Crack control, post-cracking tensile behavior, ductility and a less sensitive concrete surface are just some of the positive material properties of steel fibre-reinforced concrete. For years, steel fibres from KrampeHarex® have been used to support projects such as the "Stormwater System" in Dubai, setting an international trend.
In the construction of the 10.2 km long "Stormwater" tunnel in Dubai, KrampeHarex® participated by supplying 5,000t of fibres for 43,000 tunnel lining segments manufactured on site. The use of cold-drawn wire fibres type DE 60/0.9 H with a tensile strength of 1,900 N/mm² ensures optimum stability and durability of the concrete used.
Fibres – Made in Germany
In this project and in many others, the focus is on both: reliable delivery and the positive material properties of the fibres. To ensure fast and timely delivery, the wire of KrampeHarex® steel fibres is drawn in-house and tailored to the individual requirements of the project - in terms of tensile strength, length, fibre geometry and to match the optimum economical fibre content.
- concrete surface less sensitive to crack control
- easy mixing and dosing of the fibres due to flexible dosing systems
- faster completion
- increased durability and service life
Steel fibre reinforced concrete has a higher durability than conventionally reinforced concrete. The distribution, shape and type of the fibres make the concrete more resistant and fatigue-resistant too. In addition, the steel fibres are easy to work with - without balling, floating or settling. We have the right fibre for all applications: precast concrete, shotcrete, tunneling, industrial flooring, logistics areas, residential construction, etc
