What Makes Flake Wood Cellulose Unique?

PIONEER® flake wood cellulose fibers are monofilament fibers with a diameter of 0.03 mm and length of 6 mm. Their flake-shaped structure provides an extensive surface area that promotes excellent adhesion with cement paste, surpassing many synthetic fibers in performance.

Key physical properties include:• Tensile strength: 500–900 MPa• Modulus of elasticity: 7–10 GPa• High resistance to alkali, acid, and salt environments• Sustainable and biodegradable material

How Flake Wood Cellulose Improves Concrete Durability

These natural fibers enhance concrete by:• Creating a tight reinforcing network that bridges microcracks• Improving flexural strength and toughness• Increasing resistance to shrinkage and drying cracks• Maintaining volume stability under environmental stresses

Applications Where Durability Matters Most

Flake wood cellulose fibers are especially effective in:• Industrial floors and precast elements• Decorative concrete and architectural panels• White cement concrete mixes• Repair mortars and shotcrete applications

Their eco-friendly profile makes them a preferred choice for sustainable construction projects demanding both performance and environmental responsibility.

Conclusion: Natural Science Driving Concrete Longevity

The science behind flake wood cellulose demonstrates how natural fibers can outperform traditional additives in reinforcing concrete durability. By integrating these fibers, concrete becomes stronger, more crack-resistant, and better suited for long-term structural integrity.
