REPAIR MATERIAL, CURABLE COMPOSITION SET AND METHOD OF REPAIRING CONCRETE STRUCTURE
To provide a repair material capable of developing sufficient adhesion strength even in high-humidity and wet concrete environments.SOLUTION: A repair material 10 is a repair material used for repairing concrete structures and includes a curing composition, a modifier solution, a densifier solution, and a permeable repair substrate 4. The curing composition includes a solution containing sodium silicate and a pozzolanic active substance. The modifier solution contains more than two cations and nitrate ion and/or nitrite ion. The densifier solution contains silicate.SELECTED DRAWING: Figure 1
【課題】高湿度かつコンクリートが湿っているような環境においても十分な付着強度を発現可能な補修材料を提供すること。【解決手段】補修材料１０は、コンクリート構造物の補修に用いられる補修材料であって、硬化性組成物と、改質剤水溶液と、緻密化剤水溶液と、透液性の補修用基材４と、を備える。硬化性組成物は、珪酸ナトリウムを含む水溶液と、ポゾラン活性物質とを含む。改質剤水溶液は、２価以上の陽イオンと硝酸イオン及び／又は亜硝酸イオンとを含む。緻密化剤水溶液は、珪酸塩を含む。【選択図】図１
