Optimizing Mechanical Properties of Polypropylene Fibre-Reinforced Coconut Shell Concrete
Abstract: This study investigates the impact of polypropylene (PP) fibre reinforcement on the mechanical properties of coconut shell (CS) concrete. The compressive strength of CS concrete is primarily governed by the strength of CS aggregates, with early-age failure attributed to poor bonding and later-stage failure influenced by aggregate strength. The incorporation of PP fibres significantly enhanced compressive, tensile, and flexural strength. At 28 days, compressive strength increased by 1.2–3.45% in CSF …
