Abstract: Natural fibers such as coir, jute, and bamboo are renewable resources that offer high tensile strength and low environmental impact compared to traditional synthetic fibers. The study aims to determine the effects of different proportions of natural coconut fiber on the compressive strength of concrete. This research contributes to developing eco-friendly concrete materials that can reduce the construction industry's carbon footprint while maintaining structural integrity. Moreover, using natural fibers offers ecological advantages by reducing the reliance on non-renewable resources and lowering the carbon footprint of concrete production. The results indicate that adding natural fibers improves the toughness and crack resistance of concrete, making it a viable alternative for sustainable construction practices. The compressive strength test of concrete cubes incorporating artificial fiber named recron in the same proportion as natural fiber was also performed to compare the results.

Keywords: Natural coconut fibers, Compressive strength, Crack resistance, Sustainable Construction practices, Artificial reconfiber.
