Carbon Fiber for Concrete
Ultra-High Strength Carbon Fibers for UHPC, Repairs & Structural Concrete
What Is HPM® Carbon Fiber?
HPM® Carbon is a premium chopped carbon fiber engineered for high-performance concrete, mortar, UHPC, and structural repair materials. With extremely high tensile strength, low density, and exceptional chemical durability, HPM® Carbon delivers major improvements in flexural capacity, impact resistance, crack control, and long-term structural performance.
As an advanced reinforcing additive, carbon fibers disperse uniformly throughout the cement matrix and provide micro-level reinforcement that steel mesh or bars cannot achieve—making them ideal for high-strength concrete, industrial repairs, overlays, marine structures, and precast UHPC elements.

How Chopped Carbon Fibers Strengthen Concrete
Chopped carbon fibers improve concrete performance by providing high-strength, high-modulus micro-reinforcement throughout the mix.
1. Early Crack Control
Carbon fibers bridge micro-cracks as soon as they form, reducing crack width and preventing crack propagation.
2. Higher Tensile & Flexural Strength
Their exceptional stiffness and tensile capacity enhance flexural strength, toughness, and post-crack performance—especially in UHPC and structural repair materials.
3. Improved Fatigue & Impact Resistance
Carbon fibers help concrete withstand repeated loading, vibration, and impact, making them ideal for industrial floors, bridge decks, and precast components.
4. Superior Durability
Because carbon fibers are corrosion-proof and chemically stable, they reduce pathways for water and chlorides, improving long-term durability in harsh environments.
5. Ideal for High-Performance Mix Designs
In dense UHPC matrices, carbon fibers contribute to high strength, ductility, and long-term dimension stability.

How to Use Carbon Fibers in Concrete
Follow these guidelines for best results when using chopped carbon fibers in UHPC and fiber-reinforced concrete:
-
Batching: Gradually add fibers during dry mixing to ensure even dispersion.
-
Dosage: 0.1–0.3% by volume, equivalent to 2–6 kg/m³ depending on performance requirements.
-
Mixing: Utilize high-shear mixing where possible; extend mixing time to prevent agglomeration.
-
Placement: Use standard UHPC and FRC placement and vibration methods to ensure full compaction.

FAQ
HPM® Carbon is a chopped monofilament carbon fiber designed for incorporation into concrete, mortar and other cementitious materials. It is different from continuous CFRP wraps, laminates, bars or mesh systems.
When adequately dispersed, short carbon fibers can provide distributed reinforcement and participate in localized crack bridging. The resulting flexural, toughness or post-crack performance depends on fiber grade, dosage, matrix properties and applicable testing.
Final dosage should follow the current HPM® Carbon Technical Data Sheet and should be selected according to fiber grade, matrix type, mixing capability and required performance.
No. HPM® Carbon is a chopped distributed fiber product and should not be treated as a universal replacement for rebar, CFRP wraps, carbon bars or other primary structural reinforcement.
