Abstract:The effect of steel fiber volume fraction on the flexural strength flexural rigidity, toughness, and ductility of reinforced concrete beams was evaluated. A total of twenty simply supported reinforced concrete beams were tested. Ten of the twentybeams were cured under controlled laboratory conditions and the other ten were cured under field conditions characterized by intense heat, low relative humidity, and large diurnal variations. Tests were carried out 28 or 90 days after casting. The study shows that the flexural strength flexural rigidity, toughness, and ductility are in direct proportion with the fiber content. It also shows that the enhancements in these engineering properties due to the steel fiber addition are not affected by the above described severe field conditions. Furthermore, inclusion of steel fibers in concrete helps, to some extent, in reducing adverse effects of the severe climatic conditions on the properties of concrete.
