Zusammenfassung:The invention discloses a method for reinforcing concrete structures, which is implemented by taking magnesium phosphate cement as a structure adhesive through bonding a layer of carbon fibers on the surface of a concrete structure, so that an effect of reinforcing is achieved. The method is characterized in that the carbon fibers before being bonded on the concrete structure are pretreated, so that a hydration product-ammonium magnesium phosphate hexahydrate with a cementation effect is generated among cellosilks in the carbon fibers. The method disclosed by the invention has the advantages of simplicity in operation, good pretreatment effect, and capability of improving the wettability of the magnesium phosphate cement to fiber cloth, increasing the bonding strength between the magnesium phosphate cement and the carbon fiber cloth, and enhancing the effect of concrete structure reinforcement, and the like.
