SDS-1823 0.18-0.23mm Diameter 13±1mm Length Copper Micro Steel Fiber

图片
  Micro steel  fibers are made of copper-coated steel wire. Micro steel fiber wire  is one of most important material of RPC and UHPC.UHPC has high strength, high toughness, very good durability and volume stability. This micro steel fiber  is an excellent new building material. Micro filament steel fibers are currently widely used in high-speed railways, highways, RPC cover plates and UHPC buildings.   If you are interested in our micro steel fiber products, don't hesitate to contact us!   The Specification of SDS-1823 0.18mm-0.23mm Diameter 13±1mm Length Copper Micro Steel Fiber   The Advantages of SDS-1823 0.18mm-0.23mm Diameter 13±1mm Copper Micro Steel Fiber   Good dispersion in concrete; Less impact on UHPC liquidity; Improving the toughness of concrete; The brass fibers provides good impact, fatigue, shrinkage control and ductility in all grade concretes;   USER'S GUIDANCE Dosage: depend on the application and minimum dosage is 120kg/ ...

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...
