Overview

FORTA® FERRO-GREEN® is a unique blend of recycled polypropylene and copolymer macro fibers designed specifically for pervious concrete applications. The FERRO-GREEN® blend consists of 100% recycled polypropylene fibrillated (network) fibers and a high-performance twisted-bundle macro-monofilament fiber, designed to mix, distribute, and finish well in pervious concrete mixes. 

This fiber combination offers a variety of desirable benefits to pervious concrete pavement applications, including increased strength, toughness, freeze-thaw resistance, and durability.

Applications

FERRO-GREEN® is used to toughen any pervious concrete application, such as driveways, curbs and sidewalks, and commercial parking lots and pavements. The three-dimensionally distributed non-corrosive macro fiber blend is one of the few methods available to add true toughness reinforcement to pervious cross-sections, without reducing porosity.

FERRO-GREEN® also increases resistance to freeze-thaw damage and raveling, while preserving both the plastic and hardened concrete void structure.

Installation

FERRO-GREEN® is generally dosed in a range of 0.17% to 0.5% by volume of concrete, or 2.5 lb. to 7.5 lb. per cubic yard of pervious concrete, depending on the desired level of additional toughness and crack-control required for the application.

FERRO-GREEN® - Pervious
Fiber Length: 2.25" | Dosage: 4.0lbs./cu. yd.

FORTA-GREEN® was used in a pervious concrete application due to address the runoff issues for their parking lot.

FERRO-GREEN® - Parking Lot, Pervious
Fiber Length: 2.25" | Dosage: 5.0lbs./cu. yd.

The project involved over 100,000 sq. ft. of parking spaces and driving lanes placed over 10 inches of water-retention and recharge bed material.

FERRO-GREEN® - Slab-On-Metal-Deck
Fiber Length: 2.25" | Dosage: 4.0lbs./cu. yd.

FORTA-FERRO® was used to reinforce a slab-on-metal-deck project for a skilled nursing facility in Erie, PA due to its ability to provide strength & savings.

FORTA-FERRO® was used to replace steel reinforcement, to eliminate safety concerns & corrosion, for a large slab-on-ground.
What are the cost comparisons between FORTA-FERRO® and steel reinforcement? 2016-12-28T09:16:15+00:00

There are many factors to take into consideration. Steel fibers typically require special conveyors or extra man-hours to add them due to the high dosage per cubic yard. Steel mats or rebar are very labor intensive to place on chairs and supports and to tie properly. The 3-dimensional FORTA-FERRO® fibers can be placed with a laser guided screed and can eliminate the need for a concrete pump in these situations. The FORTA-FERRO® benefits can reduce labor hours and placement time, providing significant job savings.

How does FORTA-FERRO® affect placement and finishing? 2016-12-28T09:16:45+00:00

FORTA-FERRO® fibers are added at the concrete batch plant and require 4-5 minutes at normal mixing speed for proper distribution. They will reduce visual slump approximately 3″ at the 7.5 lb. dosage, and will typically require a super-plasticizer or mid-range water reducer to provide flowability for placement. Using excessive mix water will naturally reduce concrete strength and create bleed water that will make the surface less durable. Good concrete finishing practices should be exercised.

Can FORTA-FERRO® replace wire mesh, steel mats or rebar in slab-on-grade concrete? 2016-12-28T09:15:23+00:00

In most situations, FORTA-FERRO® can safely and reliably replace all non-structural steel in slab-on-grade concrete. Factors such as requirements from rack or point load, average daily traffic, slab thickness and sub-base must be considered. As always, it is best to contact the FORTA® Engineering Department before eliminating steel reinforcement.

What benefits do FORTA-FERRO® fibers have over steel fibers? 2017-03-21T15:05:03+00:00

FORTA-FERRO® (which means “Strong as Steel”) fibers are non-corrosive, non-magnetic and 100% alkali proof. In comparison testing vs. three types of steel fibers it was determined that it requires 1 pound of FORTA-FERRO® fiber to offer equivalent A.R.S. (Average Residual Strength) values to that of 10 pounds of steel fibers. This one-to-ten dosage ratio offers tremendous advantages for FORTA-FERRO® fibers in the batching, pumping, placing and finishing processes.
