Enhancing Durability and Crack Resistance of Concrete using Coconut Fibre

The increasing demand for sustainable and eco-friendly construction materials has led to the exploration of natural fibers as reinforcement in concrete. This study investigates the potential of coconut fiber, a readily available agricultural waste product, in enhancing the mechanical properties of concrete. Coconut fiber, known for its high toughness, low density, and biodegradability, was incorporated into concrete mixes in varying percentages by weight of cement. Experimental results revealed that the addition of coconut fibers improved the tensile and flexural strength of concrete, while also enhancing crack resistance and durability. However, an optimal fiber content was identified, beyond which the workability and compressive strength began to decline due to fiber agglomeration and poor bonding. This research highlights the feasibility of using coconut fiber as a sustainable and cost-effective reinforcement material, promoting the development of greener construction practices without significantly compromising the performance of concrete.
