Abstract
Micro steel fibres are currently added to UHPC to improve ductility. In UHPC under load, the high fibre strength is only utilised partly when the fibres are pulled out of the UHPC matrix. Using steel fibres with a nano- and micro-roughened surface is one measure to enhance the bond between the UHPC matrix and the fibre. In this contribution the effect of surface roughness on the bond behavior of steel fibres is shown. Single fibre pull-out tests were performed to investigate the bond behavior. Aim is to improve the bond behavior so that fibre pull-out takes place under a high load level with respect to the fibre strength.
