Abstract

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 supplying a modifying agent being performed before the step of supplying the concrete protective agent to promote production of the calcium silicate in step of supplying the concrete protective agent.

Abstract

This concrete protective material contains a silicate containing an alkali metal and an alkaline electrolyzed water. Alternatively, this concrete protective material contains a silicate containing an alkali metal and silicon dioxide. Examples of the silicate containing an alkali metal include sodium silicate, potassium silicate and lithium silicate. A concrete structure is able to be repaired by supplying this concrete protective material to the concrete structure. Consequently, the present invention provides a concrete repairing agent which exerts a larger repair effect than conventional concrete repairing agents.

Abstract

Provided is a modifying agent for a concrete structure, and a manufacturing method for same, that makes the operation of modifying the concrete structure simple and safe for the human body, and also can impart high durability to the concrete structure. Further provided is a method for repairing a concrete structure that can be performed more efficiently and in less time than prior methods for repairing a concrete structure. The modifying agent for a concrete structure is an alkaline electrolyzed water. Calcium ions are dissolved in the alkaline electrolyzed water. The alkaline electrolyzed water has a pH of, for example, 11 or higher.
