Steel fibers can be added to concrete used as boosters. The toughness of concrete with steel fiber is high, but the durability is good, the application range is greatly improved. Adding a small amount of fiber can improve the crack resistance, impact resistance compressive strength of concrete. The reinforcement program can also damage to control it, prevent it spreading reduce damage. The fiber looks like a crescent shape. This shape can be very good. A single steel fiber is embedded in the fiber, which greatly increases its strength the steel surface is very rough. It can be well combined with concrete, the effect is amazing.
