Bond behavior between BFRP bar and recycled aggregate concrete reinforced with basalt fiber
HighlightsThe mechanical property tests and pull-out test of fibers RAC were conducted.Effect of fiber added on the bond stress-slip relationship was investigated.The strength of RAC was the main influence factor to the ultimate bond strength.Bond strength predictions from the equation compared well with the experimental results.
AbstractThis study investigated the effect on the bond behavior between BFRP bars and recycled aggregate concrete (RAC), which a total of 54 specimens for pull-out test and 162 specimens for mechanical properties were conducted. The parameters including RAC strength grade, chopped basalt fiber volume content and length, based on orthogonal test the bond stress-slip constitutive were proposed. According to the main results of experiment, the strength of RAC was higher than the other two factors in the effect of mechanical performance and ultimate bonding stress. Similarly, the influence of these factors on the free end slip that the length of chopped basalt fiber was the weakest, then the chopped basalt fiber volume percent was higher compared to RAC strength grade. Application of non-liner regression analysis in the bond stress-slip constitutive relationship with the experimental results and referred to the engineering practice.
