PSI FIBERSTRAND 150

Synthetic Microfibers for Concrete

PSI FIBERSTRAND 150 is a monofilament polypropylene microfiber engineered to provide early-age crack control for concrete, mortar, and grout. Compliant with key industry standards, these synthetic microfibers for concrete effectively mitigate plastic shrinkage cracking, reduce segregation, and enhance surface durability. As a leading choice for fiber reinforced concrete in Africa, it delivers reliable performance across a wide range of applications.

Features & Benefits

• Plastic Shrinkage Crack Control: Actively controls and mitigates the formation of plastic shrinkage cracks in fresh concrete.
• Improved Concrete Integrity: Reduces segregation, plastic settlement, and bleed-water for a more uniform and stable concrete mix.
• Three-Dimensional Reinforcement: Provides multi-directional reinforcement against micro-cracking, improving overall toughness.
• Enhanced Durability: Increases surface durability while improving fire, impact, and abrasion resistance.
• Cost-Effective Alternative: Serves as a more efficient and lower in-place cost solution compared to traditional wire mesh for non-structural temperature and shrinkage crack control.
• Simple Integration: Easily added to the concrete mixture at any point before placement without requiring special equipment.

Applications

• Slabs-on-grade, sidewalks, driveways, and parking lots
• Footings, foundations, walls, and tanks
• Curb work, overlays, and toppings
• Stucco applications
• Precast and prestressed concrete elements
• Shotcrete and slope paving applications
• Composite steel deck construction
• Applications requiring spalling control and fire protection
