STRUCTURE REPAIRING METHOD
Provided is a structure repairing method capable of ensuring, when being used for a concrete structure, a short construction period and high reliability in a wide temperature range. The structure repairing method comprises: a first restorative layer forming step for forming a first restorative layer by applying a radical-polymerizable resin composition (A) on a structure; a second restorative layer forming step for forming a second restorative layer by, before curing the first restorative layer, applying a restorative material (X) containing a radical-polymerizable resin composition (Ax) and a filler (B) on the first restorative layer; a restorative layer curing step for curing the radical-polymerizable resin composition (A) and the radical-polymerizable resin composition (Ax), wherein, said (A) and (Ax) each contain a radical-polymerizable resin (a1), a radical-polymerizable unsaturated monomer (a2), a hydroxyl group-containing aromatic tertiary amine (a3), and an organic peroxide (a4), and the percentage content of the total of said (a1) and (a2) in each of the (A) and (Ax) is not less than 75 mass%.
本发明提供一种在应用于混凝土结构物的情况、在大温度范围内能够确保短工期并且高可靠性的、结构物的修补方法。包含以下工序：将自由基聚合性树脂组合物(A)涂布在结构物上形成第1修复层的第1修复层形成工序；在使第1修复层固化前，在第1修复层上涂布含有自由基聚合性树脂组合物(Ax)和填充材料(B)的修复材料(X)而形成第2修复层的第2修复层形成工序；以及使自由基聚合性树脂组合物(A)和自由基聚合性树脂组合物(Ax)固化的修复层固化工序，所述(A)和所述(Ax)中都含有：自由基聚合性树脂(a1)、自由基聚合性不饱和单体(a2)、含有羟基的芳香族叔胺(a3)、以及有机过氧化物(a4)，所述(A)和所述(Ax)中所述(a1)和(a2)的合计含有率为75质量％以上。
