per day. As we have a limited source of natural aggregate (N.A.), use of Recycled aggregate (R.A.) would be the easy and sustainable solution. In this work an attempt was made to developing PC with R.A. replacing N.A. with specific proportions. W/c ratio 0.4 and a/c ratio were kept constant for the mix design of PC. Additives such as Fly-ash(F-ash) and styrene butadiene rubber latex were (SBR) were to improve the properties such as compressive strength(c.s.), void ratio(v.r.) and density. A noticeable increment was found in c.s. using SBR up to10% of usage.
