FiberForce 650

FiberForce 650TM (Tuf-Max DOTTM ) is a macrosynthetic fiber developed from a specific blend of polypropylene and polyethylene resins. FiberForce 650 was developed for use as temperature-shrinkage reinforcement and post-first crack toughness and will also provide plastic shrinkage reinforcement in concrete.

FiberForce 650 has been accepted by several State DOTs, Florida DOH, specifications, and code applications.

Applications

Interior
  • Commercial, Industrial, and Warehouse Slabs-on-Ground
Exterior
  • Slabs-on-Ground and Roadway and Highway Pavements
  • Shotcrete
  • Bridge Decks
Precast
  • Septic Tnanks
  • Burial Vaults
  • Utility Vaults

Recommendations for Use

Recommended dosage rate is typically, but not limited to, 3 – 11 lbs. per cubic yard. 

However, specific dosage rate should be established by the project engineer or government agency for a given application based on project conditions and requirements.

Mixing Instructions

FiberForce 650 is packaged in water-soluble bags that can be added directly into the concrete mix.

To ensure optimum distribution, the fibers must be introduced to the ready-mix drum during or after the concrete is batched and loaded into the truck.

A minimum of 75-100 revolutions at mixing speed or 5-7 minutes of mixing at high speed may be needed to ensure complete dispersion of the fibers.

Features & Benefits

  • Provides post- first crack residual strength to concrete
  • Provides temperature-shrinkage reinforcement
  • Increases concrete durability - including impact and abrasion resistance and fatigue strength
