Experimental and numerical investigations of the flexural behaviour ‎of Green - Ultra High Performance Fiber Reinforced Concrete ‎beams under repeated loads

There are various benefits to ultra-high-performance fiber-reinforced concrete ‎‎(UHPFRC). However, using a lot of cement in this type has severe disadvantage since it causes pollution and several environmental concerns. Therefore, another that achieves the same superior properties as UHPFRC while less mixture should be considered. This research examined replacing with fly ash produce environmentally friendly called Green-UHPFRC. The impact utilizing G-UHPFRC on flexural behaviour thirteen beams was investigated experimentally numerically under repeated loads. major parameters study were replacement ratios 15%, 30%, 45% adding steel fiber mixes 1, 2, 3, 4%. tested compared control beam their backbone hysteresis curves, failure load, crack propagation modes, energy dissipation, stiffness degradation, ductility index. From results obtained, (G-UHPFRC) can produced by up 2% without affecting bending performance made those UHPFRC.
