Abstract
A steel fiber for reinforcing concrete or mortar comprises a middle portion and an anchorage end at one or both ends of the middle portion. The middle portion has a main axis. The anchorage end is deflecting from the main axis of the middle portion in a deflection section. The anchorage end has n bent sections, with n equal or larger than 2. The steel fiber is configured so that when the steel fiber is in a stable position on a horizontal surface being vertically projected on this horizontal surface, the vertical projections in this horizontal surface of all of the n bent sections of an anchorage end are located at one side of the vertical projection in this horizontal surface of the main axis of the middle portion.
