The uses of steel fiber in concrete can improve its many properties. The benefits of using Steel fibers in concrete are as follows:
1. Steel fibers are generally distributed throughout a given cross-section, whereas reinforcing bars or wires are placed only where required.
2. Steel fibers are relatively short and closely spaced as compared with continuous reinforcing bars of wires.
3. It is generally not possible to achieve the same area of reinforcement to an area of concrete using steel fibers as compared to using a network of reinforcing bars of wires.
4. Steel fibers are typically added to concrete in low volume dosages (often less than 1%), and be effective in reducing plastic shrinkage cracking.
5. Steel fibers typically do not significantly alter free shrinkage of concrete, however, at high enough dosages they can increase the resistance to cracking and decrease crack width.
