1、 What is steel fiber reinforced concrete?
Steel fiber reinforced concrete is a type of concrete reinforced with steel fibers, and the mass percentage of steel fibers is usually controlled between 0.5% and 2.5%. Compared with traditional concrete, steel fiber reinforced concrete has better crack resistance, impact resistance and other properties, making it suitable for engineering structures with high strength, durability and reliability requirements.
2、 The role of steel fibers in concrete
Steel fiber is a component other than steel reinforcement, which plays a role in enhancing the strength, toughness, and durability of concrete. The addition of steel fibers can improve the tensile properties of concrete, increase its crack resistance, reduce its shrinkage deformation, and enhance its durability.
3、 Will steel fiber reinforced concrete experience rusting issues
Steel fibers in steel fiber reinforced concrete may experience corrosion when exposed to air and water. However, due to the generally small diameter and uniform distribution of steel fibers, even if corrosion occurs, the overall impact is very limited.
In addition, steel fiber reinforced concrete usually has a longer mixing time and stronger bonding between steel fibers and concrete. Therefore, even if the steel fibers undergo localized corrosion, it will not affect the structural strength of the entire concrete.
4、 How to avoid corrosion of steel fiber reinforced concrete
To prevent corrosion of steel fiber reinforced concrete, the following measures can be taken:
1. Choose steel fibers with certain corrosion resistance, such as stainless steel fibers.
2. Control the moisture content of concrete to prevent it from getting damp.
3. Control the acidity and alkalinity of concrete to prevent it from being corroded by acid and alkali.
In summary, although steel fiber reinforced concrete may experience corrosion when exposed to air and moisture, as long as steel fiber materials are selected reasonably, concrete quality is strictly controlled, and appropriate anti-corrosion measures are chosen, the corrosion problem of steel fiber reinforced concrete can be effectively avoided or reduced, thereby ensuring the safety of the structure.
