摘要

The present invention is a high-performance latex-modified fast-hardening cement concrete composition having improved salt penetration resistance, freeze-thaw resistance and scaling resistance, wherein the fast-hardening binder is 10 to 30% by weight, fine aggregate 30 to 60% by weight, coarse aggregate 20 to 50% by weight , comprising 1 to 20% by weight of a high-performance latex modifier and 1 to 20% by weight of a compounding water, The fast-hardening binder is usually 100 parts by weight of Portland cement, 55 to 75 parts by weight of calcium sulfoaluminate, a fineness of 6,000 to 10,000 cm 2 /g, and an SO 3 content of 55 to 63% by weight of natural anhydride 10 to 30 parts by weight, 10 to 30 parts by weight of chemical anhydride, 1 to 10 parts by weight of zinc oxide, 1 to 10 parts by weight of manganese dihydrogen phosphate, and 0.5 to 5 parts by weight of molybdenum disulfide; The high-performance latex modifier includes 50 to 70% by weight of a core consisting of 60 to 80% by weight of styrene, 10 to 30% by weight of methyl methacrylate, 1 to 20% by weight of (meth)acrylic acid ester, and 0.1 to 5% by weight of methylenebisacrylamide. And, surrounding the core, 60 to 80% by weight of methyl methacrylate, 10 to 30% by weight of styrene, 1 to 20% by weight of (meth)acrylic acid ester, and 0.1 to 5% by weight of manganese dihydrogen phosphate shell 30 to 50% by weight; The latex modifier uses a structure having a concentration gradient in which the composition ratio of styrene continuously decreases from the center of the core to the outer shell of the shell; It relates to a high-performance latex-modified fast-hardening cement concrete composition having improved salt penetration resistance, freeze-thaw resistance and scaling resistance, and a method for repairing bridges and pavements using the same.
