Abstract
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 Fand an elongation at maximum load A. The elongation at maximum load Ais 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 F. 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.
