Functional cement mortar composition for repair and reinforcement of concrete structure and repair and reinforcement method of concrete structure using same

摘要

The present invention is a functional cement mortar composition, comprising 24 to 60% by weight of an inorganic binder, 5 to 70% by weight of fine aggregate, 1 to 20% by weight of a functional admixture, and 5 to 25% by weight of water, and the inorganic binder is, the total inorganic binder Based on weight, crude steel Portland cement 20 to 80% by weight, amorphous calcium aluminate 3 to 40% by weight, diatomaceous earth 10 to 35% by weight, silicon nitride 1 to 25% by weight, zirconium boride 1 to 25% by weight, gypsum 1 to 15 Wt%, copper oxide 1 to 10 wt%, aluminosilicate 1 to 15 wt%, sepiolite 0.5 to 10 wt%, beryllium oxide 0.5 to 10 wt%, halosite 0.4 to 10 wt%, hydrophilic fibers 0.4 to 10 It includes weight%, and 0.2 to 10% by weight of a curing retardant, and the functional admixture is 35 to 95% by weight of ethylene vinyl acetate and 0.1 to 15% by weight of nitro-cellulose based on the total weight of the functional admixture. , Cyanoacrylate 0.1 to 25% by weight, ethylene vinyl alcohol copolymer 0.1 to 15% by weight, and polybutylene terephthalate 0.2 to 25% by weight of functional cement mortar for repair and reinforcement of a concrete structure, characterized in that it comprises It relates to a composition and a concrete structure repair and reinforcement method using the composition.
