Research on Fiber Shotcrete for Underground Engineering

Abstract:

Article Preview

The fiber material generally has higher tensile strength and toughness, which make up for the lack of tensile strength of concrete and the defects of drying shrinkage easily. Fiber reinforced shotcrete has many engineering advantages such as the crack resistance, impermeability, corrosion resistance (except for steel fiber addition), anti-fatigue performance, wear resistance, impact resistance, toughness and so on. In the construction of tunnels and other underground tunnel, the fiber shotcrete has been more widely used. Fiber materials currently include steel fibers and polypropylene fibers, each with its advantages and adaptability. The mechanism and characteristics of fiber reinforced shotcrete are described to provide an important basis for design and construction of sprayed concrete for underground engineering.
