Abstract: Agro-waste can be used as raw materials for manufacturing various products after recycling. Different researches have investigated the usefulness of coconut fibers (coir) as a micro-reinforcement in concrete this research is aimed at determining properties of fresh and hardened concrete from Ordinary Portland Cement (OPC) reinforced with coconut fiber (coir) and super plasticizer admixture in the form of liquid soap. The flexural and compressive strength of the Coconut Fiber Reinforced Concrete (CRFC) were evaluated at varying percentages (0.1, 0.3 and 0.5% by weight of cement) of fiber. The optimal percentage of fiber for both compressive and flexural strength was determined. It is observed that, there is an increment in the various properties and strength of concrete by the addition of fiber as reinforcement, up to an optimum percentage where the strength starts to drop. The flexural strength was seen to increase considerably by about 17.6% while the compressive strength improved by 23%.
