Sažetak
In this paper, the effect of different type of fibers on mechanical properties of concrete was analyzed. For this purpose, steel fibers with different volume fraction of polypropylene fibers are used. The results show that concrete reinforced only with steel fibers gives the highest compressive strength, while the compressive strength of hybrid fiber reinforced concrete decreases with the increase of volume fraction of polypropylene fibers in comparison to the reference concrete. On the other hand, hybrid concrete with combination of steel fibers and 0.1% volume fraction of polypropylene fibers shows the highest bending tensile strength.
