The present invention is capable of recovering the cross-sectional recovery and neutralization after repair of concrete damaged by various deterioration phenomena such as neutralization, salting and sulphate erosion, reinforcing the surface layer, expressing initial and long-term strength as well as thickness of 10 mm or more on the ceiling part. It can be installed at a time and can exhibit excellent adhesion performance even in the long term, such as vibration, and provides excellent anti-bacterial and acid-resistant repair mortar composition resistant to bacteria and sulfide gas generated in sewage.n n n To this end, the present invention is a 30.0 to 45.0% cement, 5.0 to 15.0% blast furnace slag or zeolite fine powder, 5.0 to 10.0% calcium carbonate (CaCo 3 ) powder, 0.2 to 1.0% acrylic resin at room temperature, atmospheric pressure conditions (Acrylic Resin), 0.2-1.0% Vinyl Resin, 0.2-1.0% Calcium Sulphoaluminate (CSA) Expander, 1.0-3.5% Calcium Oxide (CaO) -based Expander, 1.0-3.5% Anhydrous Gypsum (Anhydrous Gypsum), 0.1-0.5% Nylon Fiber, 0.1-0.5% Dispersion Agent, 0.1-1.0% Antibacterial and Acid-resistant Admixture, 30.0-45.0% Silica Sand It is characterized by consisting of a mixture in the weight ratio as a component. |
