TO INVESTIGATE COMBINED INFLUENCE OF STEEL FIBER AND SILICAFUME ON HIGH STRENGTH CONCRETE RIGID PAVEMENT

Fibres are generally mixed with concrete to enhance the resistance of cracking and strengthening of concrete. In this project, tests w ere carried out on steel fibre reinforced concrete to check the influence of fibres and silica fume on flexural strength of concrete. According to various research papers, it has been found that addition of steel fibres and silica fume enhances the strength of the concrete. In this project practical tests we re carried out to find out optimum quantity of steel fibres required to achieve the maximum flexural strength for higher grades of concrete.
