Copper Coated Micro Steel Fiber for UHPC

Copper Coated Micro Steel Fiber for UHPC

Copper-coated steel fibers have a thin copper coating on the surface of the steel fibers. The diameter of the steel fibers is very small. The copper coating can enhance conductivity, corrosion resistance, and the adhesion to the substrate. The core difference between copper-coated steel fibers and other steel fibers lies in the performance upgrade brought by the surface copper coating. Their application scenarios are more focused on high-demand projects, especially suitable for scenarios that require durability and conductivity. Micro copper coated steel fiber is widely used in UHPC (Ultra-High Performance Concrete).

Copper-coated steel fibers feature:

◆ High intensity

Steel fibers are made of high-strength steel and can significantly improve the tensile, flexural and shear strength of concrete.

◆ High toughness

Steel fibers can absorb energy and improve the toughness of concrete, making it less vulnerable to brittle damage when subjected to impact or dynamic loads.

◆Enhanced Bonding: The copper coating improves adhesion to the matrix material.

◆Distribute evenly

The steel fiber can be evenly distributed in the concrete, forming a three-dimensional network structure, thus comprehensively enhancing the performance of the concrete.

◆ Excellent crack resistance

Steel fiber can effectively restrain the plastic shrinkage cracks and dry shrinkage cracks of concrete, and limit the expansion of cracks.

◆Good durability

Steel fiber can improve the fatigue resistance, wear resistance and impact resistance of concrete, and prolong the service life of the structure.

◆Copper-coated micro steel fiber has high resistance to flexural and shear

◆Convenient construction, strong adaptation

◆Fiber steel reinforced concrete has long life and cost-effective.

Comparison with ordinary uncoated steel fibers (high-carbon steel / low-carbon steel)

Corrosion resistance: The copper coating forms a physical barrier, providing stronger resistance to moisture and chemical corrosion, preventing rust from affecting the stability of the concrete structure.

Bonding strength: The copper layer has better adhesion to the concrete interface. When combined with the end-hook structure, the anchoring force is 20%-30% higher than that of ordinary steel fibers.

Service life: In humid and acidic/alkaline environments, the service life is extended by 3-5 times compared to ordinary steel fibers, reducing the maintenance cost in the long run.

The concrete function of copper-coated steel fiber in concrete：

◆Enhanced tensile and compressive properties

The high strength characteristics of coppered steel fiber make concrete better resistant to tensile and compressive deformation under external force, thus improving the mechanical properties of concrete.‌

◆Improve crack resistance

Copper-plated steel fiber like concrete put on a layer of protective clothing, effectively reduce the cracking of concrete, prolong its service life.‌

◆reduce structural dead weight

The use of copper-plated steel fiber can reduce the dead weight of concrete structure, making the structure more lightweight, suitable for long span or heavy load structure.‌

◆Improved durability

Copper-coated steel fibers can reduce micro-cracks in concrete, thereby increasing its durability.

Applications of copper-coated steel fibers:

◆High-end concrete projects: UHPC (Ultra-High Performance Concrete), RPC (Reactive Powder Concrete) products, such as bridge anti-collision guardrails and prefabricated components.

◆Special environment projects: Marine engineering, underground tunnels, sewage treatment plants and other humid/ corrosive environments, to prevent steel fibers from rusting and expanding, which could cause concrete cracking.

◆Functional scenarios: Industrial floors requiring anti-static and conductive properties (such as electronic factories, gas stations), the copper coating can enhance the conductivity of the concrete.

◆High durability requirements: Highway bridge decks, airport runways, heavy-duty workshop floors, to extend the service life of the structures and reduce maintenance frequency.
