Crimped steel fiber is belong to high performance steel fiber can improve concrete's anti impact and anti fatigue ability improve the concrete impermeability, because of its high tensile strength, good toughness, low price and other characteristics, so often used is arranged into rows of steel fiber alternatives. Compared with other shapes of steel slope, bridges, tunnels, airports, ports, rail pillow are widely used.
Application
1,the highway bridge: highway pavement, bridge deck pavement, box arch bridge, continuous box girder;
2,dam, underground powerhouse, hydraulic tunnel lining, water erosion wear parts, gate, gate slot, aqueducts
3,the railway engineering prestressed concrete railway sleeper, double block type railway sleeper;
4,harbor and ocean engineering: steel pipe pile anti corrosion, wharf facilities, submarine concrete facilitie;
5,tunnel and underground engineering: hydraulic tunnel lining, mine tunnel, railway, highway tunnel lining;
6,pipeline engineering: centrifugal tube, vibration and extrusion pipe, pump tube, steel fiber concrete pressure pipe.
Technology advantage
1.improve the bonding properties of the steel fiber reinforced matrix, that is,
to improve the concrete matrix, such as the use of higher strength concrete
2.increasing the bond length of the fiber, that is, increasing the length to diameter ratio, the formula of lf/df.
3.improve the shape of the fiber, increase the friction and bite force between the fiber and the matrix, that is, to improve the influence coefficient of steel fiber.
The compressive strength, tensile strength, bending strength, impact strength, toughness and impact toughness of steel fiber reinforced concrete are greatly improved.
