Abstract
The use of recycle aggregate concrete (RAC) in porous concrete production could reduce the concrete waste produced from the construction works and the demolished old concrete building. This study aims to produce porous concrete using RAC as a coarse aggregate along with fibrillated Polypropylene (PP) fiber, and experimentally investigated physical properties in terms of compressive strength, strain at peak stress and modulus elasticity resulting from compressive load at three and seven days. Test results indicate that all the involved materials established excellent bond at the early age resulting in enhancement of physical properties of porous concrete specimens with increasing time from three days to seven days.
