The polymeric admixture comprises 5 to 70% by weight of an inorganic binder containing an inorganic pigment, 25 to 85% by weight of a fine aggregate, 0.01 to 20% by weight of a polymer admixture and 0.1 to 20% Wherein the mortar composition comprises 50 to 99% by weight of butadiene, 0.1 to 20% by weight of polymethyl methacrylate, 0.1 to 20% by weight of silicate resin, and 0.1 to 20% by weight of silane resin. To a method of repairing a concrete structure. According to the present invention, it is possible to provide a method for recovering a cross-section of a bridge, a sewer culvert, a neutralized underground roadway, a tunnel restored after the occurrence of a topic, and a highway structure suffering from salinization caused by a fusing agent because of excellent strength and durability, Improvement of durability and visibility of all concrete structures such as maintenance finishing works, finishing of concrete piers of railway bridges, finishing of newly constructed concrete bridges, concrete finishing works outside buildings, underground parking lots, water treatment plants and sewage treatment plant structures And can be used for automation equipment. Therefore, it is possible to provide a convenient construction, economical efficiency by shortening the construction time and labor cost, maintaining excellent construction quality, and drastically reducing maintenance cost, Fine aggregate mixed with dolomite excellent in strength, abrasion resistance and fire resistance Use is excellent in strength, abrasion resistance, and fire resistance by landscapes harmony. |
