The main objectives of this study are to determine the influence of concrete mix composition on steel fiber reinforced concrete SFRC properties.For the range of aggregate maximum size used (1/4” -1”), the ultimate flexural strength was found to be independent of maximum aggregate size. The fine aggregate needed in the mix is a function of the volume and type of fibers. Mixes with medium and high fine aggregate content (55 to 75%) showed the best results with respect to workability and strength. The influence of fibers in increasing ultimate flexural strength was the greatest when low or medium water cement ratio was used (0.42 or 0.51). The ultimate flexural strength was found to be approximately proportional to the fiber concentration in the concrete.
