Abstract
There is provided a method for repairing or reinforcing a structure. The method includes the steps of: providing an adhesive sheet comprising an adhesive layer comprising at least a curable resin composition whose curing is promoted by irradiation with ionizing radiation and a curing aid which generates a basic substance by irradiation with ionizing radiation; attaching the adhesive sheet to a surface of the structure; and curing the adhesive layer of the adhesive sheet in a state where the adhesive layer is exposed.
Claims14
A method for repairing or reinforcing a structure by using an adhesive sheet comprising an adhesive layer, the method comprising the steps of:
- applying a primer layer to an entire surface of the structure to be repaired or reinforced, the primer layer comprising an epoxy resin and a polyamine-based curing agent;
- providing the adhesive layer having a composition comprising:
- a curable resin whose curing is promoted by irradiation with ionizing radiation to form a cured resin;
- and
- a curing aid which is a base-generating compound that generates a basic compound by irradiation with ionizing radiation;
- attaching the adhesive sheet to the primer layer;
- and
- curing the adhesive layer in a state where the adhesive layer is exposed.
