     fiber reinforced concrete (frc) is a new structural material which is gaining increasing importance. addition of fiber reinforcement indiscrete form improves many engineering properties of concrete. deterioration of concrete structures due to steel corrosion is a matter of considerable concern since the repairing of these structures proved to be a costly process. repair and rehabilitation of the civil structures needs an enduring repair material. the ideal durable repair material should have low shrinkage, good thermal expansion, substantial modulus of elasticity, high tensile strength, improved fatigue and impact resistance. reinforcing the concrete structures with fibers such as polypropylene is one of the possible ways to provide all the criteria of the durable repair material. this type of reinforcement is called fiber reinforcement of concrete structures. there is an increasing worldwide interest in utilizing fiber reinforced concrete structures for civil infrastructure applications.the transformation from a brittle to a ductile type of material would increase substantially the energy absorption characteristics of the fibre composite and its ability to withstand repeatedly applied, shock or impact loading .this paper describes the different types of fibers and the application of frc in different areas. it also presents the mechanical properties and structural behavior of frc and developments done on fiber reinforced concrete.
