CONCRETE SEPARATION METHOD FOR REINFORCEMENT CONCRETE STRUCTURE, SURFACE TREATMENT JIG FOR REINFORCEMENT BAR, AND SURFACE TREATMENT AGENT
To provide a concrete separation method for a reinforcement concrete structure capable of making an exposed reinforcement bar to be in a status that electricity can easily pass through it.SOLUTION: A concrete separation method separating concrete from a reinforcement concrete structure by applying power and heat to a reinforcement bar 10 comprises: a deposition step depositing metal M as well as removing an attached matter on a surface 11 of the reinforcement bar 10 by contacting a surface treatment agent 40 including metal salt 41 of the metal M more difficult to be cationized than iron with the surface 11 of the exposed reinforcement bar 10; and a power applying and heating step applying power to the reinforcement bar 10 through the deposited metal M (conductive coating 12).SELECTED DRAWING: Figure 3
【課題】露出させた鉄筋を容易に通電可能な状態にすることができる鉄筋コンクリート構造物のコンクリート剥離方法を提供する。【解決手段】鉄筋10を通電加熱することにより、鉄筋コンクリート構造物からコンクリートを剥離するコンクリート剥離方法であって、鉄と比較して陽イオンになり難い金属Mの金属塩41を含有する表面処理剤40を、露出させた鉄筋10の表面11に接触させて、鉄筋10の表面11の付着物を除去するとともに、金属Mを析出させる析出工程と、析出させた金属M(導電性被膜12)を介して、鉄筋10に通電を行う通電加熱工程と、を含むものである。【選択図】図3
