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.
