REPAIR MATERIAL OF CONCRETE STRUCTURE AND REPAIR METHOD OF CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a repair material of a concrete structure capable of improving reinforcement strength by securing adhesive strength.SOLUTION: The present invention is a repair material used for repairing an existing concrete structure, and is the repair material of the concrete structure composed of a base material of laminating a sheet-like member of at least two layers and a hardening resin composition impregnated into the base material, in which in the sheet-like member in the base material, when set as a first layer and a second layer from the concrete structure side, the first layer is a sheet-like member of combining a multifilament in a multiple spindle mesh shape, and the second layer is a liquid-permeable sheet-like member of 2.0 N or more in tear strength, and viscosity at 25°C of the hardening resin composition is 400-3000 mPa.s.SELECTED DRAWING: Figure 1
【課題】接着強度を確保して、補強強度を向上させることができるコンクリート構造物の補修材料を提供することを目的とする。【解決手段】本発明は、既設の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、少なくとも二層のシート状部材を積層した基材と、該基材へ含浸された硬化性樹脂組成物とからなり、前記基材における前記シート状部材は、前記コンクリート構造物側から第一層及び第二層とした場合、前記第一層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であり、前記第二層は引裂強度２．０Ｎ以上かつ透液性のシート状部材であり、前記硬化性樹脂組成物の２５℃での粘度が４００〜３０００ｍＰａ・ｓであることを特徴とするコンクリート構造物の補修材料。【選択図】図１
