A mortar for recovering deteriorated parts in concrete and a method for recovering deteriorated parts by using the same are provided to increase durability and to inhibit the deterioration of concrete. A mortar for recovering deteriorated parts in concrete comprises 15-35 wt% of portland cement, 2-10 wt% of alumina cement or calcium sulfur aluminate cement, 1-5 wt% of gypsum, 1-5 wt% of silica fume, 3-15 wt% of slag or fly ash, 0.1-2 wt% of mica, 0.05-0.5 wt% of a water-reducing agent, 1-5 wt% of a powdered resin, 0.5-5 wt% of wollastonite, 0.1-0.5 wt% of synthetic fibers, 1-5 wt% of a functional admixture and 30-60 wt% of quartz sands. A deteriorated surface in concrete is recovered by a method comprising the steps of: surface-treating of removing deteriorated parts and foreign matters; coating an alkali recovering agent; coating an anti-corrosive coating agent; coating the mortar-containing composition; and finishing with a fluoropolymer coating agent. |
