DAYE cold drawn low carbon steel wire fiber is a special kind of metal fiber, in the concrete compressive strength, tensile strength, bending strength, impact strength, toughness, impact toughness and other properties have been trap improved. It is widely used in highway pavement, airport pavement, bridge pavement, bridge expansion joint, water conservancy and hydropower and other heavy large-scale infrastructure projects.
Characteristics:
1. Has high strength, high safety and reliability.
2. High durability.
3. Having the character of lightweight.
4. Stable quality, easy to shape and beautiful appearance.
5. Long service life and obvious long-term benefit.
6. The engineering cost is moderate and the performance/price ratio is excellent.
Economic advantages:
1.The amount of concrete can be reduced by 30%~50% under the same strength.
2.Can replace or partially replace the steel bar or reduce the diameter of steel bar 1~2 mm;
3.Can shorten the construction period of more than 25%, especially suitable for continuous, rapid pouring of concrete engineering;
4. The same mixing construction with ordinary concrete requires no additional equipment.
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:
1. The quantity of steel fiber is according to the design requirements of the actual engineering application design Institute.The general dosage is 30 kg/m3-80 kg/m3.
2. Steel fiber concrete mixing process: the construction according to the conventional construction, no special adjustment.
Application:
1. Hydraulic dam
2. Port and ocean engineering
3. Tunnel and mine engineering
4. Pipeline engineering
5. Other construction projects
