TRUSTEK Copper/Brass Coated steel fiber is a special metal fiber with strong compression, tension and crack resistance. It is widely used in high-speed railway prefabricated parts, RPC cover panels, UHPC prefabricated parts and other important engineering components. It can greatly improve the strength, tensile strength, compression resistance, bending resistance, wear resistance, crack resistance, bending resistance, impact resistance, shear strength and impermeability of concrete, and increase the impact resistance and fatigue strength of concrete.
Main Features:
1. High strength, high safety& reliability.
2. High durability.
3. Light in weight.
4. Stable quality, easy modeling&beautiful appearance.
5. Long Service Life, Obvious time benefit.
6. Construction cost moderate, performance/cost ratio excellent.
Economic advantages:
1. Concrete consumption can be reduced by 30% ~ 50% under the same strength;
2. Rebar partially or completely no needed anymore, or reduce the diameter of steel bar for1~2mm;
3. Construction cycle shortened by 25%, suitable for projects where continuous and fast concrete placing is required;
4. Mixing as conventional concrete, no extra equipment needed.
Function:
The tensile strength and flexural strength of concrete can be increased by 20%-50% and 40%-80% when appropriate steel fiber is added to concrete. Under the usual fiber dosage, impact compression toughness can be increased by 2-7 times, impact shear, tensile toughness can be increased by several times to dozens of times. Because of the crack resistance and integrity of steel fiber concrete, the freeze-thaw resistance, heat resistance, wear resistance, cavitation resistance and corrosion resistance have been
significantly improved. Concrete collective itself is a kind of multi-phase, multi-component, non-uniform granular brittle composite material, its compressive ratio is only about one tenth, crack resistance is very low. The addition of steel fiber prevents the initiation of cracks and reduces the size and number of cracks. In the process of loading, the extension and expansion of cracks are inhibited, and the stress and concentration of cracks are alleviated.
Construction Proposals:
1. The amount of steel fiber is based on the design requirements of the engineering application design
institute. The general dosage is 90kg/m³-268kg/m³.
2. Steel fiber concrete mixing process: the construction shall be carried out according to the conventional construction without special adjustment.
