SikaFiber®-6 FF

Polypropylene fibres for concrete

SikaFiber®-6 FF is a polypropylene fibrillated fibre which reduces the occurrence of plastic shrinkage cracking and plastic settlement whilst enhancing the surface properties and the durability of the hardened cementitious product. The fibres are coated with surfactant to improve dispersion. SikaFiber®-6 FF is extremely fine and although slightly visible at the plastic stage, they are not readily seen on the hardened surface of the cementitious product.

APPLICATION INSTRUCTIONS

Mixing

The fibres should ideally be added in the mixer at the batching plant: although in some instances this may not be possible and adding the fibres on site will be the only option. If mixing at a dry batch plant, fibres should be the first constituent in the truck along with one third of the mixing water. After all the other ingredients have been added, including the remaining mixing water, the concrete should be mixed for a minimum of 70 revolutions at full speed to ensure uniform fibre dispersion.
 

Notes on Application / Limitations

  • When using SikaFiber®-6 FF a suitable mix design has to be taken into account and local material sources shall be trialled.
  • Support from our Technical Service Department is recommended.
  • SikaFiber®-6 FF should not be used to replace structural, load bearing reinforcement.
  • SikaFiber®-6 FF should not be used as a means of using thinner concrete sections than original design.
  • Do not increase mixing water when using fibres.
