PURPOSE: A permeable inorganic repairing material composition comprising alkali-based silicate, TiO2-sol, silica-sol and permeable surfactant is provided to protect concrete construction resulting from waterproofing and rust prevention, and repair cracking and water leakage parts of construction without crushing. CONSTITUTION: The permeable inorganic repairing material composition comprises 10-35wt.% of sodium silicate with a SiO2/Na2O mole ratio of 3.4 or more, 2.5-22wt.% of lithium polysilicate, 20-30wt.% of colloidal silica with 5-20 nanometer size, 0.1-1.5wt.% of TiO2 sol, 0.05-0.35wt.% of permeable surfactant based on non-ionic or anionic fluoride, and optionally anti-gelation agent.
