Copper-Plated Steel Fiber for Concrete

Product introduction

RPC copper plated microfilament steel fiber is an important component of active powder concrete. RPC is a new material with ultra-high strength, high toughness, high durability, and good volume stability. RPC copper plated micro wire steel fibers are mainly used for high-speed railways, RPC, UHPC ultra high strength concrete, cover plates, and important engineering  prefabricated components. The fiber diameter is 0.2mm, the length is 13mm, and the tensile strength is >2850Mpa. It has properties such as high strength, tensile strength, wear resistance, crack resistance, bending resistance, flexural strength, and impact resistance.

Application area

1. RPC components: High-speed rail cover slabs and sleepers, enhancing strength, toughness, and durability.
2. UHPC projects: Bridge barriers and precast elements, improving tensile, flexural, and impact resistance.
3. High-strength concrete: Core columns and heavy-load beams, enhancing crack resistance and fatigue performance.
4. Ballistic-resistant structures: Protective works and shelters, improving penetration and blast resistance.

Construction suggestions

• RPC components: 2%–3% by volume, equivalent to 120–180 kg/m³.
• UHPC projects: 1.5%–2.5% by volume, equivalent to 90–150 kg/m³.
• High-strength concrete: 1%–2% by volume, equivalent to 60–120 kg/m³.
• Ballistic-resistant protective structures: 3%–5% by volume, equivalent to 180–300 kg/m³.
