Fibre Reinforced Concrete (FRC) is the mixture of conventional concrete and the fibres like steel, glass, polypropylene, nylon, carbon, polyethylene, polyester, jute etc. When steel and polypropylene fibres are mixed in the Concrete, it is known as Steel-Polypropylene Fibre Reinforced Concrete(SPFRC). Concrete layer requires adequate strength and durability to resist the actions of traffic; it also must be able to provide adequate bending resistance for distribution of load, and have adequate skid characteristics to resist the abrasive forces of traffic; SPFRC with higher flexural strength characteristics, compressive strength characteristics, toughness and resistance to fatigue, is needed for  layer. SPFRC has been used to provide durable concrete  layer with improved cracking resistance and reduction in the required slab thickness.

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. Reinforcing the concrete structures with fibres 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 Fibre Reinforcement of Concrete Structures. There is an increasing worldwide interest in utilizing fibre reinforced concrete structures for civil infrastructure applications. The bonding between the fibres and the concrete has to be good and the plastic has to withstand the changing environment of freeze and thaw as well as a high PH of 12.5 and a low of PH 6.5 when saturated with sodium chloride.

Concrete is most widely used construction material all over the world in respect of its strength, durability, high mould ability, stability and relative low cost. Rapid advances in construction technology have enabled civil and structural engineers to achieve impressive gains in functionality of structure built to serve the common needs of society. The use of fibres in concrete will increasingly continue to be the preferred choice for many repair and rehabilitation projects involving construction of bridges, Industrial floors, airport pavements, overlays, high rise buildings, towers, parking garages, offshore structures, historic monuments etc.
