TENSILE STRENGTH OF STEEL FIBER REINFORCED CONCRETE: CORRELATION WITH SOME MEASURES OF FIBER SPACING

A comparative study was performed on the degree of correlation between the measured direct tensile strength of steel fiber reinforced concrete and expressions relating the spacing of fibers to tensile strength in concrete. These included two conventional expressions for average fiber spacing and an expression for the number of fibers per unit cross-sectional area. The results indicated that the tensile strength test results correlate better with the expressions considering number of fibers per unit area as compared with the conventional fiber spacing expressions. Duoform and straight fibers, when used at similar number per unit cross-sectional area in concrete, were also found to produce statistically comparable improvements in direct tensile strength of concrete.
