ABSTRACT Recent years have seen a rise in both concrete costs and environmental impact. M-sand containing coconut and jute fibers was used in traditional concrete. This study explores the potential of eco-friendly coir and jute fibers as a sustainable alternative to conventional fiber reinforcement in concrete production. The coconut and jute-fiber concretes are made using a set percentage (0.5%) of the volume’s total weight of concrete. 18 cube and 18 prism specimens in total are cast and evaluated. Each type of fibre reinforced concrete specimens such as Jute fibre reinforced concrete mix (CMJF) and coconut fibre concrete mix (CMCF) contains 0.5% of the volume’s total weight of the concrete mixture. This consistency was maintained to guarantee a fair comparison among the different mix designs. The two crucial strengths of compressive and flexural force are investigated and their ratios are also evaluated. In the design mix constantly M sand was taken. The three mix designs were traditional M-sand concrete, M-sand concrete with jute fiber and M-sand concrete with coconut fiber. In this study, native river sand is fully substituted with M sand and no chemical admixture is added. The mechanical properties of compressive and flexural strength tests were checked with mean and standard deviation. The coconut-fiber M-sand concrete has reached its utmost compressive and flexural strengths of 19.3% and 24.8% respectively. With coconut fiber M-sand concrete, the ratio of compressive to flexural strengths is at its highest, 0.31.
