▎ 摘　　要

NOVELTY - A mortar composition comprises cement, silica sand, swelling agent, aqueous colloidal silica solution, aluminum powder, polycarboxylic acid water-reducing agent containing triethanolamine, reinforcing fibers, magnesium silicate fluoride, calcium oxide and sodium polyacrylate starch, and a mixture of graphene powder and metasilicate. USE - The composition is useful for repairing/reinforcing structure (claimed). ADVANTAGE - The composition has improved acid resistance and corrosion resistance due to salt damage as well as various deterioration factors, and secures strength, workability, and physical properties i.e. workability and strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for repair/reinforcement method using a salt-resistant repair/reinforcement mortar composition. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for repairing/reinforcing structure using mortar composition (Drawing includes non-English language text).
