The present invention provides a concrete protective agent including an alkali metal-containing silicate and an alkaline electrolyzed water. Alternatively, the present invention provides a concrete protective agent including an alkali metal-containing silicate and silicon dioxide. Examples of the alkali metal-containing silicate include sodium silicate, potassium silicate and lithium silicate. By supplying the concrete protective agent to a concrete structure, the repair of the concrete structure can be performed. Thus, the present invention provides a concrete repairing agent having a significant repairing effect as compared with conventional concrete repairing agents. |
