Steel Fiber Introduction 

The steel fiber is a kind of new material which is mixed into the concrete  to reinforce the strength of the concrete. It is a kind of short fiber, to be distributed in the concrete, suppressing the expand and occurrence of the macro-cracks, reducing the brittleness of concrete to improve its durability, comparing to common concrete, the concrete mixed steel fiber mainly appear the following advantage:

Compression strength increased by 8%-10%                   Tensile strength increased by 50%-70%

The shear strength increased by 30%-70%                    The flexural strength increase by 120%-180%

The impact resistance increased by 200%-700%             The fatigue resistance increased by 50%-60%

The wear resistance increased by 25%-35%                  

The steel fiber concrete is widely used in the following projects:

Highway and bridge: Road surface, bridge pavement, bridge arch, continuous box girder placement

Hydraulic dam： Industrial flooring, hydraulic tunnel lining, water erosion wear parts, the hydraulic gate, the hydraulic gate groove, aqueducts, dams and sea infiltration panel

 Railway： Prestressed railway sleeper, double-block railroad ties

Port and ocean engineering： Corrosion layer of steel columns, terminal facilities, undersea concrete facilities

Tunnel and mine engineering： Hydraulic tunnel lining, mine lane, highway and rail tunnel lining

pipeline engineering: Centrifuge tube, vibration and extruded tubes, pump pipe, steel-lined steel fiber reinforced concrete pressure pipes

Other construction engineering： Housing construction, precast, roof underground waterproof, heavy loading industrial floor, maintenance reinforcement engineering, underground cable / pipe wells, mine lane, airport pavement
