TUF-STRAND SF

TUF-STRAND SF is a patented polypropylene / polyethylene macro synthetic fiber that has been successfully used as a replacement for steel fibers, mesh steels and conventional reinforcing bars in a wide variety of applications. TUF-STRAND SF fibers comply with ASTM C1116, the standard specification for fiber-reinforced concrete and shotcrete, and are specifically designed to provide tensile and bending strength equivalent to conventional reinforcement requirements. TUF-STRAND SF reinforced concrete will provide three-dimensional reinforcement with increased flexural strength, impact and abrasion resistance, and will also help reduce the formation of plastic shrinkage cracks in concrete. Dose rates will vary depending on supplementation requirements and may range from 1.8 kg/m3 to 12 kg/m3. TUF-STRAND SF macro-synthetic fibers comply with the relevant parts of the International Code of Conduct (ICC) AC32 Acceptance Criteria for synthetic fibers, are UL approved for composite metal deck construction and are considered alternative reinforcements under ACI 360 and SDI/ANSI-C1.0. .

PRIMARY APPLICATIONS

• Slab on Grade and elevated construction (distribution centers, warehouses, etc.)
• Thin walled pre-cast (septic tanks, vaults, walls, etc.)
• Shotcrete for tunnel linings, pool construction and slope stabilization
• Pavements and white-toppings

FEATURES/BENEFITS

• Equivalent strengths to WWM and rebar provided by engineering calculations 
• Controls and mitigates plastic shrinkage cracking and reduces segregation and bleed-water 
• Provides three-dimensional reinforcement against micro and macro-cracking
• Reduces equipment wear, fiber rebound and increases build-up thickness compared to steel fibers for shotcrete applications
• Increases overall concrete durability, fatigue resistance and flexural toughness
• Reduction of in-place cost versus wire mesh • Easily added to concrete mixture at any time prior to placement
• Applicable for design by ACI 332, ACI 360 and ACI 544 • Tested in accordance with ASTM C1609, ASTM C1550 and EN 14651
• Certified for use by UL/ULC for D900 and F900 Series metal deck assemblies as alternate to WWM (CBXQ.R13773)
• Reduction of carbon footprint (CO2eq) compared to conventional reinforcement
