    Shotcrete

State-of-the-art solution for shotcrete applications

Steel fibre reinforced concrete for shotcrete applications allows the use of both dry and wet shotcreting methods.

Numerous advantages

  • Easy user-friendly handling / faster application
  • Substantial material savings
  • Less rebound and voids
  • Excellent ductility and durability
  • Safer working environment through the use of shotcreting robots

Typical fibre dosage rates for shotcrete applications are between 25 and 50 kg/m³ depending on the fibre type and the required performance. Shotcrete fibres are generally shorter and thinner than other fibres.

ArcelorMittal proposes a full range of dosing equipment for adding the shotcrete fibres to the concrete and assists our customers various aptitude tests for characterizing the chosen steel fibre reinforced concrete for shotcrete applications.
