Glued Steel Fiber for Tunnel

Glued steel fiber is an alternative concrete reinforcement material. It is a high-strength steel wire with hooks at the ends, bonded together by a water-soluble adhesive, and densely and evenly dispersed in the concrete, improving the performance of the concrete by 3-4 times. Steel fiber concrete suppliers improve the mechanical properties of concrete and materials such as ductility, energy absorption, fatigue and toughness. Fibers help control plastic shrinkage cracks in concrete; help reduce or eliminate the need for traditional reinforcement.

Glued steel fiber refers to loose steel fibers bonded together and is made from low carbon steel wire to high carbon steel wire. It has excellent tensile, bending and shear strength, high toughness, crack resistance, impact resistance and fatigue resistance.

Reduce the occurrence of cracks: The crack resistance of steel fibers can effectively control shrinkage cracks in concrete, improve the crack resistance of concrete, and reduce tunnel maintenance and repair costs.

Improve construction efficiency: The convenience of construction makes the application of glued steel fibers in tunnel projects more convenient, speeds up the construction progress, and improves project efficiency.

Glue-coated hook-shaped steel fibers: Single hook-shaped steel fibers are bonded together with water-soluble glue to make the steel fibers disperse evenly without gobs.

First dispersion: Place the steel fibers on the conveyor, and the bonded steel fibers will be dispersed to all corners as a whole.

Secondary dispersion: After the first dispersion, the water-soluble glue begins to dissolve, and the entire glued steel fibers in each corner begin to disperse and become many single steel fibers, Then, a three-dimensional mesh is formed to add reinforcement.
