Integrity UltraFibers

19mm AR Glass Fibers for GFRC

Each kilogram of Integrity UltraFibers has 65% more fibers than conventional thicker and heavier fibers. They also have higher than normal tensile strength.

This is because Integrity UltraFibers use smaller filaments

This balance of a lower filament diameter, greater number of fibers, and higher than normal tensile strength results in a premix fiber that exhibits higher performance at lower doses. CCI recommends a fiber dose of 2.5% for these fibers, rather than the 3% dose required for conventional fibers. Click here for how to calculate fiber dosage in GFRC mixes.

Another key benefit to lower tex fibers is reduced visibility in direct cast concrete surfaces.  UltraFiber's sizing is a unique formulation that ensures excellent strand integrity during mixing - the fibers won't shred. It also gives exceptional flow characteristics during casting - the fibers flow easily and smoothly.

Integrity chopped AR glass fibers are manufactured with a zirconia content in compliance with ASTM C1666/C 1666/M-07 and EN 15422 and under the recommendations of PCI and GRCA.
