▎ 摘  要

NOVELTY - Composition comprises 10-80 wt.% fine aggregate, 10-80 wt.% functional inorganic filler that retains necessary water, 1-20 wt.% performance recovery functional admixture, and 5-35 wt.% water. The functional inorganic filler comprises 10-30 pts. wt.% blast furnace slag, 10-30 pts. wt.% fly ash, 10-30 pts. wt.% calcium sulfoaluminate, 10-30 pts. wt.% kaolinite, 5-15 pts. wt.% titanium dioxide powder, 0.1-5 pts. wt.% graphene oxide and 0.1-5 pts. wt.% zeolite based on 100 pts. wt.% early strong portland cement. The performance recovery functional admixture comprises 15-35 pts. wt.% diaminodiphenylsulfone, 10-20 pts. wt.% acrylonitrile-butadiene-styrene copolymer, 10-20 pts. wt.% polynorbornene copolymer (I), 1-10 pts. wt.% poly(propylene glycol)bis(2-aminopropyl ether) (II), 0.1-5 pts. wt.% polyoxypropylene carboxylate methacrylate, and 0.1-5 pts. wt.% sulfide-based silane coupling agent based on 100 pts. wt.% diglycidyl ether of bisphenol A. USE - The composition is useful in highly functional mortar for repairing and reinforcing concrete structures (claimed). ADVANTAGE - The composition: has excellent performance recovery function, necessary moisture retention function and crack inhibition performance; excellent waterproof, water resistance, chemical resistance, weather resistance, surface hardness, freeze-thaw, resistance to salt damage and antibacterial effect; excellent strength performance i.e. excellent adhesion strength, flexural strength, tensile strength and compressive strength; continuously increases strength; prevents degradation in durability; maintains high durability of deodorization and non-combustible performance for long period of time; provides quick hardening and wet hardening performance; maximizes repair and reinforcing effect of concrete structure; minimizes additional defects; and is economical. DETAILED DESCRIPTION - Composition comprises 10-80 wt.% fine aggregate, 10-80 wt.% functional inorganic filler that retains necessary water, 1-20 wt.% performance recovery functional admixture, and 5-35 wt.% water. The functional inorganic filler comprises 10-30 pts. wt.% blast furnace slag, 10-30 pts. wt.% fly ash, 10-30 pts. wt.% calcium sulfoaluminate, 10-30 pts. wt.% kaolinite, 5-15 pts. wt.% titanium dioxide powder, 0.1-5 pts. wt.% graphene oxide and 0.1-5 pts. wt.% zeolite based on 100 pts. wt.% early strong portland cement. The performance recovery functional admixture comprises 15-35 pts. wt.% diaminodiphenylsulfone, 10-20 pts. wt.% acrylonitrile-butadiene-styrene copolymer, 10-20 pts. wt.% polynorbornene copolymer of formula (I), 1-10 pts. wt.% poly(propylene glycol)bis(2-aminopropyl ether) of formula (II), 0.1-5 pts. wt.% polyoxypropylene carboxylate methacrylate, and 0.1-5 pts. wt.% sulfide-based silane coupling agent based on 100 pts. wt.% diglycidyl ether of bisphenol A. R=dichlorophenyl; x and y=1-10000; and n=1-10. An INDEPENDENT CLAIM is also included for repair and reinforcement construction method of concrete structure comprising (A) removing lattice, impurities or deterioration of the concrete structure by chipping with chipping device, cleaning, (B) primer treatmenting on the cleaned background, (C) finishing surface by pouring highly functional mortar composition for repair and reinforcement of concrete structures, which has excellent performance recovery function and necessary moisture retention function, on primer-treated surface,(D) finishing surface by applying surface protection and strengthening coating agent to finished surface and (E) curing.
