An experimental study of the bond between ultra-high-performance steel-fibre reinforced concrete (UHPSFRC) cast upon glass-fibre reinforced polymer (GFRP) sheets, as well as of the bond between epoxy-jointed precast UHPSFRC sheets, has been conducted at Chalmers University of Technology. Both shear and tension tests have been performed. Several surface treatments of the different interfaces have been tested. For the joint interface between UHPSFRC and GFRP the best performance was found for a surface with double-bent steel fibres added to epoxy overspread with sand coating, which were allowed to harden prior to casting the concrete. For the epoxy-jointed concrete sheets the best performance was found for a surface where the smooth 'formwork side' was sand-blasted before the epoxy gluing. However, it was concluded that more testing is needed before decisive recommendations can be made. In addition, materials tests of the UHPSFRC have been conducted in both tension and compression.
