In　this　research,　Magnesium　Phosphate　Cement　(MPC)　was　innovatively　used　to　bond　with　Carbon　Fiber　Reinforced　Plastic　(CFRP)　in　order　to　form　the　MPC-CFRP　as　a　composite　material,　adopted　both　for　chloride　ions　extraction　and　reinforcement　of　concrete　columns.　First　of　all,　a　series　of　tests　were　conducted　to　evaluate　the　feasibility　of　the　MPC-CFRP　as　anode　of　Electrochemical　Chloride　Extraction　(ECE)　system,　including　chloride　ions　concentration,　Scanning　Electron　Microscope　(SEM)　and　tensile　strength.　Then,　the　MPC-CFRP　was　used　to　wrap　around　reinforced　concrete　column　for　the　sake　of　reinforcement　and　extraction　of　chloride　ions.　The　test　results　indicated　that　the　chloride　extraction　efficiency　and　the　tensile　resistance　of　the　MPC-CFRP　electrode　were　superior　to　the　control　group.　The　ECE　process　can　decrease　the　interface　bonding　strength　between　the　concrete　and　the　steel　rebar　while　the　compression　resistance　of　the　columns　could　be　increased　remarkably.　Therefore,　the　MPCCFRP　composite　material　is　capable　of　achieving　the　dual　functions　of　strengthening　and　repairing　the　reinforced　concrete　construction.
