Fiber Reinforced Concrete (FRC) which contains discrete steel, polymeric, or mineral fibers have been successfully used in a number of applications involving bridges, pavements, industrial floors, hydraulic structures, earthquake and blast-resistant structures. However, the full potential of FRC has not yet been explited. The practicing engineers need to be informed and educated about this composite to improve its utilization. At plastic stage, the fibers reduce the crack widths, thus providing improved durability. In the hardened stage, fibers provide improved ductility, tolerance to cracking, increase in fatigue strength and impact strength, and better permeability characteristics. Most of the improved properties relate to cracking and crack distribution. This paper summarizes the results available on the performance of fibers to improve cracking.
