Fiber-reinforced concrete (FRC) enhances the mechanical properties of traditional concrete by integrating various types of fibers, resulting in improved toughness, ductility, and crack resistance. The performance of FRC is influenced by fiber type, volume, and orientation, along with mix design considerations. Advances in technology have led to the development of specialized composites and hybrid systems that optimize the advantages of fiber integration.
