AN INVESTIGATION INTO THE USE OF FIBRES IN CONCRETE ...

Currently, the use of fibres in concrete, while growing, is not as widespread as its mechanical advantages would suggest it should be. A possible reason for this is the natural hesitancy of engineers and practitioners to use a material for which adequate; experience, experimental data and code provisions have not been well developed.

Fig 2: Steel Fibres 1.3 Need of Fibres in SCC Self compacting concrete develops micro cracks with curing and these cracks propagate rapidly under applied stress resulting in low tensile strength of concrete. Hence addition of fibres improves the strength of concrete and these problems can be overcome by use of glass fibres in concrete.
