Acid resistance of OPS lightweight concrete with unground POFA as partial fine aggregate replacement

Oil palm shell (OPS) and Palm oil fuel ash (POFA) is a waste material generated in palm oil mill. This waste material generally dumping at open field area causing health hazards and environmental pollution problems. Due to its abundance and characteristics, many researchers have evaluated its potent...
