Behavior of Steel Fiber Recycled Coarse Aggregate Reinforced Concrete Subjected to Direct Shear

Abstract

The behavior of steel fiber recycled coarse aggregate reinforced concrete (SFRCA) subjected to direct shear was investigated by this study. The results of twenty four push-off reinforced concrete specimens are presented and analyzed. The studied parameters are the steel fiber volume fraction (Vf ) and the recycled coarse aggregate replacement ratio (RCA). Three steel fiber volume fractions are used (0%, 0.5%, and 1%) and four RCA replacement ratios are used ( 0% , 25% , 50% , and 100% ). The test results show that the steel fiber is an effective alternative material for enhancement of the shear strength of recycled coarse aggregate concrete.
