Crack Control & Structural Reinforcement
Reduces Plastic shrinkage cracks by up to 70-90% (ASTM C157).
Controls macrocracks (width <0.1 mm) and macrocracks in hardened concrete.
Improved Durability
Freeze-thaw resistance:Increases cycles to failure by 30-50% (ASTM C666).
Abrasion resistance:Reduces surface wear by 20-40% (ASTM C944).
Enhanced Toughness
Impact resistance :Improves by 3-5x vs. plain concrete (ACI 544 testing).
Post-crack behavior:Maintains load-bearing capacity after cracking.
Workability & Homogeneity
Reduces bleeding/segregation by 40-60% , ensuring uniform mix consistency.
APPLICATION | DOSAGE (KG/M³) | KEY BENEFIT |
---|---|---|
Industrial Flooring | 0.6–1.2 | Anti-crack, high wear resistance |
Bridge Decks | 0.9–1.5 | Freeze-thaw protection, fatigue resistance |
Precast Concrete | 0.6–1.0 | Impact resistance, reduced handling damage |
Shotcrete (Tunnels) | 1.0–2.0 | Early-age crack control, cohesion |
Marine Structures | 1.0–1.8 | Chloride resistance, reduced spalling |
Vs. Steel Fibers : Lighter, no corrosion risk, and easier to mix.
Vs. PVA Fibers : Higher tensile strength and lower cost.
Ideal for : High-stress environments (warehouses, airports, dams) and decorative concrete (reduced surface defects).
