Rockbond Polypropylene Fibres (PPF) test


ROCKBOND POLYPROPYLENE FIBRES 6mm (RB PPF6) are strong, inert, monofilament polymer fibres specially designed to improve the plastic and hardened properties of cementitious materials.  Mortars, renders and concretes are more workable and cohesive when plastic, and flowing materials harden to produce products with greater flexural and tensile strengths. The fibres are also used to reduce or eliminate problems associated with drying out, shrinkage and cracking.  The fibres are supplied in 1kg water dispersible packs, and have an indefinite shelf life.


  • 1g of ROCKBOND POLYPROPYLENE FIBRE 6mm produces 30,000 individual fibres!
  • Quickly and easily mixed with cement and dispersed without bundling throughout the mix.
  • RB PPF6 modified mixes are plasticized and cohesive, have a low bleed and a low air content.
  • The enhanced workability, stability and pumpability of RB PPF6 mixes facilitate application.
  • The fibres are non absorbent, chemically resistant and will not degrade with time.
  • Fibres develop a strong adhesive and mechanical bond to cement.
  • Minimises shrinkage, reduces or eliminates both plastic and long term shrinkage.
  • Reduces or eliminates cracking to produce impermeable and durable products.
  • Cured materials are strong in flexion and tension.
  • Produces surfaces that are quickly finished, strong and resistant to impact and abrasion.
  • High yielding, economical, non flammable, non toxic, odour free, user friendly and safe to use.


  • For use in mortars, renders and plasters to aid placing, working and finishing.
  • To reduce plastic settlement and shrinkage in mass concrete and concrete floors.
  • To produce low rebound, sprayed concrete mixes that are cohesive and high build.
  • To increase the flexural and tensile strength of site batched and precast mortars and concrete.
  • To eliminate cracking and crazing in cementitious screeds, thin toppings and coatings.
  • In roads and car parks which are exposed to frequent and heavy vehicular movement.
  • For precast concrete units, manhole rings and covers, frames, posts, kerbs, tiles and slabs.
