Abstract

Disposing fly ash in to landfill of coal fire power plant initiated environmental and health problems. A lot of researchers have conducted research to study the addition of fly ash (FA) as cement replacement in pervious concrete (PC). The aim of this paper was to review the impact of adding FA as partial substitution of cement in PC. The experimental outcomes from different previous studies have indicated that the void content and permeability of PC decreased with adding FA due to filler effect of FA. The optimum substitution level of cement with FA was obtained to be 10–30%. However, with increasing the level of replacement affects the hydration procedure resulting lower strength. PC containing FA showed higher abrasion resistance and lower drying shrinkage compared to normal PC. It can be concluded that using FA as partial substitution of cement would be environmentally friendly in association with more sustainable PC.
