Abstract:
Palm oil fuel ash and fly ash are industrial by products that are produced in coal-fired power station and palm oil industry. Due to the abundancy of coal- fired power plant and palm oil industry in Malaysia, the increasing amount of palm oil fuel ash and fly ash generated each year is not well utilised. This study aims to give reuse value to palm oil fuel ash and fly ash by investigating the appropriate mix proportion to produce artificial lightweight aggregate that is suitable for construction applications. The four acceptable mixes using on of fly ash to palm oil fuel ash with binder percentage are 4F6P15, 4F6P20, 4F6P25 and 5F5P20 mix [such as Mix-1 with 40% Fly ash and 60% POFA with 15% binder, Mix-2 with 40%Fly ash and 60% POFA with 20% binder, Mix-3 with 40% Fly ash and 60% POFA with 25% binder, and Mix-4 with 50% Fly ash and 50% POFA with 20% binder are determined. These mixes are able to produce fresh pellets of crushing strength greater than 0.5MPa. The fresh pellets were sintered with microwave oven in the presence of silicon carbide susceptor and zirconium insulation for 10 minutes, 15 minutes and 20 minutes. The properties of sintered aggregate namely crushing strength (show strength values), particle density (show values) and water adsorption (show values) was investigated. Scanning electron microscopy analysis was conducted to study the microstructure of sintered aggregate (writing SEM findings). The sintered aggregate strength increases at 10 minutes sintering, decreases at 15 minutes and increases back sharply at 20 minutes sintering. The increase in particle density result in decrease in water absorption. Pls write significance of this finding.
