    摘要： 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. The procedure of the repair method using the surface-penetration reinforcing agent is varied depending on the aging grade of reinforced concrete structure to enhance the strength of the aged reinforced concrete structure and efficiently block the introduction of aging factors into the aged reinforced concrete structure from the outside, so that the endurance life and service life of the aged reinforced concrete structure can be prolonged.

    摘要： Disclosed herein is a penetration reinforcing agent for preventing aging of concrete. The penetration reinforcing agent is prepared by using an inorganic silicate compound having an ethoxy or methoxy group and a monomer having a hydroxyl (OH) group. When the penetration reinforcing agent is applied onto the surface of a concrete structure by using a spray gun or a brush, it penetrates the concrete structure where it is hydrolyzed by water existing within the concrete to form silica (SiO2) having a particle size of several nanometers, is gelled by a sol-gel process and reacts with concrete hydrates, so that internal pores of the concrete structure are compactly filled with the reaction products. Therefore, the penetration reinforcing agent is effective in enhancing the strength of the concrete structure, inhibiting penetration of aging factors into the concrete structure, improving waterproofness of the concrete structure and preventing neutralization of the concrete structure. Further disclosed are a process for preparing the penetration reinforcing agent and a method of applying the penetration reinforcing agent onto concrete.
