The use of Polyethylene Terephthalate (PET) fiber-reinforced concrete (PFRC) has gained significant attention as a sustainable and performance-enhancing alternative in modern construction. This study investigates the load distribution characteristics and environmental performance of PFRC by incorporating recycled PET fibers into concrete mixtures. The research evaluates the influence of PET fibers on compressive strength, flexural behavior, toughness, and crack resistance, utilizing experimental testing and numerical simulations. A comparative analysis with conventional concrete highlights improvements in load transfer efficiency, ductility, and post-crack behavior.

In addition to mechanical performance, the environmental impact of PFRC is assessed using life cycle analysis (LCA), focusing on carbon footprint reduction, energy savings, and waste management benefits associated with repurposed PET fibers. Results indicate that the incorporation of PET fibers enhances durability while reducing the overall ecological footprint, making PFRC a viable solution for sustainable infrastructure development. The study concludes that PET fiber reinforcement improves both structural resilience and environmental sustainability, offering a promising direction for future construction materials.
