Abstract	this study, the potential of using coconut shell as coarse aggregate replacement and coconut fiber as reinforcement in M 25 grade concrete with a water to cement ratio of 0.45 is examined. The goal is to create a sustainable, environmentally friendly and cost-efficient building material.Experiments were performed to investigate the compressive, split tensile and flexural strengths of the concrete after 7 and 28 days of curing. Researchers are looking on substitute materials that lessen their impact on the environment without sacrificing structural integrity as a result of the growing demand for environmentally friendly and sustainable building materials. The effects of using coconut fiber as a reinforcing agent and coconut shell as a partial substitute for coarse aggregates in concrete mix design are examined in this study. Coconut fiber, which is made from the husk of the coconut, improves the tensile strength and crack resistance of concrete, while coconut shell, an agricultural waste product, provides a lightweight and sustainable substitute for traditional aggregates. This study investigates the performance of Mix grade concrete with respect to workability and mechanical strength for practical construction applications. The slump values obtained were within the desirable range, indicating adequate workability suitable for slab and beam casting in residential buildings. Experimental results show a positive relationship between compressive strength and both flexural and split tensile strengths, confirming overall strength enhancement with increasing compressive strength. The improved homogeneity and reduced bleeding contributed to better surface integrity and crack resistance. Based on the observed strength characteristics and workability, the developed concrete mix is found to be suitable for house construction as well as for road and pavement applications. The study demonstrates that an optimized mix design can effectively balance workability and strength requirements, ensuring reliable structural performance
