Title:
METHOD FOR REPAIRING CONCRETE STRUCTURE
Document Type and Number:
Japanese Patent JP2023146658
Kind Code:
A
Abstract:
To provide a method for repairing a concrete structure capable of improving the adhesion of a repair material to the surface of the concrete structure.SOLUTION: In the method for repairing a concrete structure 100, a composition containing an aqueous silicate solution is coated on the surface of the concrete to be repaired in step S20 (coating step), a repair material 10 in which a laminate 4 is coated or impregnated with a composition containing an aqueous silicate solution and a pozzolan active substance is pasted on the surface of the concrete after step S10 in step S30 (pasting step), and the repair material 10 is hardened after the step S30 in step S40 (hardening step). The molar ratio of the silicate aqueous solution in the step S30 is greater than or equal to the molar ratio of the silicate aqueous solution in the step S20.SELECTED DRAWING: Figure 3
