Application of steel fiber reinforced concrete

1 water conservancy engineering. Steel fiber reinforced concrete is widely used in hydraulic engineering, is mainly used by the high-speed water stress as well as part of more complex, such as drainage holes, the spillway dam impervious panel, and slope protection, these parts of tensile strength of concrete material, its shear strength andcrack resistance of the relatively high requirements, are played steel fiber concrete’s own advantage.

The 2 construction engineering. The proportion of steel fiber reinforced concrete in construction engineering is more and more big, generally used for housing construction, precast pile engineering, frame joints, the roof waterproof engineering, underground waterproof engineering and other engineering field. Such as: the use ofsteel fiber concrete in seismic frame, can replace the reed gluten strength meet the requirements of ductility,energy dissipation node, etc., but also can provide similar reed gluten confined concrete role, and solve problems in construction of node area reed gluten extrusion casting concrete to.

3 Road and bridge engineering. Steel fiber reinforced concrete in road and bridge engineering, are widely used inroad, bridge, airport runway and other projects, including new and repair engineering. Steel fiber concrete is agood toughness, impact resistance, fatigue resistance. It can make the surface layer thickness is reduced, the expansion joint spacing is lengthened, the use of performance improvement, reduce repair cost, prolong life.

4 railway engineering. In Railway Engineering, steel fiber reinforced concrete is mainly used in the repair andrailway bridge deck waterproof protective layer of double block of steel fiber reinforced prestressed concreterailway sleeper, rail sleeper. Railway Engineering under load, higher speed and tens of thousands of times the vibration, impact resistance, high strength concrete so requirements must have higher and higher plasticity. This is the use of the impact resistance of steel fiber concrete and good plasticity.

5 port and marine engineering. The use of steel fiber concrete in marine engineering is the main corrosionproblems of steel fiber reinforced concrete, so it needs further study, but the use of experience is encouraging in japan. Such as the Japanese steel club adopts steel fiber concrete as the anti-corrosion of steel pipe pile layer,soaked in salt water for 10 years, steel fiber reinforced concrete corrosion intact, non rust steel surface, there is still a metallic luster.

In addition to these areas, there are many examples of the application of steel fiber concrete, such as the bearheavyweight work manufacturing industry workshop, warehouse storage structure of thin ground oh, prefabricated plate, centrifuge tube, bilge well, pool, refractory concrete and refractory material, blast resistant structure, all kinds of buildings and building repair, strengthening, seismic reinforcement.
