🧱 What is Anti-Crack Fiber?
Anti-crack fiber is a short-cut fiber material that can be evenly distributed in mortar, concrete, or gypsum.
Its main function is to prevent cracks caused by shrinkage, temperature changes, or stress,
greatly improving the crack resistance, toughness, and durability of the mix.
🔍 How It Works
During the setting and drying process, millions of fibers form a 3D reinforcing network inside the mix.
When microcracks appear, the fibers bridge across the cracks, absorb stress, and stop further propagation,
keeping the mortar stable and intact.
💪 Key Benefits
Excellent crack control: Prevents both plastic shrinkage and drying cracks
Improved toughness: Fibers enhance tensile and flexural strength
Better waterproofing: Reduces crack channels and enhances impermeability
Higher impact and abrasion resistance: Increases surface strength and service life
💡 Application Tips
- Mix fibers evenly with dry materials before adding water.
- Recommended dosage:
0.9–1.2 kg/m³ (adjust according to mortar type).
- Suitable for plastering mortar, tile adhesive, repair mortar, self-leveling compounds, and concrete systems.
