When you choose FORTA-FERRO, you get the strength to do more than ever before.
FORTA-FERRO® is an easy-to-finish, color blended fiber, made of 100% virgin copolymer/polypropylene consisting of a twisted bundle non-fibrillating monofilament and a fibrillating network fiber, yielding a high-performance concrete reinforcement system. FORTA-FERRO is used to reduce plastic and hardened concrete shrinkage, improve impact strength, and increase fatigue resistance and concrete toughness. This extra heavy-duty fiber offers maximum long-term durability, structural enhancements, and effective secondary/temperature crack control by incorporating a truly unique synergistic fiber system of long length design. FORTA-FERRO is non-corrosive, non-magnetic, and 100% Alkali proof!
This patented fiber is actually a blend of two fibers:
- A standard fibrillated polypropylene fiber to reduce and control shrinkage and temperature cracking.
- A very heavy-duty twisted-bundle monofilament fiber made of a strong synthetic copolymer, to increase load-transfer and post-crack performance. This pre-blended fiber is typically used in long lengths (2-1/4″) and in high dosages (3.0 to 30 lbs. / cu. yd.) to affect a higher replacement level of reinforcing steel than standard synthetic fibers. FORTA-FERRO, which means “Strong as Steel”, is also extremely user-friendly, having gained a reputation as the best mixing and finishing fiber of its kind in the industry.
