DESALINATION PROCESSING SYSTEM FOR CONCRETE, RE-ALKALIZATION PROCESSING SYSTEM AND SALT CONTENT SENSOR AND PH SENSOR USED THEREFOR
PROBLEM TO BE SOLVED: To provide a desalination processing system for concrete capable of grasping a salt content in concrete quantitatively and in a state of being close to a real time, and determining a finish time point of desalination processing.SOLUTION: A desalination processing system for concrete comprises: voltage application means for applying DC voltage in which an anode 30 is installed on a surface of a concrete structure and a reinforcement or a steel frame is a cathode 20; alkaline solution arrangement means for arranging an alkaline solution in the vicinity of the anode; and desalination processing control means to which a detection signal of a salt content detection electrode wire 60 inserted into a sensor insertion hole is input, for determining whether a salt content of the concrete structure is reduced and the salt content is stabilized to a passive state area of a reinforcement or a steel frame, and continuing electrophoresis of chloride ion to an anode side from the vicinity of the reinforcement or steel frame which serves as a cathode by power supply by the voltage application means and the alkaline solution arrangement means.SELECTED DRAWING: Figure 1
【課題】コンクリート中の塩分量を定量的に且つ実時間に近い状態で把握し、脱塩処理の終了時点を決定できるコンクリートの脱塩処理システムを提供する。【解決手段】コンクリート構造物の表面に設置された陽極３０と鉄筋又は鉄骨を陰極２０として直流電圧を印加する電圧印加手段と、アルカリ性溶液を陽極の近傍に配置するアルカリ性溶液配置手段と、センサ挿入穴に挿入された塩分検出電極ワイヤ６０の検知信号を入力して、コンクリート構造物の塩分が減少して鉄筋又は鉄骨の不動態領域に安定化したか判断し、鉄筋又は鉄骨の不動態領域に安定化するまで、電圧印加手段による給電とアルカリ性溶液配置手段によって陰極となる鉄筋又は鉄骨の近傍から陽極側への塩素イオンの電気泳動を継続する脱塩処理制御手段とを備える。【選択図】図１
