Confiber is a polypropylene fiber specifically designed for the reinforcement of cementitious mortars and concrete mixes and can be easily incorporated in the concrete mix.

It is a widely accepted fact that traditional concrete mixes are prone to plastic shrinkage during the setting phase and this can lead to cracking. ConTech Chemicals developed CONFIBER specifically for the reinforcement of cementitious mortars and concrete mixes. These fibers are made of Alkali Resistant Polypropylene and resistant to acids, other chemicals and can be easily incorporated in the concrete mix. Having the fibrillated structure it ensures better binding and anchoring of aggregates in concrete and plaster Mortar.

  • Ideal aspect ratio ( ratio of length to diameter )
  • Highly resistant to adds, alkalis and other chemicals
  • Non rotting, non-corroding composition
  • Safety in use, no health risk.
  • Replaces non structural; steel in roads and chicken mesh in plastering of buildings and there by reduces the high cost.
  • Enhanced mechanical properties, not only in the plastic stage but also in the hardened stage.
  • Save Cement Consumption in plastering madam.
  • Easy incorporation into concrete
  • Reduces permeability and therefore increases durability.
  • Inhibits plastic shrinkage cracks and settlement cracks by more than 85%.
  • Confiber does not allow moisture or water to seep in due to reduction in permeability.
  • Distribute localized stresses and increase fatigue resistance.
  • Reduces unequal bleeding so solids in concrete do not settle unevenly and enhances cement hydration in fresh concrete thereby increasing tensile compressive and flexural strength.
  • Improves fire resistance characteristics in concrete and mortars as well reduces risk of spelling in concrete structures.
  • Increase impact strength sand abrasion resistance.
  • Reduces rebound losses.
  • Reduces breakages during production and transportation of precast concrete units.

Procedure For Mixing:
Mixer Machine:
  • Add Confiber in the mixture containing concrete and mortar aggregate with water at the specify dosage mentioned above. Mix thoroughly for 3 to 4 minutes.

Manual Mixture:
  • Spread Confiber on the heap of dry concrete / mortar evenly and mix the Confiber for two to three times. Add water to the dry mix and that wet mix thoroughly for 2 to 3 minutes.

Recommended Size Of Confiber In Different Application:
Size Application
  • 6 mm : Internal / External plaster / Cracks / construction joints
  • 12mm : Tennis Court Repair, Restoration of canal /mine/tunnel lining / bridgeDeck / Guniting
