Applicable standards and test methods
PIONEER® steel fibers are developed with reference to internationally recognized standards for steel fiber products and fiber-reinforced concrete. Applicable standards and documentation depend on the product grade, intended application, project requirements, and destination market.
-
ASTM A820/A820M — Standard Specification for Steel Fibers for Fiber-Reinforced Concrete
-
ASTM C1116/C1116M — Standard Specification for Fiber-Reinforced Concrete
-
EN 14889-1:2006 — Fibres for Concrete — Part 1: Steel Fibres — Definitions, Specifications and Conformity
These standards provide technical references for steel fiber selection and use in precast concrete, industrial floors, shotcrete, and other fiber-reinforced concrete applications. Product suitability should be confirmed according to the project design, required performance, and applicable local regulations.
Key Benefits of Using Micro Steel Fibre in UHPC
Using copper-coated micro steel fibre reinforcement in UHPC and high-performance concrete offers:
-
High Tensile Strength: >2,500 MPa for exceptional crack control and toughness.
-
Copper coating is part of the product specification. Any claimed effect on corrosion behavior should be supported by relevant product-specific testing.
-
Efficient Crack Control: Fine fibres distribute uniformly for effective bridging.
-
Lightweight and Efficient: Supports thinner, lighter concrete designs without compromising strength.
-
Enhanced Post-Crack Load Capacity: Improves structural integrity in UHPC and SFRC.
Improves crack control under dynamic loads
Enhances tensile strength, ductility in UHPC
Applications of Micro Steel Fibre in UHPC and Powder Concrete
Copper-coated micro steel fibres are widely used in:
-
High-Speed Rail Infrastructure: UHPC track slabs and joints for crack control and durability.
-
UHPC Bridges and Long-Span Structures: Enhanced flexural strength and impact resistance.
-
Tunnels and Underground Construction: Shotcrete and precast segments for ductility.
-
Powder Concrete Overlays: Ultra-thin overlays for structural repair and rehabilitation.
-
Precast UHPC Elements: Panels, façade components, and slim elements needing high strength.
-
Industrial Floors and Heavy-Use Pavements: Increased impact resistance under heavy loads.
-
Protective and Security Structures: Blast and impact resistance in UHPC barriers.
-
Bridge Decks and Overlays: Superior crack resistance and lifespan extension.
These fibres are ideal for SFRC, UHPC, powder concrete, and all advanced concrete systems where toughness and durability are critical.

How to Use Copper-Coated Micro Steel Fibre for Concrete
For optimal results with UHPC copper-coated micro steel fibre:
-
Dosage: 156–314 kg/m³, adjusted to design and project requirements.
-
Batching: Add fibres gradually during dry mixing for even distribution.
-
Mixing: Extend mixing time to prevent clumping.
-
Placement: Compatible with standard UHPC casting and finishing methods.
-
Finishing: Slight fibre visibility may occur but does not affect durability or performance.

FAQ
PNE® MS-6013 is a copper-coated micro steel fiber intended for UHPC, reactive powder concrete (RPC) and other compatible high-performance cementitious matrices.
Their small dimensions allow many individual fibers to be distributed within a fine cementitious matrix. When adequately dispersed and supported by mix testing, fibers crossing cracks can contribute to crack bridging and post-crack load transfer.
Copper coating is part of the product specification. Any claimed effect on corrosion behavior, mixing or matrix interaction should be supported by the current technical data and relevant testing.
Final dosage should follow the current product technical data sheet and approved UHPC or RPC mix design, taking into account fiber volume, workability, mixing sequence and required mechanical performance.
No. MS-6013 is a micro steel fiber intended for fine high-performance matrices; conventional macro steel fibers have different dimensions and are selected for different concrete systems and performance requirements.
