Title:
REPAIR METHOD OF CONCRETE STRUCTURE
Document Type and Number:
Japanese Patent JP2023138030
Kind Code:
A
Abstract:
To provide a repair method of a concrete structure capable of improving adhesiveness of repair material on a surface of the concrete structure to be improved.SOLUTION: A repair method of a concrete structure 100 includes a step 20 (a first application step) applying solution including bivalent or more cation on a surface of concrete to be repaired. A step 30 (a second application step) applies a composition including silicate aqueous solution after the step 20. A step S40 (an attaching process) attaches repair material 10 which is made by coating or impregnating a composite silicate aqueous solution and pozzolan activity material on/in a laminated body 4 on the surface of the concrete after the step S30. A step S50 (a curing step) cures the repair material 10 after the step S40.SELECTED DRAWING: Figure 3
