Abstract:

 The paper presents the results of an investigation conducted to study the influence of fiber hybridization on the compressive strength, flexural strength, flexural fatigue and flexural toughness of the Hybrid Fiber Reinforced Self Compacting Concrete (HyFRSCC). The Steel Fibers (SF) and Polypropylene Fibers (PPF) at 1% by volume of concrete have been used. The PPF and SF proportions used are 100% PPF, 75% PPF + 25% SF, 50% PPF + 50% SF, 25% PPF + 75% SF and 100% SF. The flexural toughness parameters were calculated using procedure laid down in JCI Method,  ASTM C-1018 C and ASTM 1609/C 1609 M. The flexural fatigue tests were conducted at stress levels of 0.65, 0.7, 0.75, 0.8, 0.85 and 0.9. The Weibull parameters have been calculated using the graphical method and the method of moments. The results indicate that the mix with a fiber combination of 25% PPF + 75% SF can be adjudged as the optimum combination for HyFRSCC in terms of compressive strength, flexural strength and flexural toughness. Gradual replacement of steel fibers with polypropylene fibers has been found to reduce the variability in fatigue life data of HyFRSCC.
