| Summary: | This research intention to utilize of Palm Oil Fuel Ash (POFA) as cement replacement by using two different methods. POFA is a waste product obtained from burning of palm oil and palm kernel shell as a fuel in palm oil mill boilers that have been identifying as a good pozzolanic material. The using of partial replacement of cement by Palm Oil Fuel Ash (POFA) as a pozzolanic material in producing high strength of concrete compared with conventional concrete of grade M30. Moreover, the effective consumption of Palm Oil Fuel Ash (POFA) in concrete would help to cut down the cost of concrete production, also can reduce the environmental issue and can fix the landfill problem from the disposal of those wastage. In this study was discussed the strength properties of POFA in different partial replacement percentage and compares with the control mixtures. It used to replace Portland cement by 5% and 10% by weight of the cementitious material to make high strength concrete with the different method that is powder and liquidation method. The compressive and flexural strength of POFA concrete due to 3, 7 and 28 days of curing ages was investigated. In this study, found that 5% of partial replacement by using powder method can achieved high strength compare to another method and percentage. It shows that POFA is an outstanding pozzolanic material that can be use as another partial cement replacement concrete. Therefore, it can recommend that the optimal replacement for Palm Oil Fuel Ash (POFA) is 5% for good strength in compressive and flexural. |
