SDS Micro Copper Coated Steel Fiber



Micro steel fibers are made of copper coated steel wire, which is the most important materials of RPC and UHPC. UHPC has the features of very high strength, high tenacity, very good durability, and volume stability. It is a good and a new kind of construction materials. Micro steel fiber is widely used in the building of high way, expressway, RPC cover plates, and UHPC construction.





Advantage of Brass Coated Micro Steel Fiber



Performance Advantage

With good dispersion performance in concrete; less impact in UHPC Liquidity and high tensile strength.



Characteristic Advantage

Providing good impact, fatigue, shrinkage control, and ductility in all kinds of concrete.



Material Advantage

Significantly improve the toughness of 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...
