ADHESIVE COMPOSITION FOR REINFORCEMENT JOINT, CONNECTION REINFORCEMENT, STRUCTURE, AND METHOD FOR MANUFACTURING CONNECTION REINFORCEMENT
PROBLEM TO BE SOLVED: To provide an adhesive composition for reinforcement joint which has quick curability at low temperatures, has good filling properties in a wide temperature range, and can exhibit excellent strength (for instance, compressive strength).SOLUTION: There is provided an adhesive composition which contains (A) monofunctional (meth)acrylate, (B) polyfunctional (meth)acrylate, (C) a thermal radical polymerization initiator, (D) a polymerization accelerator and (E) a filler, where F component is a combination of a filler having an average primary particle size of 10 μm or more and 50 μm or less and a filler having an average primary particle size of 20 nm or less, a ratio of the filler having the average primary particle size of 10 μm or more and 50 μm or less is 90 mass% or more and 98 mass% or less with respect to 100 mass% of the total of the fillers, D component of 0.2-0.6 pts.mass is contained with respect to 100 pts.mass of the total of the A component and the B component, and a content of (E) elastomer is 0-15 pts.mass with respect to 100 pts.mass of the total of the A component and the B component.SELECTED DRAWING: None
【課題】低温での、速硬化性を有し、広い温度範囲で充填性が良く、かつ優れた強度（例えば、圧縮強度）を発揮することができる鉄筋継ぎ手用接着剤組成物を提供すること。【解決手段】（Ａ）単官能（メタ）アクリレート、（Ｂ）多官能（メタ）アクリレート、（Ｃ）熱ラジカル重合開始剤、（Ｄ）重合促進剤および（Ｆ）充填剤を含み、Ｆ成分が、平均一次粒子径１０μｍ以上５０μｍ以下の充填剤と、平均一次粒子径２０ｎｍ以下の充填剤との組み合わせであり、かつ、平均一次粒子径１０μｍ以上５０μｍ以下の充填剤の割合は、充填剤合計１００質量％に対して、９０質量％以上９８質量％以下であり、Ａ成分とＢ成分との合計１００質量部に対してＤ成分を０．２〜０．６質量部含み、Ａ成分とＢ成分との合計１００質量部に対して（Ｅ）エラストマーの含有量が０〜１５質量部である、鉄筋継ぎ手用接着剤組成物。【選択図】なし
