Steel Fibre Reinforced Concrete and Pavements: A Review

Fibres had been used as a reinforcing material since ancient times. They help in providing sufficient strength to composites. Steel fibres have proved their significance in modern civil engineering. Although these can’t replace steel completely as a tension providing material but they are able to perform quite well as reinforcing material plus they have some additional properties that steel don’t. For example, steel fibre wires can be laid along any alignment inside a structural component. Now a days achieving more strength along with greater economy in projects is considered as smart work. Those days are gone when it was assuming that with having large dimensions, structures possess great strength. Now higher strengths can be achieved along with having less thicknesses and depths of structures or pavements. Adding steel fibres is one of the methods of achieving good strengths in structures which are subjected to high impact loads. They can be provided with curvy paths which help in providing more stiffness to the concrete and helps in holding it together even when it is cracked. The best application of steel fibres is put in the pavements. Steel fibres are of great use in pavements and in this paper the characteristic properties of steel fibre reinforced concrete in pavements are discussed.
