Abstract
The potential of oil palm trunk in comparison to rice husk was carried out to evaluate the potential of oil palm trunk as gypsum composite filler. The increase demand for ‗green composite‘ in construction and building industry has led to an extensive study on the potential of agricultural wastes materials. The oil palm trunk was selected due to a numbers of factors and one of the main factors is to reduce the negative impact to environment especially for the replanting process. This study investigates the effect of extractive and other chemical component in oil palm trunk and rice husk on the setting time including the physical, mechanical and flammability properties of the gypsum composite prepared. Based on the data obtained, high percentage of extractives and lignin in rice husk compared to oil palm trunk influenced the hydration of gypsum paste which resulted to longer setting time. The longest final setting was observed on 15 % rice husk SiO 2 sample with 29 minutes. The results shows that the incorporation of 20 % filler is the best formulation of filler added for all types of filler. The oil palm trunk based filler gives higher reading for mechanical testing except for internal bond strength test. The effect of filler added was observed in SEM analysis and the gypsum was detected around and between the filler added. In thermal analysis by TGA, the 20 % oil palm trunk filler added sample shows the lowest residue with 70.56 %. For flammability test, none of the sample fails and comply the standard requirement in ASTM D2859.
