Utilization of Palm Oil and Electric Power Plant Fly Ash Waste Material as a Clay Replacement in Bricks

Abstract:

In this study several types of bricks were produced containing substituent from industrial wastes. The industrial wastes used are palm oil and electric power plant fly ash. These waste products are used to replace the natural ingredient in the manufacturing of brick clay namely as clay. Conventional bricks are produced from clay with high temperature kiln firing or from ordinary Portland cement (OPC) concrete. At the present, the world's natural resources are decreasing so many alternative actively pursued to ensure that the natural ingredients will remain unchanged for the use of the more significant and worthwhile. In this study, some suggestions have been proposed where the using of fly ash as a clay replacement materials in the percentage of 20%, 40% and 60%. The several laboratory experiments was carried out, where the high compressive strength with 20% of fly ash replacement is 15.5 N/mm² while for the 20% of power plant fly ash replacement provide a compressive strength of 103 N/mm². For optimum water absorption, the rate is 17.05% which is from 20% of palm oil fly ash replacement while for brick from 60% power plant fly ash, the rate of water absorption is 4.96%. Therefore, this study can contribute to recycling the industrial waste material as a replacement material in brick in Malaysia. Recycling waste is one way to ensure that waste management can be controlled.
