Because significant difference between normal concrete and fiber reinforced ultra-high strength concrete under tension and compression, bond behavior also have significant difference. Bond behavior may affect to the flexural behavior and shear behavior of reinforced concrete beams. Especially, because ultra high strength concrete usually be used as precast members, bond between concrete and steel rebar should be safely and accurately evaluated for design. In this study, bond test results about ultra high strength fiber reinforced concrete were investigated and evaluated with various types of prediction methods, especially for empirical equations.
