Hooked End Steel Fiber for Tunnel

Hook -end steel fiber is a material that is widely used in tunnel projects. The hook end design enables the fiber to better anchor the concrete, thereby providing better strength and durability. This material has the following applications:

1. Prefabricated concrete products: Add steel fiber to prefabricated concrete products, such as fixed walls, pipelines and obstacles to improve its strength and durability in transportation and treatment.

2. Tunnel lining: Add steel fiber to the concrete used in the tunnel lining to improve its stress and resistance to the surrounding soil. This helps to prevent rupture and ensure the life of the structure.

3. Bridge: often add steel fiber to the bridge structure to improve the concrete that improves its strength and durability, and prevent rupture and reduce maintenance costs.

4. Mixing: When the sand and clusters are poured into the fight, the appropriate amount of loose steel fibers are evenly mixed, and then the cement is added. Put it on the mixed table, dry and mix for 2 minutes. If you stick it to a row of steel fibers, you need to add steel fiber after adding water to allow the water to dissolve adhesive glue. When adding steel fibers, gloves and eye protection should be used.

Q1: What is the role of steel fiber in the soil?

1. Ordinary concrete: It has compression characteristics, but it is a crispy material without crack toughness. In the structural calculation, the stretch strength of the ordinary concrete itself is not considered.

2. Concrete reinforcement: CIT of the steel rod or steel mesh, reinforcement of prestressed reinforcement reinforced by steel fiber.

3. Steel fiber reinforced concrete: multi -phase composite building material. Compared with ordinary concrete, the main advantage is stretching strength and bending strength. And shear strength, impact force.

Q2: What is hook -end steel fiber?

Hook -end steel fiber is a kind of steel bars used to improve its strength and durability. They are made of high -intensity steel wires and have a hook end, which helps to anchor them in the concrete matrix. The hook at the end of the fiber prevents them from pulling out of the concrete, thereby improving their validity of improving the toughness and delay of concret.
