Engineering behavior of recycled granulated tire rubber-filled concrete incorporating palm oil fuel ash

Abstract

Reutilization of waste materials instead of conventional aggregate can help to reduce the environmental pollution. The present study aims to investigate the feasibility and performance of using granulated tire-rubber particles (incorporating from 5% to 30% as substance of coarse aggregate) and 20% palm oil fuel ash (POFA) as cement replacement. The effect of waste tire rubber replacement was evaluated for mechanical strength of POFA concrete. The results showed that granulated tire rubber leads to concrete with lower compressive strength and showed suitable capability in flexural and tensile strength. Thus, there is an opportunity for industry to develop rubberized POFA concrete products that can be used on commercial basis. This can lead to sustainable urban development from both economic and environmental perspectives.
