  Steel fiber reinforced concrete is a new type of composite material. It has excellent physical and mechanical properties such as tensile, bending, crack resistance, impact resistance, fatigue resistance, and high toughness. At present, steel fiber has been widely used in construction engineering, hydraulic engineering, highway and bridge engineering, highway pavement and airport pavement engineering, railway highway, pipeline engineering, inland waterway engineering, anti-riot engineering and maintenance and reinforcement engineering.   Ⅰ. The application of steel fiber reinforced concrete in hydraulic engineering   It is mainly used for parts subject to high-speed water flow and complex forces, such as spillways, drains, pressure drains, stilling basins, gate bottom plates and sluices, ship locks, aqueducts, dam seepage panels and slope protection, etc. . These parts have relatively high requirements on the tensile strength, shear strength and crack resistance of the c...

  1. S teel fiber reinforced concrete   As the most widely used building material in the current era, concrete has the advantages of good bonding performance with steel bars. But everything has two sides. The shortcomings of concrete are high brittleness and low tensile strength, which also limit the wide application of engineering. Faced with this situation, steel fiber came into being, steel fiber concrete reinforcement  is an important means of concrete modification.   2. Steel fiber reinforced concrete can better solve the problem that ordinary concrete cannot solve   Steel fiber reinforced  concrete can better solve the problems such as cracks and durability that are difficult to be solved by ordinary concrete, improve the use quality of bridge deck, and is also very beneficial to prolong the service life of bridge deck. It will be more widely used in the reinforcement and reconstruction of old highway bridges, bridge deck repair, and bridge defect rep...

  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 glued steel fiber  reinforced 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 i...

  Ⅰ. How does steel fiber reinforced shotcrete   promote the development of urban architecture   The main function of short fibers distributed uniformly and disorderly in steel fiber reinforced concrete is to hinder the expansion of micro-cracks in the concrete and prevent the occurrence of macro-cracks. Therefore, it can significantly improve the tensile strength of concrete and the shear, flexural and torsional strength controlled by the tensile stress. Even in the case of certain cracks in the concrete, it still has a great contribution to the load-bearing capacity of the concrete. Only when the fiber is pulled out of the concrete, the tensile strength will decrease. The improvement of steel fiber on the bending and compressive fatigue performance of concrete is also obvious. Through the study of the basic mechanical properties of steel fiber reinforced concrete , it is found that the addition of steel fiber does not greatly improve the compressive strength of concrete...

  Our lives are inseparable from steel fiber. For example, there are steel fibers on the roadbed of roads and road construction. The role of steel fiber is to strengthen the overall performance of concrete and it is widely used in road paving projects. There are many types of fibers, which also change based on market needs. And the main properties include tensile strength and bond strength. So far, steel fiber has become one of the most commonly used building materials, which can meet the needs of construction projects well.   1. Continuous improvement of steel fiber technology and performance   Steel fiber reinforced concrete produced by concrete fiber manufacturers  is a mixture made by adding fibers to viscous hardened cement mortar. The fiber redistributes the stress in the concrete and inhibits the formation and spread of cracks, making it a steel fiber reinforced concrete that can maintain residual stress after cracking and is more flexible. The fiber's anti-be...

  1. About micro copper coated steel fiber   The wide application of micro-copper-plated steel fiber has exceeded people's expectations, has had a huge impact on the construction industry, and directly promoted the upgrading of construction technology and economic development. The product has high shear, bending and tensile properties with low shrinkage, can effectively prevent cracks, and it is easy to stir. To separate the waterproof layer from the leveling layer and reduce the impact of shrinkage and temperature stress, a certain amount of expansion agent was added to the copper microwire steel fiber concrete to achieve good results.   Copper coated steel wire, produced by concrete fiber suppliers , is one of the most commonly used building materials. If the micro copper coated steel fiber can be evenly mixed in the concrete, the crack resistance will be greatly improved. The durability, abrasion resistance, and frost resistance of concrete will be greatly improved due...

  1. Steel fiber reinforced concrete is good in crack resistance and integrity   The impermeability of steel fiber reinforced concrete is similar to normal concrete. But the freeze-thaw resistance, heat resistance, abrasion resistance, cavitation resistance, and corrosion resistance of steel fiber reinforced concrete all are significantly improved because it has good crack resistance and integrity. For example, the compressive and flexural strength of concrete mixed with 1.5% fiber is reduced by about 20% after 150 freeze-thaw cycles, while ordinary concrete such as steel fiber hooked end  with the same other conditions is reduced by 60%. After 200 freeze-thaw cycles of testing, the steel fiber reinforced concrete pieces remain intact.   2. Application performance of steel fiber reinforced concrete in construction engineering   It is generally used in engineering fields such as housing construction engineering, prefabricated pile engineering, frame joints, roof ...
