CEMENT HARDENED MATTER AND REINFORCEMENT CONCRETE STRUCTURE USING THE SAME
PROBLEM TO BE SOLVED: To provide a cement hardened matter using a conductive material in which external equipment is made needless, and the corrosion of the reinforcement is suppressed, and a reinforcement concrete structure using the same.SOLUTION: Provided is a cement hardened matter used for a reinforcement concrete structure or the like, comprising: a conductive material having conductivity; and a metallic material whose ionization tendency is higher than that of iron. In this cement hardened matter, since the metallic material is functioned as a sacrificial anode by a potential difference between the metal and iron included therein, the progression of the corrosion of the reinforcement when being used for a reinforcement concrete structure or the like is suppressed.SELECTED DRAWING: None
【課題】外部設備を不要とし、鉄筋の腐食が抑制される、導電性材料を用いたセメント硬化物及びこれを用いた鉄筋コンクリート構造体の提供。【解決手段】鉄筋コンクリート構造物等に用いられるセメント硬化物において、導電性を有する導電性材料と、イオン化傾向が鉄よりも大きい金属材料とを含有するセメント硬化物。このセメント硬化物は、金属材料が、これに含まれる金属と鉄との電位差により犠牲陽極として機能する結果、鉄筋コンクリート構造物等に用いたときに鉄筋の腐食の進行を抑制する鉄筋コンクリート構造体。【選択図】なし
