Chinese Abstract

本文探討鋼筋混凝土之製備條件以及暴露環境對其電化學性質的影響。實驗結果顯示鋼筋混凝土試片在蒸餾水中之電位較在人工海水中者高0.4V;而水泥種類、攪拌掖及養生條件對電位之影響較不顯著。交流阻抗測試結果顯示暴露在人工海水中3個月或5個月之不同試片,其電化學反應機構有明顯的差異。

English Abstract

The effects of sample preparation procedures and exposure environments on the electrochemical behavior of steel in concerete have been investigated. The results showed that the electrochemical potential measured in distilled water was about 0.4 V higher than that in artificial sea water. Whereas, the type of cement used, the mixing water and the curing procedure had no discernible effects on the electrochemical potential measurements both in distilled water and in artificial sea water. Electrochemical impedance spectroscopy (EIS) was employed and the results showed that the electrochemical reaction mechanisms differed appreciably for the specimens immersed in artificial sea water for 3 and 5 months, respectively.
