Steel Fiber for high Strength Reinforcement concrete

Steel Fiber for high Strength Reinforcement concrete

Steel fiber refers to the aspect ratio (the ratio of fiber length to diameter) made by cutting thin steel wire, cold-rolled strip shearing, steel ingot milling or rapid condensation of molten steel. When the fiber section is non-circular, the equivalent section circle is converted The diameter of the area) is 40 to 80 fibers.

Steel Fiber Reinforcement

Steel fiber is to cut fine steel wire method, cold-rolled strip shear, ingot milling or steel fast condensation method to make the length to diameter ratio (the ratio of fiber length to its diameter, when the fiber cross-section is non-circular, using the diameter of the equivalent cross-sectional area) for 40 ~ 80 fiber. Steel fiber is one of the new composite building materials developed rapidly in recent years, can make the concrete tensile strength, bending strength, deformation capacity and impact resistance greatly improved. Fiber concrete is the current rapid development of new composite materials at home and abroad, which mixes the development of fiber concrete for the prominent.

Performance of steel fiber reinforcement

1. bonding, steel fiber and concrete interface bonding is basically by physical, should be the fiber surface and fiber shape of the two aspects to improve its bonding properties.

2. Higher hardness, concrete reinforcement for mixing rarely bending phenomenon, if the steel fiber is too hard or too brittle mixing is also relatively easy to break, so it will affect the enhancement effect.

3. corrosion resistance, steel fiber concrete is mainly the use of post-crack arc and post-crack toughness, crack width than reinforced concrete is small, but there will still be cracks, so you have to choose a larger diameter of steel fibers, to improve its corrosion resistance.

Steel fiber applications and advantages

Steel fiber reinforcement is mainly used in the manufacture of steel fiber concrete, and any method of producing steel fiber can play a role in strengthening concrete.

The application of steel fiber reinforcement in flooring is mainly to play the effect of replacing steel reinforcement. Steel fiber in industrial flooring plays a role in improving the crack resistance, impact resistance and fatigue resistance of concrete. Steel fiber plays a good maintenance role in the later maintenance, because steel fiber is generally mixed in the concrete, when the concrete is cracked because the fiber appearance has a fine texture so that it can play a role of coupling, so that it can play a good role of connection. Steel fiber is widely used because the fiber can not only be useful to enhance the compressive strength, tensile strength, flexural strength, impact strength, resistance, impact resistance and other functions, but also has a good corrosion resistance.
