Abstract: A cathode protection method for reinforced concrete structure includes steps of: a. removing loose concrete within a protection area, and filling adhesive materials with conductive ability into cracks of a concrete; b. implanting CFRP member as a impressed current auxiliary anode material into the concrete, and spacedly arranged the CFRP member with steel reinforcing elements within the concrete; c. coating adhesive materials on a side of the CFRP member, and firmly pressing the adhesive materials to bonding the CFRP member and the concrete with each other; and d. electrically connecting the steel reinforcing elements and the CFRP member to a negative electrode and a positive electrode of an external DC power supply respectively, such that the concrete, the steel reinforcing element, the CFRP member, and the external DC power supply generate serially-close conductive circuit.
