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.

Abstract: A cathode protection method of embedded CFRP anode for reinforced concrete structure includes the following steps. Provide a preformed groove with a predetermined shape and size in a surface of a protection area of a reinforced concrete body, and remove dust in the preformed groove. Provide a CFRP member on the surface of the protection area of the reinforced concrete body. Coat an electrical conductive adhesive material between side surfaces of the reinforcing column of the CFRP member and the preformed groove and between the reinforcing plate and the reinforced concrete body. Connect the CFRP member with a positive electrode of an external DC power supply and the steel reinforcing element with a negative electrode of the external DC power supply.
