摘要
The present invention relates to a performance-improving super-fast cement comprising 5 to 45% by weight of a performance improving binder, 10 to 75% by weight of fine aggregate, 7 to 65% by weight of coarse aggregate, 0.01 to 25% by weight of a performance improving admixture, and 0.1 to 30% by weight of water. A concrete composition comprising: The performance-improving binder is 100 parts by weight of crude Portland cement, 20 to 40 parts by weight of calcium sulfoaluminate, 1 to 20 parts by weight of copper carbonate, 1 to 20 parts by weight of blast furnace slag, 0.1 to 10 parts by weight of zinc cyanurate, and tin oxide 0.1 to 10 parts by weight, 0.1 to 10 parts by weight of cerium aluminide, and 0.1 to 10 parts by weight of sericite; The performance improvement admixture is 100 parts by weight of acrylonitrile-butadiene-styrene copolymer, 70 to 90 parts by weight of ethylene-glycidyl methacrylate copolymer, 10 to 30 parts by weight of diacetone acrylamide, using a compound containing 0.1 to 10 parts by weight of Phloretin sulfonate and 0.1 to 10 parts by weight of polyrotaxane; It relates to a performance-improving ultra-fast cement concrete composition useful for excellent emergency repair work, has excellent workability, and has excellent durability such as waterproofness, freeze-thaw, neutralization and salt damage, and a road pavement maintenance method using the same.
