Abstract

This paper furnishes the results obtained from the experimental investigation of mechanical characteristics of steel\nfiber reinforced high strength concrete blended with silica fume as mineral admixture. The various mechanical characteristics\nthat were studied by using the specimens like cube, cylinder and prism were cube compressive strength, split tensile strength\nand flexural strength of steel fiber reinforced high strength concrete of M60 grade. The study is confined to study the\nmechanical characteristics by using 7.5% silica fume as replacement to cement and also using steel and polypropylene fibers\nwith volume fractions of 1%, 1.5%, and 2% with variable percentages. Test results showed an improved mechanical\ncharacteristic of high concrete by the process of hybridization of fibers.
