Comparative Study on Normal and Steel Fibre Reinforced Concrete

This study investigates the effects of addition of binding wires on the compressive strength of concrete. Different quantities of binding wires from 0-1.75% were added to the concrete to find out the optimum quantities of binding wires in which the FRC with binding wires is more effective in terms of strength and crack resistance capacity. Steel fibre reinforcement concrete (SFRC) is a composite material made of hydraulic cements, water, fine and coarse aggregate and dispersion of discontinues small fibres (steel fibre). It is one of the superior crack resisting building materials due to its ability to modify micro and macro cracking by intercepting cracks at their origin and inhibit crack growth. The study found that addition of steel fibre increased compressive strength at 7, 14, 28 days test. SFRC is a superior crack resisting building material due to its ability to modify micro and macro cracking by intercepting cracks at their origin and inhibit crack growth. The results of the study show that the addition of binding wires as fibre can significantly increase the compressive along with the crack arresting capacity. The results also give a detail idea of optimum quantity of steel fibre that can be used in concrete production to get better strength and at the same time it will be more economical.
