CONCRETE CONSTRUCTION REPAIR STRUCTURE AND CONCRETE CONSTRUCTION REPAIR METHOD

摘要

PROBLEM TO BE SOLVED: To provide a concrete construction repair structure which has functions to repair crack and to relatively easily confirm a stress state after repair.SOLUTION: A concrete construction repair structure comprises: a low viscosity substrate material 2 which is applied to and infiltrated into a crack generated on a concrete construction 1; a high viscosity adhesive material 3 which is applied on top of the substrate material 2; and a fabric sheet 4 adhered to the concrete construction through the adhesive material 3. The substrate material 2 contains a stress luminous body 10 which produces luminescence with a change in stress. The adhesive material 3 or a finish coating material of the fabric sheet 4 may contain the stress luminous body 10.SELECTED DRAWING: Figure 1
