Fiber Reinforcement in Concrete: A Literature Review

This literature review paper explores the multifaceted role of fibers in concrete, emphasizing their types, mechanisms of reinforcement, advantages, disadvantages, and alignment with sustainable development goals. Various fibers, including steel, polypropylene, carbon, basalt, glass, and natural fibers, are examined for their impact on concrete’s mechanical properties and durability. The review highlights how fibers enhance tensile strength, reduce cracking, and improve ductility, thus addressing the inherent brittleness of conventional concrete. Additionally, the paper discusses the economic implications through life cycle cost analysis (LCCA), revealing that while initial costs may be higher, long-term savings in maintenance can offset these expenses. The environmental impact is assessed through life cycle assessment (LCA), indicating that fiber-reinforced concrete can lead to lower carbon emissions and resource depletion compared to traditional methods. Furthermore, the review identifies research gaps, particularly in the long-term performance of hybrid fiber systems and the economic viability of natural fibers. Future trends are anticipated to focus on the development of innovative fiber materials and hybrid systems that optimize performance while promoting sustainability. This comprehensive analysis underscores the importance of integrating fibers into concrete to enhance structural performance and align with global sustainability initiatives, paving the way for more resilient infrastructure in the future.
