Interaction of concrete beams with hybrid fibers under cyclic loading

The unique type of concrete that is most frequently employed is fiber reinforced concrete. Typically, only one fiber is utilized in fiber-reinforced concrete. This research primarily focuses upon the influence of fiber on its addition to concrete. In this study, bending behavior of fiber-reinforced concrete beams under cyclic pressure is investigated using hybridized polypropylene and steel fibers. There have been six different mixtures created, one of which being regular concrete. Monofilaments have been prepared from equal composition of steel and polypropylene with 0.5%. Apart from that hybridized combinations were also prepared using 0.12% steel fiber and 0.38% polypropylene fiber, 0.12% steel fiber and 0.38% polypropylene fiber, and 0.12% steel fiber and 0.38% polypropylene fiber. Superior flexural properties were observed with hybridized mix combinations ensured through experimental and numerical studies.
