Abstract:This paper represents the results of an extensive experimental program that was carried out on steel fibre high strength concrete. The influence of volumetric ratio of fibre (Vf) on the different structural properties of steel fibre high strength concrete is investigated in this study. The properties include compressive strength, splitting tensile strength, stress-strain behavior, and modulus of elasticity. Control mixes of plain concrete that cover a wide range of high strength concrete, specifically from 40 MPa up to 80 MPa specified strengths, are first prepared. Then, steel fibres of different volumetric ratios ( 0.5 %, 0.75 %, 1.0 %, and 1.5 %) were used with the control mixes to establish their effect on the structural properties. The results showed that the addition of steel fibres to the concrete mix of high strength concrete enhanced the different properties especially splitting tensile strength and stress-strain behavior. The performance proved to be better for higher volumetric ratio of the steel fibre. Regression analyses are carried out and derived relations for different structural properties are compared with those in the ACI Codes.
