ABSTRACT:
Disclosed is a surface-penetration reinforcing agent that is used to effectively repair a damaged reinforced concrete structure. The surface-penetration reinforcing agent includes a silicate compound, an acrylate monomer, an amine compound and a silane compound as reactants. Further disclosed is a method for repairing a damaged reinforced concrete structure using the surface-penetration reinforcing agent depending on the aging grade of the reinforced concrete structure. According to the repair method, the surface-penetration reinforcing agent can be used to efficiently repair a damaged reinforced concrete structure depending on the aging grade of the reinforced concrete structure classified by whether or not the reinforcing bars are corroded in damaged portions of the concrete and the degree of carbonation in the concrete.
