Abstract (en)

A steel fibre (10) for reinforcement of high-performance concrete or mortar has a length ranging from 3 mm to 30 mm, a thickness ranging from 0.08 mm to 0.30 mm, and a tensile strength greater than 2000 MPa. The steel fibre is provided with anchorages (12, 24) the dimension of which in a direction perpendicular to the longitudinal axis of the steel fibre is maximum 50 % of the thickness. These anchorages provide an effective staying in the high-performance concrete without influencing the mixability of the steel fibres in a negative way. <IMAGE>
