Steel fiber reinforced concrete Steel Fiber: Steel fiber in concrete functions depend on two aspects: ash Pt and fiber parameters (length Lt, aspect ratio Lf / dF, geometry and tensile strength fsft). Scope of application of steel fiber reinforced concrete: Steel fiber reinforced concrete is a new type of composite material, is widely used in roads, airports, bridges, hydraulic, ports, railways, mines, tunnels, cement covers, and industrial and civil construction such as engineering, applied against the pull, anti - shear, flexural strength and crack resistance, impact resistance, earthquake and blast-resistant, and other performance requirements of high structural engineering or local area. Steel fiber reinforced concrete with the ratio: Steel fiber reinforced concrete mix could be based JG/T3064-1999 "steel fiber reinforced concrete" in terms of design 6.1-6.4. Steel fiber reinforced concrete specifications: * CECS38: 92 "steel fiber reinforced concrete structural design and construction of a point of order" * CECS13: 89 "steel fiber reinforced concrete test method" * JG/T3064-1999 "Steel Fiber Reinforced Concrete"
