The present invention relates to a repair mortar for preventing neutralization of a concrete structure, which adds a neutralization prevention component to a concrete cross-section recovery and repair mortar which is generally used, and to a repair method for preventing neutralization of a concrete structure using a polymer adhesive. The repair mortar for preventing neutralization of a concrete structure of the present invention comprises 30 to 40 parts by weight of alumina cement, 50 to 60 parts by weight of silica, 3 to 7 parts by weight of calcium carbonate, 3 to 5 parts by weight of VAE re-emulsified powder polymer, 3 to 5 parts by weight of an inorganic adhesive, 0.5 to 1 part by weight of silicone powder, 0.3 to 1 part by weight of water-repellent powder, 0.3 to 1 parts by weight of triethanolamine (TEA), 0.01 to 2 parts by weight of a fluidizing agent, and 0.01 to 2 parts by weight of a thickener. The repair method for preventing neutralization of a concrete structure using a polymer adhesive including 35 wt% of an acrylic emulsion having 45 wt% of solid content, 15 wt% of an EVA emulsion having 55 wt% of solid content, 0.5 wt% of an acrylic-based thickener, and 49.5 wt% of water, is provided.
