Testing of Bond Behavior of UHPC

Abstract:

Outstanding features of UHPC - Ultra High Performance Concrete are generally known. It has become increasingly used worldwide. For a better understanding of the material some features like the bond of reinforcement and UHPC has to be quantified. Research is focused on determination the bond stress between two types of the reinforcement (prestressing strands and bars) and different types of UHPC. Main goal of the research is to show significant increase in the shear stress in bond of UHPC compared to ordinary concrete. For evaluation of the bond stress the pull-out test were carried out. Specimens were prepared according to standard and tested in the laboratory. The influence of different material properties and different anchorage length of reinforcement to bond behaviour was examined.
