Micro-Synthetic Fiber, Fibrillated

PSI FIBERSTRAND F is a fibrillated polypropylene micro-fiber for concrete reinforcement that complies with ASTM C 1116, Standard Specification for Fiber Reinforced Concrete and Shotcrete, and is specifically designed to help mitigate the formation of plastic shrinkage cracking in concrete. Typically used at a dosage rate of 1.5 lbs/yd³ (0.9 kg/m³), PSI FIBERSTRAND F micro-fibers have been shown to greatly reduce plastic shrinkage cracking when compared to plain concrete. PSI FIBERSTRAND F micro-fibers also comply with applicable portions of the International Code Council (ICC) Acceptance Criteria AC32 for synthetic fibers

Features & Benefits

  • Controls and mitigates plastic shrinkage cracking
  • Reduces segregation, plastic settlement and bleed-water
  • Provides three-dimensional reinforcement against micro-cracking
  • Increases surface durability, impact and abrasion resistance
  • Reduction of in-place cost versus wire mesh for non-structural temperature / shrinkage crack control
  • Easily added to concrete mixture at any time prior to placement

Applications

  • Slabs on grade, sidewalks, driveways, curb work, overlays and toppings
  • Footings, foundations, walls and tank applications
  • Stucco applications, pre-cast concrete and pre-stressed beams
  • Shotcrete, slope paving and composite steel deck construction

Specifications / Compliances

  • ASTM C1116
  • ASTM D7508

Packaging

PSI FIBERSTRAND F micro-fibers are packaged in 0.75 lb (0.34 kg), 1.0 lb (0.45 kg) and 1.5 lb (0.68 kg) water soluble bags. Special packaging configurations are also available upon request.
