Abstract

Polypropylene, a widely used thermoplastic, has become a major contributor to environmental waste due to its extensive production and the gradual degradation of its fibres. To address this critical issue, a comprehensive study was undertaken to investigate the impact of polypropylene fibre reinforcement in mortar. The study involved a battery of tests designed to evaluate the effectiveness of this approach. Results indicated that the optimal percentage of polypropylene fibres for achieving maximum compressive strength after 7 and 28 days was found to be 0.4%. This percentage performed best within a specific water-to-cement ratio (w/c) range of 0.6 to 0.8. Additionally, the research revealed that the most effective combination for enhancing flexural strength was a water-to-cement ratio (w/c) in the range of 0.6 to 0.8, along with a 0.6% polypropylene fibre content. It's worth noting that this innovative technique not only promises to bolster the strength characteristics of mortar but also offers a sustainable solution by reducing the environmental burden associated with polypropylene waste. These findings have significant implications for achieving commercial and engineering goals while addressing the limitations of traditional mortar practices. In summary, the study offers a promising path toward enhanced construction materials and reduced environmental impact.
