Abstract

Fiber-reinforced concrete (FRC) has emerged as a significant advancement in construction materials, offering enhanced mechanical properties and durability compared to conventional concrete. This paper comprehensively reviews the effects of various fiber types on the strength and durability characteristics of concrete. The study examines steel, synthetic, glass, and natural fibers, analyzing their impact on compressive strength, tensile strength, flexural strength, crack resistance, and long-term durability. Through analysis of experimental data and field applications, this research demonstrates that fiber reinforcement significantly improves concrete performance, particularly in controlling crack propagation, enhancing ductility, and improving resistance to environmental degradation. The findings indicate that optimal fiber content varies between 0.5% to 2.0% by volume depending on fiber type and application requirements.
