Steel Fiber For Fatigue Resistance

Tengzhou Star smith Metal Products Co., Ltd. (SDS）is one of the top three steel fiber manufacturer specializing in steel fiber production in China and has participated in the construction of national projects several times. Established in 2011, we can provide an annual production scale of up to 10,000 tons of steel fiber for concrete. It mainly produces glued steel fiber, copper-coated micro steel fiber and loose steel fibers.

Fatigue resistance of steel fiber compared with ordinary concrete, the flexural and compressive fatigue properties of steel fiber reinforced concrete are greatly improved. For example, when the bending fatigue life is 106 times, the stress ratio of steel fiber reinforced concrete with 1.5% fiber content is 0.68, while that of ordinary concrete is only 0.51.

When the stress ratio is 0.7, the bending fatigue life of steel fiber reinforced concrete exceeds 105 times, while that of ordinary concrete is only 850 times. Another example is: when the compressive fatigue life of steel fiber reinforced concrete with 2% fiber reaches 2*106 times, the specific force can reach 0.92, while the stress ratio of ordinary concrete is only 0.56. It can be seen that the use of steel fiber reinforced concrete can significantly improve its fatigue life in projects bearing fatigue loads such as pavement and pier.
