FiberForce 150

General Information

FiberForce 150 is a monofilament microfiber manufactured from 100% virgin homopolymer polypropylene resins. FiberForce 150 fibers are used primarily as plastic shrinkage crack-control reinforcement in concrete. The finishability attributes associated with this technology (limited to no exposed surface fibers) make FiberForce 150 a great choice in residential applications.

Additional Information


Truck Mixed (Dry Batched) Concrete

  • Post-Loading (i.e. Tail Loading): FiberForce [100, 150, 300, 350, 500] fiber reinforcement is pre-packaged in degradable bags. The bags can be added after all the standard ingredients have been thoroughly mixed with the truck drum revolving at mixing speed. This typically occurs from the ready mixed concrete producers permanent scaffolding, a.k.a. “slump rack.” One common method for post-loading (tail loading) is for the driver to gather the required number of bags for the truck at the slump rack. Then back the concrete up to the point of discharge and add the bags of fibers to the mix. Once all fibers are added, start the drum and follow the mixing procedures outlined below. This helps to eliminate miscounting of the number of bags added to the truck.
  • Preloading: For truck-mixed concrete, the bags can be added into empty truck drums at the ready-mix plant followed by the coarse and fine aggregate, 1/3 to ½ of the mixing water, and then the remaining constituents so that the coarse aggregate can help break up the fiber. It is discouraged to add the fibers simultaneously with the cementitious constituents because the cement may coat the bags delaying their breakdown and delaying distribution of the fibers.

Central Mixed (Wet Batched) Concrete

  • Loading: It is typically recommended to post-load (tail load) the fibers after the concrete has been discharged into the truck because typical central mix plant configurations will limit the opportunity to add the fibers directly to the central mix drum. Please refer to dry batch concrete loading options above. If there is an opportunity to add fibers directly into the central mix drum, please consult with your FiberForce Technical Sales Manager for the best mixing procedures for your project.

Special Note: FiberForce offers the Acubatch Fiber Dispenser™ to dispense fibers accurately and seamlessly into both truck mixed and central mixed concrete. Click here for more information or contact your Technical Sales Manager.


When fibers are added directly to the truck (either preloading or post-loading), mix for 5 minutes at full charging speed (75-100 revolutions) to ensure complete, uniform fiber dispersion. Slower agitation speeds during transport to the site are insufficient for proper fiber dispersion and should not be counted toward the fiber mixing time.

If fibers are added to central-mix drum, please discuss the appropriate mixing cycle length with your FiberForce Technical Sales Manager.
