Compressive and Flexural Strength Development of Oil Palm Frond Fibre-Reinforced Sandcrete Blocks: ANOVA, Tukey and Regression Analysis

Oil palm frond fibre (OPFF) offers a potential agricultural-waste reinforcement for sandcrete, but its influence on compressive and flexural strength may differ with fibre dosage and curing age. This study evaluated the strength development of sandcrete containing 0, 0.5, 1.0, 1.5 and 2.0% OPFF by mass of cement. Forty...
