Forta Ferro

PDFPrint
FORTA-FERRO® is an easy to finish, color blended fiber, made of 100% virgin copolymer/polypropylene consisting of a twisted bundle non-fibrillating mono- filament 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!

Description

 

FORTA-FERRO®

 

Guidelines

 

Recommended dosage rate for FORTA-FERRO® is 0.2% to 2.0% by volume of concrete (3 to 30 lbs. per cubic yard) added directly to the concrete mixing system during, or after, the batching of the other ingredients and mixed at the time and speed recommended by the mixer manufacturer (usually four to five minutes).

 

Applications

 

FORTA-FERRO® is mainly used with perfor- mance concrete specifications such as industrial floors, bridge decks, shotcrete, loading docks, and precast products – anywhere that steel reinforcement reduction or replacement is the objective. Contact FORTA Corporation or DE Fiberworks for design assistance.

 

Compliance

 

FORTA-FERRO® comply with the requirements of ASTM C 1116 “Standard Specification for Fiber-Reinforced Concrete and Shotcrete”.

 

Packaging

 

Convenient incremental pound or kilogram mixer-ready bag packaging.

FORTA-FERRO®

 

UL Classified: Type Forta Ferro fiber. For use as an alternate or in addition to the welded wire fabric used in Floor-Ceiling D700, D800, and D900 Series Designs. Fibers added to concrete mix at a rate up to maximum of 5.0 lb. of fiber for each cubic yard of concrete.

Reinforcement Objective

 

To inhibit plastic and settlement shrinkage cracking prior to the initial set, and to reduce hardened concrete shrinkage cracking, improve impact strength and enhance concrete toughness and durability as an alternate secondary/ temperature/structural reinforcement.

 

Mixing, Placing & Finishing

Mixing – FORTA-FERRO® fibers are packaged in pre-measured water soluble bags designed to be introduced into the concrete mix before, during, or after batching other concrete materials. Care should be taken to make sure the fibers are not added to the tail end of a high slump mix. Mixing should conform to ASTM C 94 with a minimum of 75 revolutions of the drum at full mixing speed to ensure uniform distribution of the fibers.

Placing – FORTA-FERRO® fibers can be pumped and placed using conventional equipment. Hand screeds can be used, but vibratory and laser screeds are recommended to minimize any surface fibers. At higher dosage rate of fibers, the use of a mid-range or high-range water reducer should be considered.

Finishing – Standard finishing equipment and techniques can be used when working with FORTA-FERRO® fibers. Finishing operations should begin as out- lined in ACI 302. Troweling blades should be kept flat for as long as possible to ensure a fiber free surface.

Did You Know?

Concrete is widely recognized as an extremely versatile, cost-effective construction material?

 

Concrete is widely recognized as an extremely versatile, cost-effective construction material. Yet it is also beset with some drawbacks that are inherent to its composition.  By generally accepted engineering standards, concrete is relatively brittle and lacks ductility.  Intertwined with these problems is concrete’s propensity to crack in both its plastic (early-age) and hardened (long-term) state.  Early-age cracks are microscopic fissures caused by the intrinsic stresses created when the concrete settles and shrinks over the first 24 hours after being placed.  Long-term cracking is in part caused by the drying shrinkage that transpires over time.  In either case, these cracks can jeopardize the overall integrity of the concrete and not allow it to maintain – or possibly ever attain – its maximum performance capability.

 

This is the basic reason reinforcement in concrete is required.  Irregular cracks are unsightly and difficult to maintain but generally do not affect the integrity of the concrete.  Joints in concrete slabs are simply pre-planned cracks that are created by forming, sawing, or tooling.  Concrete slabs that are designed for serviceability typically use reinforcement such as deformed reinforcing steel bars (rebar) or welded wire fabric (WWF) to hold cracks tight.  The primary function for the reinforcement is to maintain aggregate interlock for load transfer and improve joint stability.  Rebar and WWR do not inhibit the formation of cracks, but if properly positioned provide reinforcement once a crack has developed.  Fiber reinforcement can provide the same function, is distributed throughout the cross-section of the concrete and distributes the stresses attributed to shrinkage throughout the panel making the joints much more stable. This distribution of fibers provides a totally reinforced cross-section of concrete and changes the way the concrete works.
