FiberForce 850

FiberForce 850TM (formally, Advanced Performance BlendTM ) is a blend of FiberForce T5-50TM and FiberForce 150TM. FiberForce 850 fibers are primarily used as plastic shrinkage crack reinforcement and post-first crack toughness in concrete.

Applications

Interior
  • Commercial
  • Light, Medium, and Heavy Industrial and Warehouse Sites
Exterior
  • Ingress-egress roadways and industrial and warehouse sites
  • Parking facilities and malls
  • Bonded concrete overlays
Precast
  • Septic tanks
  • Vaults
Elevated decks with composite steel decking
Shotcrete

Recommendations for Use

Recommended dosage rate is typically between, but not limited to, 24 – 48 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.

Please note that at 23 lbs. per cubic yard of FiberForce T5-50, the steel fibers function purely as a secondary reinforcement.

* Blend of 23 lbs. per cubic yard of FiberForce T5-50 and 1 lb. per cubic yard of FiberForce 150.

Mixing Instructions

FiberForce 850 fibers are pre-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.

For detailed mixing, placing and finishing instructions, please contact your Regional FiberForce Expert.

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
  • Reduces plastic shrinkage and settlement cracking
  • Reduces water migration, bleed water, and permeability of concrete
  • Provides uniformly distributed reinforcement throughout the concrete, not just in one plane as with traditional steel reinforcement
  • A cost-effective alternative to traditional steel reinforcement
