Reinforcing Fiber

Reinforcing Fiber

Understanding fiber differences allows you, the concrete user, to best determine the right fiber to attain your desired results.

Level 1: Econo-Mono®

Very fine monofilament fibers are generally used at a low dosage such as 1.0 lb. per cubic yard of concrete to reduce plastic shrinkage cracking prior to initial set. Made in short lengths of polypropylene they are easy to add and mix, and result in a near invisible surface finish.

  • Reduce plastic shrinkage cracking
  • Used in conjunction with steel
  • Fine monofilament fiber
  • 1.0 lb./cubic yard
  • 1/2” – 3/4” length
Level 2: Econo-Net®

Fibrillated, or net-shaped fibers are generally used in concentrations of 1.5 to 3.0 lbs./cubic yard to reduce plastic and hardened concrete shrinkage cracking, and act as a viable alternative to wire mesh, in many applications. Made of polypropylene in short to medium lengths.

  • Reduce plastic shrinkage and temperature-related cracking
  • Some light steel replacement
  • Fibrillated-net fiber
  • 1.5 to 3.0lb./cubic yard
  • 3/4 – 1-1/2” length

FORTA-FERRO® has the highest slab curling reduction and best post-crack performance values of any synthetic fiber in its class.

Level 3: Forta Ferro®

Heavy-duty macro-synthetic fibers represent the next generation of synthetic technology, capable of a much more higher replacement level than conventional steel reinforcement. The FORTA-FERRO® macro fiber maximizes each of the critical fiber characteristics that contribute to long term durability and crack-control performance. Using advanced co-polymer chemistry and a blend of fiber shapes, along with twisted bundles and special gray color to assure uniform mixing and excellent surface finish, this unique best-of-its-kind macrosynthetic may be used at a much higher dosage (3.0,5.0,7.5 lbs./cu.yd. or more). FORTA-FERRO® has the highest slab curling reduction and best post-crack performance values of any synthetic fiber in its class.

  • Reduce plastic and hardened concrete shrinkage, and temperature-related cracking
  • Add toughness and increased post-crack behavior
  • Higher level of steel replacement
  • Heavy-duty macrofilament and fibrillated blend
  • 3.0,5.0,7.5 lbs./cubic yard and higher
  • 1-1/2” – 2-1/4” length
  • 1-1/2” – 2-1/4” length
  • 1-1/2” – 2-1/4” length
  • 1-1/2” – 2-1/4” length
