Zusammenfassung:The invention relates to a steel fibre for reinforcing concrete or mortar. The fibre has a middle portion and anchorage ends. The middle portion has a maximum load capacity Fm and an elongation at maximum load Ag+e. The elongation at maximum load Ag+e is at least 2.5%. The steel fibre has an anchorage force in said concrete or said mortar of at least 90% of the maximum load capacity Fm. The anchorage force is the maximum load obtained during a pull out test of a steel fibre embedded with one of the anchorage ends in the concrete or the mortar. The steel fibre has the advantage that it can be used at normal dosages in load carrying structures of concrete.
