Abstract

This study evaluates the performance, curing age importance and strength increment efficiency of using empty fruit bunch of oil palm fibre (EFBOPF) in structural concrete through a statistical model. The prediction was carried out using some concrete structural parameters (properties) through one-way analysis of variance (ANOVA) model. These parameters include density, tensile and compressive strengths, and durability. The influence of EFBOPF on concrete density, compressive strength and durability were examined using 150 x 150 x 150 mm and 100 x 100 x 100 mm concrete cubes, respectively. Also, the strength performance of EFBOPF in concrete against tensile splitting and cracks were determined using 150 x 300 mm cylindrical concretes. The compressive strengths were evaluated at 28 days; tensile strengths at 28, 90 and 120 days; durability performance was assessed at 28 and 90 days, respectively .All these parameters were tested using Universal Testing Machine, weighing balance and durability testing apparatus. The results of the experiments were modelled with ANOVA. In the Process of modelling, the correlation among the percentage of EFBOPF included, curing age and the rate of concrete’s strength increment were predicted. In accordance with ANOVA’s prediction, the compressive strengths of concrete were greatly enhanced at 0.2 and 0.4%
