STRUCTURE REPAIRING METHOD
Provided is a structure repairing method which, when applied to concrete structures, ensures a short construction period and high reliability in a wide temperature range. The structure repairing method includes a first repairing layer forming step of applying a radical-polymerizable resin composition (A) to a structure to form a first repairing layer, a second repairing layer forming step of applying a repairing material (X) containing a radical-polymerizable resin composition (Ax) and a filler (B) to the first repairing layer before the first repairing layer is cured, thereby forming a second repairing layer, and a repairing layer curing step of curing the radical-polymerizable resin composition (A) and the radical-polymerizable resin composition (Ax), wherein (A) and (Ax) each contain a radical-polymerizable resin (a1), a radical-polymerizable unsaturated monomer (a2), a hydroxy group-containing aromatic tertiary amine (a3), and an organic peroxide (a4), and the total content of (a1) and (a2) in each of (A) and (Ax) is 75% by mass or more.
