What is the mechanism?

FORTA is a color blended macrosynthetic fiber consisting

  • f a twisted bundle non-fibrillating monofilament and a

fibrillating network fiber, yielding a high-performance concrete reinforcement system. This extra heavy-duty macrosynthetic 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.

Installation

Recommended dosage rate of FORTA fiber is 1 - 4.5 Kg/m3 added directly to the concrete mixing system during, or after, the batching of the other ingredients and mixed for usually 4-5 minutes. FORTA fibers can be added to concrete truck mixer on site, too.

Feasibility Study

So by using FORTA FERRO Fibers we can achieve to at least

1.0 $/m2 Saving in construction costs.

Beside economical advantages FORTA provides: Reduced labor Reduction of Cracking Enhancements to ductility, toughness and impact resistance Elimination of the potential for reinforcement corrosion

5- Three Dimensional Performance

When a crack occurs, the traditional rebars can not meet the shrinkage stresses occurred on the structural bearing points. FORTA provides the resistance with 3 dimension and increases the bending resistance on every part of the structure.

6- Freezing and Thawing Resistance

FORTA provides freezing and thawing resistance by stopping cracks to continue, holding the concrete together, preventing the impairment of the aggregate-cement matrix, holding the breakage

7- Elastic Behavior

The changes of the concrete is much limited since the concrete has a brittle behavior. The possibility of failure comes out even

  • n the values under carrying capacity in consequence of the

fatigue effect under the repeated loadings.

Test Results

FORTA vs. Steel Fibers

  • In addition to concerns regarding corrosion and

rising costs, steel fibers can be challenging to add, mix, and shoot at the elevated dosages (50 to 120 lbs./cu. yd.).

  • Ready-mix concrete producers often encounter

difficulties in adding steel fibers in an even manner that will facilitate uniform distribution and minimize clumping and balling.

  • Steel fibers typically have little if any affect on the

reduction of plastic shrinkage cracking, an area where FORTA synthetic fibers shine.

FORTA has shown dramatic improvement to impact resistance as tested by the ACI Committee 544 Drop Hammer test. Most impressive is the fiber’s ability to allow for specimen integrity, even after first crack.
