Experimental study and prediction of tensile strength for steel fiber reinforced concrete

Results of an investigation conducted to study the tensile strength of steel fibre reinforced concrete (SFRC) containing fibres of 0%, 1%, 2% and 3% volume fraction of Hook tain steel fibres of 50, 60 and 67 aspect ratio are presented. Cylinder specimens of size 150 mm diameter and 300 mm length were tested under compression testing machine as per I.S. 516–1959. A result data obtained has been analyzed and compared with control beam (0% fibres). A relationship aspect ratio vs. Tensile strength represented graphically and governing equation of graphs and prepared Mathematical model for Tensile strength can be used to predict Tensile strength of SFRC by using appropriate values of percentage of fibers (V_f) and aspect ratio (A).
