REPAIR MEMBER FOR CONCRETE STRUCTURE
To enhance waterproofness of a repair member for a concrete structure, which may secure adhesive strength and maintain repair performance for a long period of time while securing the moisture permeability.SOLUTION: There is provided a repair member for a concrete structure comprising a lamination base and a curable composition containing a silicate aqueous solution, a pozzolanic active substance having an electric conductivity difference of 0.4 mS/cm or more and a water repellent agent. The lamination base is a base material where sheet members of multifilaments assembled in a multiaxial mesh shape and liquid permeable sheet members are laminated. The repair member has a water absorption of 75% or less and a water vapor permeability rate of 20% or more after 24 hours immersion into water.SELECTED DRAWING: Figure 1
【課題】接着強度を確保して、補修性能を長期にわたり維持することができるコンクリート構造物の補修部材の、透湿性を確保しながら防水性を高めることを目的とする。【解決手段】積層基材と、珪酸塩水溶液、電気伝導率差０．４ｍＳ／ｃｍ以上であるポゾラン活性物質及び撥水剤を含む硬化性組成物とを備えたコンクリート構造物の補修部材であって、前記積層基材は、マルチフィラメントを多軸メッシュ状に組み合わせたシート状部材と、透液性のシート状部材とが積層された基材であり、前記補修部材が、水への浸漬２４時間後の吸水率が７５％以下、かつ水蒸気透過率が２０％以上であるコンクリート構造物の補修部材。【選択図】図１
