Abstract

Oil palm fiber is one of the agricultural by-products from palm oil industry. If it is not treated properly, it may become solid waste in landfills. However, oil palm fiber is high in tension and low in density, hence many researches were conducted by scientists and engineers regarding the application of this fiber on the concrete structure material. In this project, oil palm fiber was applied to the concrete in order to produce the lightweight concretes and determine the optimum composition of this concrete. The ingredients of these oil palm fiber concretes are oil palm fiber, fly ash, sand, cement, and water. Thirteen types of concrete specimens with different percentage of ingredients were prepared. The effects of oil palm fiber as well as fly ash on the physical and mechanical properties of concrete were studied and evaluated through several testing. Density test and water absorption test were carried out by using a densimeter and some calculation. Dino Lite microscope was used to conduct the microstructural analysis, by observing and analyzing the microstructure of these concrete specimens. Furthermore, compression test and splitting tensile test were carried out by using an Instron Machine. Density, percentage of water absorption, microstructure, compressive strength and, splitting tensile strength were obtained from these testing. The data and results were tabulated in tables and analyzed by using graphs and charts. As a result, the optimum composition of oil palm fiber concrete was obtained with lower density, lower water absorptivity, good microstructure, and relatively higher compressive and splitting tensile strength. The optimum concrete specimen is D2 with the composition of 1 % oil palm fiber, 9 % fly ash, 40 % sand, 50 % cement, and extra 50 % water.
