Product Specification

Steel Fiber CR 30

Shotcrete
Fibre Reinforcement can be used in either the dry or wet process shotcreting to increase the toughness, ductility and impact resistance of in-place shotcrete. There are cases where Fibre Reinforced Shotcrete can replace wire mesh or reinforcing steel. The advantages of doing so are:

Substantially less material is required because Fibre Reinforced Shotcrete follows the contours
Of the surface providing a uniform reinforced liner
Time and money is saved because using Fibre Reinforced Shotcrete eliminated the labour
Intensive and at times, unsafe mesh installation step, allowing for immediate application of Shotcrete after excavation
Higher quality in place shotcrete because shooting through wire mesh can be very difficult, resulting in honeycombing, poor consolidation, shadowing, embedded rebound and poor bond to the mesh.
Steel Fibre is discontinuous, so rebar or wire mesh corrosion is eliminated Compatile with all types of Portland cements. Portland cement admixtures and shotcrete mix designs.
