The functional and effective characteristics of copper plated micro wire flat steel fibers. The mixture of copper plated micro wire steel fibers is made of cement, water, coarse and fine aggregates, steel fibers, and necessary chemical additives or admixtures added in a certain proportion. The correct selection of the composition data of the mixture has an important impact on the physical and mechanical functions and construction of steel fiber reinforced concrete. The bond strength between steel fibers and cement mortar can be determined by direct drawing method according to the "Standard Test Methods for Steel Fiber Reinforced Concrete" (CECS89). Due to the fact that the damage of steel fiber reinforced concrete is primarily caused by the extraction of steel fibers rather than their breakage, the reinforcement of steel fibers primarily depends on the bonding strength of the steel fiber reinforced concrete matrix interface. Fiber reinforced concrete is a general term for composite materials composed of fibers and cement-based materials (cement stone, mortar, or concrete). The main disadvantages of cement stone, mortar, and concrete are low tensile strength, low ultimate elongation, and brittleness.
Copper plated micro wire steel fiber is a type of metal fiber with strong compressive, tensile, and crack resistance properties. It is widely used in high-speed rail prefabricated parts, RPC cover plates, exterior wall painting, and important engineering components. It can greatly improve the tensile, compressive, shear strength, impermeability, impact resistance, and fatigue strength of concrete. Adding an appropriate amount of steel fibers to concrete can increase its tensile strength by 20% -50% and flexural strength by 40% -80%. Under the usual fiber content, the impact compressive toughness can be increased by 2-7 times, and the impact shear and tensile toughness can be increased by several times to tens of times. Due to its good crack resistance and overall integrity, steel fiber reinforced concrete has significantly improved resistance to freeze-thaw, heat, wear, cavitation, and corrosion. The concrete collective itself is a multi-phase, multi-component, non-uniform granular brittle composite material, with a compression ratio of only about one tenth and low crack resistance. The addition of steel fibers prevents the initiation of cracks and reduces the scale and quantity of crack sources; During the stress process, the extension and expansion of cracks are suppressed, and high-quality copper plated micro wire steel fibers are used for high-strength concrete steel fibers.
