How does MasterFiber F 70 work?

MasterFiber F 70 product, a synthetic microfiber, is a fibrillated polypropylene fiber manufactured from 100% virgin homopolymer polypropylene resins. MasterFiber F 70 product provides shrinkage and temperature (secondary) reinforcement in concrete applications.

Recommended uses:

  • Residential and commercial slabs-on ground
  • Ultra-thin whitetopping
  • Bonded overlays
  • Architectural precast products and ornamental elements
  • Slope stabilization
  • Water treatment plants
  • Irrigation ditches/channels

What are the unique features of MasterFiber F 70?

  • Excellent distribution throughout concrete
  • Excellent shrinkage and temperature reinforcement
  • Meets the requirements of ASTM C 1116/C 1116M, Section 4.1.3, Type III, and Note 2
  • Meets the requirements of ICC ES AC32 Sections 3.1.1 (plastic shrinkage reinforcement) and 3.1.2 (shrinkage and temperature reinforcement)

How does MasterFiber F 70 benefit contractors?

  • Replacement for typical light gauge welded-wire reinforcement [(6 x 6 W1.4 x W1.4) (152 x 152 MW9.1 x MW9.1)], depending on the application
  • Modifies macro-cracking and micro-cracking mechanisms
  • Reduces plastic settlement
  • Extends service life with reduced maintenance
  • Enhances fatigue strength
  • Enhances impact, pullout and surface abrasion resistance
  • Reduces permeability
