The benefits of using steel fibres in concrete are as follows: 1. Steel Fibres are generally distributed throughout a given cross section whereas reinforcing bars or wires are placed only where required 2. Steel fibres are relatively short and closely spaced as compared with countinuous reinforcing bars of wires.

The size of movement depends upon the change in temperature and the coefficient of thermal expansion o f concrete. The coefficient of thermal expansion of concrete is influenced largely by the coefficient of thermal expansion of the aggregates since the aggregate occupies 70-80% of the volume of the concrete.

Upon wetting, concrete tends to expand. This type of shrinkage is caused by the loss of moisture from the cement paste constituent, which can shrink by as much as 1% per unit length. Unfortunately, aggregate provides internal restraint that reduces the magnitude of this volume change to about 0.05%.

The stress strain curve of concrete lies between those of the aggregate and the cement paste. The aggregate is more rigid than the cement paste and will therefore deform less (i.e. have a lower strain) under the same applied stress.
