摘要:
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.
摘要:
The present invention provides a modifying agent for a concrete structure that allows the modification operation of a concrete structure to be safe for the human body and simple, and is capable of imparting high durability to a concrete structure, and a method for manufacturing the modifying agent. The present invention further provides a method for repairing a concrete structure, capable of efficiently repairing in a shorter time than conventional methods for repairing a concrete structure. The modifying agent for a concrete structure is an alkaline electrolyzed water. The alkaline electrolyzed water includes calcium ions dissolved therein. The pH of the alkaline electrolyzed water is, for example, 11 or more.
