摘要

This paper outlines the experimental programme and its results on the bond performance of conventional rebars in steel fibre reinforced normal strength concrete (NSC) and high strength concrete (HSC). The two main tasks were the time development of the bond properties and the influence of fibres on bond. So, the hardened concrete properties and the bond behaviour were experimentally investigated at 3 and 28 days and collated with plain concrete. One of the main conclusions is that steel fibres reduce the risk of splitting of the concrete cover. Also the ductility of the bond is enlarged.
