高じん性セメント複合材料を用いたコンクリート構造物のリハビリテーション手法の開発

Electrochemical corrosion control methods have been applied to concrete structures deteriorated
by steel corrosion in concrete. By means of these methods, corrosion control effect can be expected,
but the improvement of mechanical performances or prevention of dropping of concrete pieces can’t
be gained. From such background, experimental investigation was carried out in order to clarify the
possibility of a new electrochemical rehabilitation method, in which the ductile fiber reinforced
cementitious composite bonding and covering the anode material on the concrete surface was used
for improving the mechanical performances of the deteriorated structures. As the results of this study,
bending strengthening effect was confirmed by the flexural bending test of reinforced concrete
specimens applying the proposed method.
