WATER ABSORPTION PREVENTING MATERIAL AND METHOD FOR REPAIRING CONCRETE MEMBER

WATANABE NOBUFUMI

PROBLEM TO BE SOLVED: To provide a water absorption preventing material in which the application amount can conveniently be quantified, and to provide a method for repairing a concrete member using said water absorption preventing material.SOLUTION: Provided is a water absorption preventing material comprising at least one main agent selected from a silane compound and a siloxane compound and a labeled particle containing at least one selected from a magnet and a magnetic material. By detecting the voltage relative value by an overcurrent method the application amount of the water absorption preventing material can be calculated from the correspondence relationship in Figure 3 and a method for repairing a concrete member with a desired amount of water absorption preventing material can be provided.SELECTED DRAWING: Figure 3

【課題】塗布量を簡便に定量できる吸水防止材、及びその吸水防止材を用いたコンクリート部材の補修方法の提供。【解決手段】シラン化合物及びシロキサン化合物から選ばれる少なくとも１つの主剤と、磁石及び磁性体から選ばれる少なくとも１つを含む標識粒子と、を有する吸水防止材。過電流法により電圧相対値を検出し、図３の対応関係から吸水防止材の塗布量を算出することで、所望の吸水防止材塗布量となるようにコンクリート部材を補修する方法。【選択図】図３
