HPM® CR — Flake Wood Cellulose Fiber for Sustainable Concrete | PIONEER®
Natural Wood Cellulose Fiber for Crack Control, Cohesion & Eco-Friendly Concrete
PIONEER® HPM® CR is an advanced flake wood cellulose fiber engineered to improve crack resistance, cohesion, moisture retention, and long-term durability in concrete and mortar. Made from renewable cold-climate timber, this microfiber is designed for sustainable construction and high-performance cementitious systems.
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.

Key Benefits of Flake Wood Cellulose Fiber
Eco-Friendly Reinforcement
Made from renewable wood resources—ideal for green building and low-carbon projects.
Superior Secondary Dispersion
Flake structure enhances cohesion and mitigates fiber balling.
Plastic Shrinkage & Microcrack Control
Improves crack resistance during early hydration and curing.
Enhanced Durability
Increases freeze–thaw resistance and environmental stability.
Improved Workability & Stability
Reduces segregation and bleeding in fresh concrete.
Moisture Retention for Better Curing
Promotes dense, uniform, durable concrete.
Applications of HPM® CR Cellulose Fiber
Perfect for improving workability, crack resistance, and surface quality in:
-
Hydraulic structures: dams, canals, water channels
-
Infrastructure: bridges, tunnels, retaining walls
-
Decorative concrete: stamped surfaces, exposed aggregate
-
HPC/UHPC mixes requiring improved stability
-
Precast elements: blocks, pipes, façade panels
-
Mass concrete: foundations, industrial slabs
