Wood Cellulose Fiber for Concrete
Natural Wood Cellulose Fiber for Crack Control, Cohesion & Eco-Friendly Concrete
What Is PIONEER® HPM® CR Flake Wood Cellulose Fiber?
PIONEER® HPM® CR is a refined flake wood cellulose microfiber (buckeye fiber) used to enhance concrete cohesion, reduce cracking, and improve surface quality.
Its unique flake structure promotes secondary dispersion during mixing, ensuring uniform fiber distribution in cementitious systems. This leads to improved workability, reduced bleeding, and superior resistance to microcracking—while supporting low-carbon construction practices.

Looking for Cost-Effective High-Performance Concrete Reinforcement?
High-performance fibers such as PVA fiber, basalt fiber, carbon fiber, and aramid fiber are widely used in high-performance concrete (HPC) and UHPC.
They deliver excellent strength and toughness—but in real projects, their high cost limits large-scale application, making them suitable mainly for specialized or high-end use.
A More Practical High-Performance Fiber
Rimix™ NanoRebar is designed to bring high-performance concrete reinforcement into everyday projects.
It provides:
-
High tensile strength and modulus for effective crack control
-
Performance in both plastic and hardened stages
-
Improved toughness and long-term durability
-
Ultra-fine fibers for better dispersion and efficiency
With lower dosage and optimized cost, NanoRebar makes high-performance concrete more practical and scalable.

FAQ
HPM® CR is a flake wood cellulose fiber designed for concrete, mortar and other cementitious materials. It can be evaluated where fresh-state cohesion, fiber distribution and early-age microcrack control are important product-selection criteria.
Wood cellulose fiber can be evaluated for fresh-state cohesion, bleeding or segregation control, surface behavior and early-age crack-control functions in compatible cementitious mixes. Actual performance depends on product dosage, matrix and mixing conditions.
HPM® CR is described as a wood-derived cellulose fiber rather than a polypropylene-, PVA- or PAN-type synthetic polymer fiber. Final material classification should follow the current HPM® CR technical documentation.
Final dosage should follow the current HPM® CR Technical Data Sheet and should be selected according to matrix type, required fresh-state behavior and crack-control objective.
Yes, HPM® CR can be evaluated for compatible mortar, repair and overlay systems where fiber distribution, cohesion and early-age crack-control requirements support its use. Mix trials are recommended for new formulations.
