This research paper reports the effect of natural fiber content on the physical and mechanical properties as well as fracture behavior of composite cement reinforced with coconut fiber. The mix design was based on 1:1 for cement:sand ratio and 0.55 was fixed for amount of water per cement ratio. Coconut fiber was added as reinforcement and replacing the composition of sand. Composites were developed based on 3 wt. %, 6 wt. %, 9 wt. %, 12 wt. % and 15 wt. % of coconut fiber by mixing and curing process. Composites were cured in water for 7, 14, and 28 days. It was observed that the composite reinforced with 9 wt. % of coconut fiber demonstrated the highest strength of modulus of rupture and compressive strength. Results of density, water absorption and moisture content are also presented.
