Topic: Performance of Palm Oil Fuel ASH(POFA) in Suppressing the Alkali Silica Reaction
Abstract: Due to the grow in vegetable oil demand from all over the world, huge of palm oil products produced. This will cause a million of ones of solid waste in form of oil palm shells or also known as palm oil fuel ash (POFA) is formed. Thus issue arising on the way to disposal of these agricultural wastes which can cause environment issue. This study was done to identify the potentials of these wastes as partial replacement in concrete. The main objective for this study is to study the effect of the POFA in preventing expansion due to the Alkali-silica reaction (ASR). POFA is identified by past researchers as materials that can reduce the ASR reaction. Compressive strength test and Accelerated Mortar Bar test, AMBT (ASTM C1260) is used to get the result on compressive strength value and percentage of expansion of the sample. When POFA is added to the mixes in mortar, the expansion of mortar is reduce and at the optimum percentages of POFA added, the compressive strength is higher than the control mortar sample.
