Abstract

Use of fiber reinforced concrete is increasing recently, brought forth by the enhancements of concrete matrix engineering properties upon adding fiber. The resulting material possesses higher tensile strength, consolidated response and better ductility, which ultimately minimize immature failures. Thus it is beneficial to comprehend more the engineering properties of the material. Accordingly, this study moves toward deriving a mathematical expression that relates fiber reinforced concrete compressive strength to split cylinder tensile strength. Literature survey is carried out to collect data, pertinent to split cylinder tensile strength versus compressive strength values, for fiber reinforced concrete. Gathered data comprise compressive strengths from 20 MPa to 102 MPa. Regression analysis is performed; a mathematical expression that predicts split cylinder tensile strength of steel fiber reinforced concrete is eventually derived. The predicted values fit well with experimental data. The findings of this study shed more light on the tensile strength of fiber reinforced concrete.
