| titleOfInvention | Shrinkage-reducing ultra high early strength and early strength cement concrete composition and repairing method for road pavement using the same |
| abstract | The present invention comprises 20 to 50% by weight of fine aggregate, 10 to 40% by weight of coarse aggregate, 10 to 40% by weight of a functional improving binder, 0.5 to 20% by weight of a functional improving admixture, and 0.1 to 5% by weight of water; The function-improving binder includes 100 parts by weight of crude steel portland cement, 20 to 40 parts by weight of calcium sulfoaluminate, 1 to 20 parts by weight of potassium nickel cobalt fluoride, 1 to 20 parts by weight of fine blast furnace slag powder, 0.1 to 10 parts by weight of ladle slag, oxidized 0.1 to 10 parts by weight of tin, 0.1 to 10 parts by weight of potassium hexafluoromanganate, and 0.1 to 10 parts by weight of spicule; The function-improving admixture is 100 parts by weight of acrylic latex, 70 to 90 parts by weight of polymethyl methacrylate-(adamantyl) acrylate copolymer, 50 to 70 parts by weight of hydroxyfluorine (meth)acrylate, and Formula 1 below. By using a compound containing 10 to 30 parts by weight of the indicated 2-thio-4-amino pyrimidine derivative, 0.1 to 10 parts by weight of bio-heavy oil, 0.1 to 10 parts by weight of limocitrin, and 0.1 to 10 parts by weight of apigenin; It is possible to secure early strength and improve physical properties such as strength, as well as prevent initial cracking and expansion fracture, as well as shrinkage-reducing early steel and crude steel cement concrete composition with greatly improved properties required for pavement and the same It relates to the road pavement maintenance and repair method used. [Formula 1] In the above formula, R 1 is alkyl having 1 to 6 carbon atoms or (alkyl having 1 to 6 carbon atoms)amine, R 2 is (alkyl having 1 to 6 carbons)amino(alkyl of 1 to 6 carbons)amine or piperidinyl (alkyl of 1 to 6 carbons)amine, X is F or Cl. |
