Experimental investigations on polymer modified pervious concrete

Pervious concrete, a concrete free of fine aggregates, is a type of porous concrete which has attracted the attention of many researchers recently. Attempts to improve the characteristics of such concrete continue In this study, pervious concrete mixes, containing various proportions of Styrene Butadiene Rubber (SBR) of (0, 5, 8 % wt of cement), with two water/cement (0.30 and 0.35) were produced. The influence of these proportions of SBR on the physical and mechanical properties of the mixes was investigated. These properties are compressive strength, density, water discharge, ultrasonic pulse velocity (UPV) and modulus of rupture. The results revealed that there is a positive effect of using pervious concrete containing various proportions of the polymer compared to the mixes without polymer. A Fourier transformation infrared spectroscopy test (FTIR) was also utilized to demonstrate the effect of the polymer on the mortar structure. (C) 2020 The Authors. Published by Elsevier Ltd.
