FibroMac™ Synthetic Fibers

FibroMac™ Synthetic Fibers are multi-filamentary fibers obtained from virgin polypropylene. These fibers are made to be included in the cement matrix (concrete, grout, etc.) in order to constitute a homogeneous material able to inhibit plastic shrinkage cracking.

Maccaferri’s FibroMac™ synthetic fibers can be mixed and homogeneously dispersed through the concrete to control its plastic shrinkage and, consequently, increase compactness and oppose micro-cracking.

FibroMac™ synthetic fibers come in a convenient hydro soluble package sized to most commonly used dosage rates.

Maccaferri recommends a blend of Wirand® steel fibers and FibroMac™ synthetic fibers to complement all the concrete effects from shrinkage to the structural long term behavior.

Applications include:

  • Residence floorings
  • Industrial floorings
  • Parking lots
  • Airport pavements
  • Curtain walls
  • Precast concrete elements
  • Shotcrete
  • High performance concrete mix
