​​MasterFiber 12mm​ - Monofilament polypropylene fibres for cementitious systems​

Formerly Rheofiber 12mm

Description

MasterFiber 12mm is a high performance monofilament polypropylene fibre developed as a crack controlling additive for concrete and mortar. MasterFiber 12mm is supplied agglomerated in flakes bound by a water soluble adhesive.

Where is MasterFiber 12mm​applied?

  • MasterFiber 12mm is used to inhibit the formation of small cracks which can occur through plastic shrinkage and settlement, premature drying and early thermal changes, in order to provide utilisation of the intrinsic properties of the hardened cementitious material.
  • Specifically designed for crack control in cementitious materials covering areas such as readymix concrete, precast concrete, conventional shotcrete, screeds rendering mortars, etc.
  • Principle uses of fibre concrete include: concrete slabs, pavements, driveways, imprinted concrete, curbs, pipes, overlays patch repair, microsilica concrete, thin section walling, water retaining structures, marine concrete, heavy industrial floors etc.

What are the advantages of MasterFiber 12mm​?

  • Can replace anti-crack wire mesh in factory and warehouse floors
  • Inhibits intrinsic cracking in concrete
  • Disperse uniformly throughout the mix
  • Improves finishing characteristics
  • Improves concrete durability
  • Increases impact and abrasion resistance
  • Rustproof
  • Impervious to alkali attack
  • Decreases construction time and labour
  • Reduced risk of subsequent damage
  • Improves fire resistance – reduces the 
  • Incidence of explosive spalling during heating
