Impact Resistance of Coconut Fibre-Reinforced Concrete

Abstract

Concrete is often subjected to impact loads which reduces its service life. Natural fibres like coconut fibre have certain mechanical and physical properties that can be used to reinforce concrete against such loads. This study used the Charpy impact test to determine the impact resistance of different mix ratios of coconut shell fibre-reinforced concrete. The result revealed that a 3% inclusion of coconut fibre significantly enhanced the material's ability to withstand impact loads. The optimal proportion for maximizing impact resistance was identified as 3%. Concrete samples with a 1:1:2 mix ratio exhibited increased energy absorption capacity, emphasizing the impact of mix proportions on the material resistance to impact.
