Palm Oil Fuel Ash as A Cement Replacement in Concrete
This study investigated the effect of Palm Oil Fuel Ash as a pozzolan replacement in concrete and the main findings are: a) Palm Oil Fuel Ash is an effective pozzolan to replace cement at low percentages with the optimum level is at 2.5%
Palm oil fuel ash (POFA), a waste material obtained from burning of palm oil husk and palm kernel shell as fuel in palm oil mill boilers, which has been identified as a good pozzolanic material. Palm oil fuel ash which contains siliceous compositions produces a stronger and denser concrete. Effective consumption of POFA in concrete, would
Palm Oil Fuel Ash: Promising supplementary cementing
Palm Oil Fuel Ash (POFA) is by-product obtained by burning of fibers, shells and empty fruit bunches as fuel in palm oil mill boilers. In this investigation, three ashes were collected from different palm oil mills around Malaysia and namely CAPOFA, ALPOFA and KTPOFA. The ashes were ground to 45 μm before replace 20% by weight of cement in

Compressive Strength of Palm Oil Fuel Ash Concrete
The results shows that concrete with 15% replacement gave the highest compressive strength and only series of concrete incorporating of fly ash surpass the strength of palm oil fuel ash concrete
oil clinker as sand replacement in lightweight concrete production, oil palm shell as full coarse aggregate replacement and palm oil fuel ash as partial cement replacement. The paper discusses the effect of palm oil waste content in concrete towards workability and strength performance of palm oil waste lightweight concrete. 2. EXPERIMENTAL METHODS
Utilization of palm oil fuel ash in concrete: A review
The results shows that concrete with 15% replacement gave the highest compressive strength and only series of concrete incorporating of fly ash surpass the strength of palm oil fuel ash concrete
Abstract. The binary effect of pulverized fuel ash (PFA) and palm oil fuel ash (POFA) on heat of hydration of aerated concrete was studied. Three aerated concrete mixes were prepared, namely, concrete containing 100% ordinary Portland cement (control sample or Type I), binary concrete made from 50% POFA (Type II), and ternary concrete containing 30% POFA and 20% PFA (Type III).
Compressive Strength and Density of Oil Palm Shell
environmental polluting waste has result in innovation of oil palm shell lightweight aggregate concrete containing palm oil fuel ash as partial cement replacement. The current investigation looks into the effect of curing methods on density and compressive strength performance of this newly modified lightweight concrete.
The palm‐oil industry produces large amounts of solid wastes. Shell and fiber wastes are used extensively as fuel for steam production in palm‐oil mills. After combustion, a large quantity of ash is produced and creates problems of disposal. The feasibility of using the shell and fiber ash as a construction material is studied. The material
