Alternatively, the concrete protective material includes: an alkali metal-containing silicate; and silicon dioxide. As the alkali metal-containing silicate, e.g., sodium silicate, potassium silicate, lithium silicate or the like can be given. By feeding the concrete protective material to a concrete structure, the repair of the concrete structure can be performed. |
