MasterFiber 252 SPA

High Performance Structural Synthetic Fibre for Reinforcement in Cast and Sprayed Concrete Applications as an Alternative and/or Supplement to Existing Concrete Reinforcement Products

How Does MasterFiber 252 Work?

MasterFiber 252 SPA is engineered for use as secondary reinforcement to control shrinkage, temperature, and settlement cracking.
MasterFiber 252 SPA is an option for the replacement or supplementation of steel mesh reinforcement and is an easy-to-use secondary reinforcement system that is rust proof and alkali resistant.
MasterFiber 252 SPA conforms to the requirements of EN 14889.2 Class II.

Areas of Application

MasterFiber 252 SPA applications include, but are not limited to:

• Slabs on ground: footpaths, shared user paths, industrial floors, hardstands, and mine haul roads

• Precast: Pits, troughs, tanks, and panels

• Shotcrete: Ground support for tunnels, mines, and civil slope stabilisation

What are the Benefits or MasterFiber 252 SPA?

• Allows for full or partial substitution of steel mesh reinforcement

• Reduces labour, construction, transport, and storage costs compared to a solution with conventional reinforcement

• Bridges cracks and transfers tensile stresses in cementitious applications

• Improves concrete ductility and high energy absorption

• Provides increased flexural toughness to the concrete and decreases crack occurrence due to constrained deformation and impact

• Enables carbon reduction within the concrete element

• Provides a rust free reinforcing solution

• Excellent resistance in alkaline and acidic environments

• Easy to dose either at the batch plant or on site concrete mixer truck prior to application

• Safe to handle and no negative impacts on machinery wear
