Steel-continuous basalt composite reinforcement (SFCB)
Steel-continuous basalt composite reinforcement (SFCB) is made of inner steel core and outer longitudinal FRP composite, which has the complementary advantages of high ductility of steel reinforcement and high strength of FRP reinforcement. Its high modulus, high tensile strength, high corrosion resistance, stable and reliable "secondary stiffness" in the structure, and excellent ductility and energy consumption capacity, small residual displacement after the earthquake, easy to repair and other characteristics. It is mainly used in civil construction, transportation and other engineering fields to strengthen the seismic structure of concrete, with the complementary advantages of steel and FRP reinforcement, high modulus, high tensile strength, especially strong corrosion resistance. It is used in various types of concrete structures using SFCB mixed with ordinary steel reinforcement as the main reinforcement.

Product description
Steel-continuous basalt composite reinforcement (SFCB) is made of inner steel core and outer longitudinal FRP composite, which has the complementary advantages of high ductility of steel reinforcement and high strength of FRP reinforcement. Its high modulus, high tensile strength, high corrosion resistance, stable and reliable "secondary stiffness" in the structure, and excellent ductility and energy consumption capacity, small residual displacement after the earthquake, easy to repair and other characteristics. It is mainly used in civil construction, transportation and other engineering fields to strengthen the seismic structure of concrete, with the complementary advantages of steel and FRP reinforcement, high modulus, high tensile strength, especially strong corrosion resistance. It is used in various types of concrete structures using SFCB mixed with ordinary steel reinforcement as the main reinforcement.
SFCB is made of mixed FRP outer cladding layer wrapped around the inner core of steel reinforcement; SFCB composite reinforcement is located within the protective layer of cast-in-place concrete structure, and the hoop reinforcement surrounds the steel-continuous fiber composite reinforcement along the ring, and the skeleton is formed between them by tying or welding; after the SFCB composite reinforcement is prefabricated, then the outer surface of the mixed FRP outer cladding layer of SFCB is treated for bond control. Finally, it is poured inside the main body of concrete structure.
