Effect of fiber hybridization on mechanical properties of concrete

Abstract Ten concrete mixtures, using long and medium length hooked-end short wave-shaped steel fibers, were designed to experimentally investigate the effect of hybrid reinforcement on workability, drying shrinkage, mechanical properties fiber reinforced concrete. The fibers reduced workability shrinkage. Hybrid including fiber, can produce a synergistic compressive strength. For adopted materials, linear relationship was observed between shrinkage strain tensile splitting strength increased with volume fraction fibers. generated strength, an almost constant ratio tension use led higher modulus rupture, residual toughness than other mono Flexural increasing Residual varied hybridization. Overall, mix all considered had best performance among ones.
