Document Type and Number:
Japanese Patent JP7373351
Kind Code:
B2
Abstract:
To provide a repairing method of a concrete structure set in a high temperature environment or in an environment with relatively large temperature change, and a repairing method capable of enhancing durability of a repaired part.SOLUTION: When repairing a concrete structure exposed to a high temperature environment by filling or covering a repairing part removed of deteriorated parts of the concrete structure with a cross section repairing material containing cement and aggregate, a linear expansion coefficient of concrete of the repairing part is measured or calculated, the cross section repairing material having approximation to the linear expansion coefficient is selected or prepared, and is used as the cross section repairing material.SELECTED DRAWING: Figure 1
