Quick-hardening concrete composite and repairing method for concrete pavement using the same
According to a rapid hardening concrete composite and a repairing method for concrete pavement using the same, the rapid hardening concrete composite is formed by mixing 17 to 20 parts by weight of a rapid hardening concrete-based binder, 48 to 52 parts by weight of fine aggregate, 20 to 40 parts by weight of coarse aggregate, 0.1 to 1 part by weight of hydrophilic fiber, 2 to 3 parts by weight of water, and 4 to 6 parts by weight of a polymer emulsion. The rapid hardening concrete-based binder is formed by mixing 85 to 93 parts by weight of calcium sulfoaluminate, 7 to 15 parts by weight of gypsum powder, 0.05 to 0.5 parts by weight of a silicone-based antifoaming agent, 0.4 to 0.6 parts by weight of tartaric acid, 0.1 to 3 parts by weight of lithium carbonate, and 0.1 to 3 parts by weight of a water reducing agent. The durability of rapid hardening concrete composite can be improved.
