Fiber-reinforced concrete (FRC) is concrete that has fibers added to improve its tensile strength. Finer fibers below 0.5mm in diameter are more effective at improving flexural strength and ductility. FRC exhibits higher flexural strength and strain capacity than plain concrete, allowing it to withstand cracking and greater deflections under bending loads. FRC is often used in thin structural elements like shells, walls, pipes and manholes that experience flexural stresses.
