Steel fibres offer state-of-the-art technology when used as reinforcement for concrete elements and in other applications.
All steel fibres manufactured by ArcelorMittal are produced from cold-drawn steel wire, using the latest high performance and most ecological technologies and CE certified (compliant with EN 14889-1). The steel fibre production is certified with ISO 9001, ISO 14001 and OHSAS 18001.
TABIX - Undulated fibre
TABIX is especially suited for jointless industrial floors and for structural applications. TABIX needs a well compacted medium to high strength concrete to develop its full performance.
Lengths: 35 to 60 mm
Diameters: 0.9 to 1.3 mm
Tensile wire strength: 900 to 1450 MPa
- Excellent shrinkage control
- Slower loss of bearing capacity immediately after the initial cracking, then most of the other fibre types on the market
- Higher pull-out resistance from the concrete matrix
HE - Hooked end fibre
On the market for over 25 years, the hooked end fibre the most popular and successful in the history of steel fibre reinforced concrete. 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 an aspect ratio of up to 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.
Length: 35 to 60 mm
Diameter: 0.55 to 1.00 mm
Tensile wire strength: 1100 to 1900 MPa
FE - Flat end fibre
FE is a straight fibre with flattened ends. It is sometimes referred to as fishtail. Through the flattening process, the ends become larger which significantly increases the anchorage of the fibre in the concrete matrix rather than relying solely on the friction between concrete and steel.
Today FE is almost exclusively used in shotcrete applications due to its low rebound ratio. This fibre can however also be used in other applications such as precast elements.
The workability of FE is excellent with aspect ratios up to 80. Flat-End fibre should not be used in applications where concrete shrinkage is a primary concern. In order to guarantee anchorage of the flattened ends, it is mandatory that a dense concrete mix with sufficient strength (minimum C 30/37) and fines content is used.
HFE - Hooked flat end fibres
HFE is a combination of the HE (hooked end) and the FE (flat end) shapes. By flattening the extremities of the crimped fibres, the anchorage capacities are still improved especially for small strains. HFE can be used in any type of application.
The workability of HFE is excellent up to aspect ratios of 80 even when using high dosage rates up to 80 kg/m³. HFE shows excellent static performance and shrinkage control in fresh and in hardened concrete. As with HE, all concrete grades can be used with HFE.
