Jayamanne, B.C.D.Velauthapillai, S2023-11-132023-11-132023-03-252961-5011https://rda.sliit.lk/handle/123456789/3579Even though the building industry is modernizing in terms of technology and materials used, construction costs have risen, as has the environmental impact. The behavior of coconut fiber in a concrete structure is described in this paper. Coconut fiber increases a range of technical qualities in concrete. Sustainability is a generally accepted concept in today's construction industry. Coconut fibers have the highest tenacity of any natural fiber. They can be used for reinforcement in low-cost, basic concrete structures. The experiment will be conducted out on concrete with fibre inclusion in four different mix proportions (0%, 2%, 4%, and 6% by weight of the cement). This experiment will assess the compressive strength and split tensile strength of coconut fiber-reinforced concrete after 7 and 28 days. This test is sufficient for M20 and M30 grade concrete. According to this study, CFRC with a fiber fraction of 2% had the best Split Tensile Strength. Additionally, adding coconut fibers reduces the compressive strength of concrete.enCFRCCoconut FibreCompressive StrengthSplit Tensile StrengthArticlehttps://doi.org/10.54389/YVZT5486
