GREEN-NET®FAQ's

Frequently Asked Questions:


By itself Green-Net® does not significantly increase the value of recycled material used in a project. Green-Net® is typically added at a rate of 1.5 lbs/cu. yd. or 0.01% by volume. However, recycled fiber is another ingredient that can be combined with other "Green" ingredients, such as fly ash, reclaimed aggregates and recycled/storm water to calculate the amount of LEED points earned from the concrete.
Yes it does. ASTM C1116 states synthetic fibers should resist deterioration while in long-term exposure to the moisture and alkalies present in cement paste. Green-Net® is produced from recycled polypropylene, which is chemically inert and hydrophobic thus complying with the standard.
FORTA® products should be added to the concrete mixing system at the batch plant for best distribution. Follow the normal mixer manufacturers' standard recommendations and ASTM C-94. Mixing time should be a minimum of four to five minutes per load at a normal mixing speed. The batch plant will be the most economical and safest place for addition of the fibers. Typically it is not recommended that fibers be introduced to the mixer as a first ingredient, but added with other ingredients or at the end of the addition sequence. Contact FORTA® for mixing and addition recommendations for specific types of mixing equipment.
Green-Net® is made from post consumer polypropylene goods, which would normally be disposed of in area landfills. Instead these items are recycled and extruded into useable polypropylene fibrillated concrete fibers. Typical items collected for this process include but are not limited to the following polypropylene (PP) items: battery casings, netting, cargo bags, carpet face fibers, packaging film, label stock, strapping, drinking straws, and seed bags.
