Flake Wood Cellulose Fiber for Sustainable Concrete | PIONEER®
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.
