电化学注入阻锈剂对混凝土中Cl^-腐蚀钢筋的阻锈效果

Effect of Electrochemical Injection of Corrosion Inhibitor into Rebar Deteriorated by Chlorides in Concrete

对已用NaCl溶液室内加速活化的钢筋混凝土进行电化学注入阻锈剂、等电量脱盐等处理,通过测定1a内钢筋腐蚀电位、锈蚀速率以及失重率的变化,对比各项钢筋阻锈技术的阻锈效果.结果表明:电化学注入阻锈剂能更有效地防止钢筋的进一步腐蚀.

In connection with the reinforcement concrete accelerated deterioration by chlorides,a series of treatments including electrochemical injection of corrosion inhibitor and salt-extraction etc.were carried on.Then the corrosion potential,corrosion rate and mass loss of rebar were measured for 1 a.The results show that electrochemical injection of corrosion inhibitor can lessen the corrosion more efficiently than the other methods.
