FORTA® ULTRA-NET® is an easy to finish, color blended, fully oriented, 100% virgin homopolymer polypropylene fibrous reinforcement in a unique twisted-bundle, collated fibrillated (network) form. FORTA® ULTRA-NET® is used to reduce plastic and hardened concrete shrinkage, improve impact strength, increase fatigue resistance and concrete toughness. This extra heavy-duty fiber offers ULTRA-NETWORKING power, maximum long-term durability, and true secondary/temperature control by incorporating a fibrillated pattern and long length option. Non-corrosive, non-magnetic and 100% Alkali Proof!
FORTA® ULTRA-NET® is mainly used with performance concrete applications such as slab-on-grade, shotcrete, tilt-up panels, architectural/colored concrete, precast – anywhere that optimum fiber performance is required, and where the objective is to control temperature/shrinkage/settlement cracking while improving long-term durability properties. Requires No Mix Design or Placement Changes!
Recommended dosage rate of FORTA® ULTRA-NET® is 1.6 lbs. per cubic yard (1.0 kg. per cubic meter) of concrete 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). Contact your local FORTA® representative for alternate dosage rates used in specialty applications.
