tP _*sVj+B v7Jm0【中文摘要】 针对正在逐步推广应用的电化学脱盐技术,本课题在“九五”攻关研究成果的基础上,运用半电池电位法、恒电流脉冲技术和交流阻抗技术等电化学方法,通过对比试验,研究了电化学脱盐处理试件的电化学特征,结果表明电化学脱盐后钢样电位正移,同时RC值升高,交流阻抗图谱发生变化说明钢筋-砂浆的界面区域发生了变化。 X—射线光电子能谱技术测试结果表明电化学脱盐后已活化腐蚀的钢样恢复钝化是可能的,再钝化膜的形成过程是一个不断完善的动态过程,且该过程与电位的正移、RC值的提高具有一致性,从而为工程应用电化学方法判断电化学脱盐效果提供了技术参考依据。电化学脱盐后再钝化膜的组织结构与未发生腐蚀破坏前钢样钝化膜的组织结构相类同。 通过扫描电镜技术进一步研究,电化学脱盐处理引起钢样-砂浆的界面组成发生了变化,使得脱盐试件钢样-砂浆界面的形貌组成特征有别于空白试件。 采用压汞法研究表明,同空白试件比较,电化学脱盐后不同取样位置的砂浆孔结构不相同:钢样附近的孔隙率增大,远离钢样的砂浆孔隙率降低,但总体而言电化学脱盐对砂浆孔结构具有优化作用。

Y*i AKO w0【英文摘要】 Aimed at the Electrochemical Chloride Extraction (ECE) technique which is becoming widely utilized, electrochemical characteristic of samples ECE-treated was studied on the base of ?5?research by electrochemical methods. Results show that along with corrosion potential becoming positive, RC value of rebar in mortar ECE-treated is also increasing. EIS researches show that the structure of rebar-mortar interface changed after treatment. X-ray photoelectron spectroscopy (XPS) analysis show that it is possible the activated corrosion rebar will repassivate after treatment. The repassivation of the rebar is a process of continuously consummating and agrees well with the positively change of rebar potential and the increase of RC value. The structure and composition of the repassivated film is the same as that of the original one. Scanning Electron Microscopy (SEM) was used to study the composition and morphology of rebar-niortar interface. Results show the composition and morphology of reba...更多r-mortar interface changed after treatment. Comparison of ECE-treated and untreated rebar-mortar interface reveals the significant difference in composition and morphology. Mercury Porosimetry analysis for the samples ECE-treated and untreated were performed, for the ECE-treated samples porosity near rebar increased and that far from rebar decreased, however the porosity of samples ECE-treated was improved generally.  还原水利论文/U eYVg
