TUF-STRAND SF is a patented polypropylene / polyethylene macro synthetic fibre successfully used to replace steel fibres, welded wire mesh and conventional reinforcing bars in a wide variety of applications.
TUF-STRAND SF fibres comply with ASTM C1116, Standard Specification for Fibre Reinforced Concrete and Shotcrete, and are specifically designed to provide equivalent tensile and bending resistance to conventional reinforcement requirements. Concrete reinforced with TUF-STRAND SF will have three-dimensional reinforcing with enhanced flexural toughness, impact and abrasion resistance and will also help mitigate the formation of plastic shrinkage cracking in concrete.
Dosage rates will vary depending upon the reinforcing requirements and can range from 1.8 kg/m³ to 12 kg/m³. TUF-STRAND SF synthetic macro-fibres comply with applicable portions of the International Code Council (ICC) Acceptance Criteria AC383 for synthetic fibres, are UL certified for composite metal deck construction and are recognised within ACI 360 and SDI/ANSI-C1.0 as an alternative reinforcement.
