Hooked end fibre
The most popular and successful shape
Hooked end fibre has been in the market for over 25 years. This shape is probably the most popular and successful in the history of steel fibre reinforced concrete. This is due to the fact that over the last decade almost all fibre manufacturers have added the hooked end shape to their product range.
HE can be used in almost any known application for steel fibre reinforced concrete. For example, ArcelorMittal’s HE 55/35 and HE 75/35 are primarily used in shotcrete applications.
HE does not perform as well as undulated fibres with regard to shrinkage control but it provides excellent workability when using fibres with up to an aspect ratio of 60. Aspect ratios up to and including 80 provide satisfactory workability.
HE can be used with any concrete mix and high concrete density is less mandatory then for undulated or for flat-end fibres. Load transfer in the crack is very good with this fibre shape. Thus after the appearance of the first crack the loss of load-bearing capacity occurs quickly but then stabilizes and in some cases even begins to increase again after large cracks have developed.
