Steel Fibers For Shotcrete

 Steel fiber for sfrs shotcrete

 

Steel fibre reinforced shotcrete(SFRS-steel fiber reinforced shotcrete) is referred to as "steel shotcrete", which is similar to plain shotcrete (short for plain shotcrete without steel fiber) and has the following characteristics:

 

1. High strength (tensile, bending and shear), High resistance to impact, explosion and vibration.

 

2. Good toughness (deformability), good frost resistance, heat resistance and fatigue resistance; Strong crack resistance.

 

3. Even if the component has produced tiny cracks, the toughness will be greatly improved because the steel fiber continues to pull out.

 

4. The fiber direction after spraying is close to two-dimensional distribution, and the construction speed is fast and the adaptability is wide.

 

5. The rebound rate of steel shotcrete aggregate is lower than that of plain shotcrete, and the comprehensive unit price of fibre steel shotcrete is lower, so steel shotcrete can replace the traditional shotcrete net support in NATM.

 

SDS, as an excellent steel fiber supplier, offers a wide range of steel fiber products for you to choose from.

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...
