Abstract


Pervious concrete is a type of pavement made with minimal fine aggregate and high void ratio
that allows stormwater to infiltrate into the soil and overcomes surface runoff problems. In this paper, the
utilization of fly ash as supplementary cementitious material to the mechanical properties of pervious concrete
made with recycled aggregate was investigated. Recycled aggregate was reclaimed from concrete waste to
make pervious concrete. 0%, 50%, and 100% of recycled aggregate were used to replace natural coarse
aggregate; while 0%, 15% and 25% of fly ash were used as cement replacement. The mechanical properties of
pervious concrete were evaluated by determining the compressive strength, splitting tensile strength and
flexural strength at 28 days. The results revealed that the use of recycled aggregate significantly affected the
strength of pervious concrete. Further, the experimental results show that fly ash as supplementary cementitious
material improved the compressive strength, splitting tensile strength and flexural strength of pervious concret
