Copper Coated Micro Steel Fiber is an important component of reactive powder concrete, characterized by ultra-high strength, high toughness, exceptional durability, and good volume stability. It effectively reduces the self-weight of structures, significantly enhances their durability, and greatly diminishes the need for stirrups and tensile reinforcement, allowing for potential elimination of stirrups. It exhibits impact resistance, wear resistance, shear strength, tensile strength, crack resistance, dismantling resistance, bending strength, and high strength. It is primarily used in high-speed railways, exterior wall plastering, RPC slabs, and critical engineering components.
