Steel Fibers For Crack Control

 Why we use Steel Fibers For Crack Control?

 

The steel fiber has a high tensile strength of 1000Mpa, which could ensure that the steel fiber will not be broken when working with concrete;

 

The end hooks at both ends of steel fiber manufacturer ensure the best anchor between steel fiber and concrete solid so that steel fiber can effectively transmit and distribute stress, which can effectively control the development of cracks in concrete.

Basic Theory of Steel Fiber Reinforced Concrete

图片
  Steel fiber in concrete mainly restricts the expansion of concrete cracks, so that its tensile, flexural and shear strength are significantly improved compared with ordinary concrete. Its impact resistance, fatigue resistance, post-cracking toughness and durability are also greatly improved. It can make the concrete that was originally a brittle material into a composite material with certain plastic properties.   Ⅰ . The fiber spacing theory of metal fiber concrete   The fiber spacing theory, also known as the fiber crack resistance theory, was proposed by J.P.Romualdi and J.B.Batson in 1963. According to the theory of linear elastic fracture mechanics, the theory explains the restraint effect of fibers on the occurrence and development of cracks. It is believed that in order to increase the tensile strength of concrete, a brittle material with internal defects, it is necessary to reduce the size of internal defects as much as possible and improve toughness. Reduce the...
