摘要:
A modifying agent of an alkaline electrolyzed water. A substance being supplied to a concrete structure in order to produce calcium silicate for repairing concrete and including an alkali metal silicate is defined as a concrete protective agent. The modifying agent is supplied to the concrete structure in advance of the supply of the concrete protective agent. The alkali metal silicate and the calcium ion included in the concrete protective agent contribute to the production of the calcium silicate. A method for repairing a concrete structure includes supplying the concrete protective agent to the concrete structure and supplying a modifying agent for a concrete structure including an alkaline electrolyzed water to the concrete structure, the step of supplying a modifying agent being performed before the step of supplying the concrete protective agent to promote production of the calcium silicate in the step of supplying the concrete protective agent.
摘要:
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. 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.
