Synthetic Microfiber, Fibrillated
PSI FIBERSTRAND F is a fibrillated polypropylene microfiber 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 microfibers have been shown to greatly reduce plastic shrinkage cracking when compared to plain concrete. PSI FIBERSTRAND F microfibers 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) and 2.0 lb (0.9 kg) water soluble bags. Special packaging configurations are also available upon request.
