| 摘 要： | 研究了氨基醇有机阻锈剂对应力加载HRB400钢筋在混凝土模拟孔隙液中锈蚀行为的影响，并采用动电位扫描、电化学阻抗谱(EIS)分析了氨基醇有机阻锈剂抑制应力加载HRB400钢筋锈蚀的作用机制.结果表明：随着加载应力的增大，HRB400钢筋锈蚀加重，但氨基醇有机阻锈剂可以作用于应力加载HRB400钢筋表面，增大其吸附层厚度，抑制混凝土模拟孔隙液中Cl-对HRB400钢筋基体的破坏，具备阻锈效果.

| Abstract: | The effects of alkamine organic inhibitor on the corrosion behavior of stress loaded HRB400 steel in concrete simulated pore solution were studied. The potentiodynamic polarization and electrochemical impedance spectroscopy(EIS) were used to analyze the mechanism of the corrosion inhibition on stress loaded HRB400 steel by amino alcohol organic inhibitor. The results show that with the increase of loading stress, the corrosion of HRB400 steel bars is aggravated, but the alkamine organic inhibitor can act on the surface of stress loaded HRB400 steel bars, increase the thickness of the adsorption layer, and inhibit the chloride in the simulated concrete pore solution to the HRB400 matrix, thus it has the rust proof effect. |
