What is steel fiber? What's the use of it?
Steel fiber reinforced concrete (Steel Fiber Reinforced Concrete SFRC) is a relatively uniform and multidirectional reinforced concrete form by adding a small amount of low carbon steel, stainless steel and glass in the ordinary concrete after fiber. Incorporation of steel fiber by volume is L - 2%, and by weight per cubic meter of concrete with 70 - 100Kg steel fiber, steel fiber length should be 25 60mm, diameter 0.25 1.25mm, the optimal ratio of length and diameter of 50 to 700.
Concrete made of steel fiber is stronger
Compared with ordinary concrete, not only can improve the tensile, shear, bending, anti-wear and anti cracking performance, but also can greatly enhance the fracture toughness of concrete and impact resistance, improve fatigue properties and durability of structures. Especially the toughness can be increased L020 times.
Improve the fatigue performance and durability of structure.
