Hooked Flat End fibres – HFE
A combination of HE (Hooked End) and FE (Flat End) shapes.
Hooked-Flat-End fibres are a combination of the HE (hooked end) and the FE (flat end) shape. By flattening the extremities of the crimped fibres, the anchorage capacities are still improved, especially for small strains. HFE fibres can be used in any type of application.
The workability of HFE fibres is excellent up to aspect ratios of 80 even when using high dosage rates up to 80 kg/m³. HFE fibres show excellent static performance and shrinkage control in fresh and in hardened concrete. As with the HE shape, all concrete grades can be used with the HFE shape.
ArcelorMittal HFE fibres are currently available in a single size.
