摘要：

This paper investigates the flexural fatigue behavior of Self Compacting Rubberized Concrete (SCRC) with and without steel fibers. The variables included in this study were different values of replacement of fine aggregate by shredded rubber, viz. 15% and 20% and volume fraction of steel fibers, viz. 0.5% and 0.75%. A total of 60 prism specimens were tested under fatigue loading considering maximum stress levels ranging from 90% to 60% of the static strength. The results show significant improvement of 15% and 25% in the fatigue performance of SCRC and Steel Fiber Reinforced SCRC (SFRSCRC) when compared to Self Compacting Concrete (SCC). Also, the probabilistic distribution of fatigue life of SCRC and SFRSCRC at a given stress level has been approximately modeled by the two-parameter Weibull distribution. (C) 2013 Elsevier Ltd.
