(former MasterFiber® 154)

Polypropylene macro fiber for use in concrete

Polypropylene macro fiber for use in concrete

  • Improves the ductility of concrete.
  • Transfers tensile stresses and bridges cracks in cementitious applications.
  • Decreases crack propensity due to constrained deformations induced by drying shrinkage and temperature gradients and allows to partially or fully substitute related mesh reinforcement .
  • Excellent resistance in alkaline and acidic environment.
  • Provides rust free reinforcing solutions.
  • Easy to dose with limited impact on workability.
  • Safe to handle.
  • No negative impact regarding machinery wear.

DOSING AND MIXING
Appropriate fibre dispersion can be achieved either by adding the fibres to the aggregate belt or by adding the fibres via a sufficient dosing equipment directly into the mixer or ready-mix truck to the already mixed concrete. While processing attention shall be paid that fibres do not separate or agglomerate (e.g. during discharge to mixer), regarding the latter one special care should be taken that fibres are added to zones with sufficient shear. Our recommendation is to continue mixing for minimum 90-120 seconds after the addition of fibres. Very high fibre dosages may require significantly higher mixing time in order to achieve sufficient fibre dispersion.


ADVICE
The addition of fibres to a concrete might decrease its consistency. This should not be compensated by adding water to the mix. The recommendation is to optimize the mix either by adapting the mix design or by adding a superplasticizer. The mechanical performance of fibres is influenced by the concrete mix design and cementitious materials used. In order to evaluate properly preliminary tests under practical conditions with regard to mixing, placing and curing are advisable. For any further advice, please contact your local technical sales contact.


COMBINATION
Because of its inert nature, this fibre is combinable with all products of the Sika product range. As generally recommended also for combination of this fiber with SikaControl AER products, initial and identity testing should be performed.

Recommended Dosage

2.5 – 8.0 kg/m3 Higher dosages are generally possible but substantial redesign of a given concrete mix design is required.
