Polypropylene fibre (PPF) works as a reinforcement material, similar to incorporating strong fibres inside concrete matrices to boost structural stability. Widely employed in different fields such as automotive engineering, textile, geotextile and environmental conservation, PPF delivers great advantages due to its essential properties, including its lightweight nature, high strength and resistance to corrosion. The molecular arrangement of PPF, defined by combined propylene monomers forming linear chains, underlying its remarkable flexibility and tensile strength, rendering it significant in numerous applications. Nonetheless, gaps exist in our expertise, particularly concerning the study of higher thresholds: polypropylene fibre integration in concrete, workability reduction with increasing polypropylene fibre concentration, and the eco-friendliness of PPF. Further academic inquiry is important to construct sector-specific models for forecasting and maximising PPF concentrations in concrete compositions. These efforts show possibilities not simply for strengthening infrastructure but also for improving environmentally friendly materials science practices. This finding underscores the crucial relevance of further investigation in material utilizing scientific methods to fully use the capabilities of PPF in increasing structural resilience and environmental sustainability. Additionally, the review article provides insight into the present status of research on PPF, its manufacturing process and its uses in many sectors.
