<p>PURPOSE: A mortar composition for an eco-friendly organic/inorganic hybrid repairing material and a repairing method using the same are provided to improve the adhesive and the permeability of the organic/inorganic hybrid repairing material and reduce environmental contamination. CONSTITUTION: A mortar composition for an eco-friendly organic/inorganic hybrid repairing material includes 35 to 40 parts by weight of hydraulic cement, 45 to 50 parts by weight of recycled fine aggregate, 8 to 10 parts by weight of artificial lightweight aggregate, 3 to 5 parts by weight of fly ash, 1.65 to 2.45 parts by weight of a PVA powder resin, 0.8 to 1.5 parts by weight of amorphous C12A7-based early hardening accelerator, 2.0 to 2.5 parts by weight of calcium-sulfo-aluminate expanding agent, 0.5 to 1.0 parts by weight of a carbon fiber reinforcing agent, 0.3 to 1.0 parts by weight of a coagulation retarder, 25 to 50 parts by weight of water. The hydraulic cement is one or more selected from normal Portland cement, white Portland cement, alumina cement, early strengthening Portland cement, and high early strengthening cement. The coagulation retarder is selected from natural gypsum, dihydrate gypsum, hemihydrate gypsum, or anhydrous gypsum.</p> |
