Abstract
This research has proposed to investigate the basic properties of oil palm ash in order to utilize as backfill materials by using x-ray fluorescence (XRF) technique to analyze the elements, compressive strength, and density of mortar containing bottom ash from oil palm. In this experiment, cement was used as a supplementary material at 5, 10 and 15 % by weight for oil palm bottom ash, which was controlled in particle size distribution in various conditions, i.e. no incubation, and incubations at 7 and 28 days. The results of the analyses and experiments showed that oil palm bottom ash contained 26.71 % calcium oxide, resulting in pozzolan materials. The compressive strength was increased when adding cement. The oil palm bottom ash replacement with cement containing 15 % by weight at 28-day incubation has a compressive strength of 2.10 MPa. Besides, the increase in cement ratio affects the increase in the density of mortars. The density of oil palm bottom ash replacement with cement containing 15 % was 5605.10 kg/m3. The development of compressive strength of mortar at 28-day incubation will increase when the percentages of cement replacement in oil palm bottom ash increased. The compressive strength of mortar increases as the curing time increases.
