SikaFiber®-012

(former MasterFiber® 012)

Monofilament polypropylene fibers for cementitious systems

SikaFiber®-012 is a high-performance monofilament polypropylene fibre developed as a crack controlling additive for concrete and mortar. SikaFiber®-012 is supplied agglomerated in flakes bound by a water-soluble adhesive.

  • 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.

Usage

SikaFiber®-012 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 ready-mix 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.
