| 摘 要： | 某八层大楼一层在装修时发现严重腐蚀。通过对所用钢筋和钢条的化学成分、电动势及形成原电池时腐蚀速度等的测量，综合分析认为，发生腐蚀的主要原因是立柱内打底用的石膏属吸水性材料，形成钢材发生电化学腐蚀的环境条件，加工钢筋和钢条形成了原电池，促进了电化学腐蚀过程。这种原电池化学腐蚀降低了结构或构件的承载能力，在工程实际中必须引起高度重视。

| Abstract: | An eight-floor building was found to have serious corrosion during redecorating. It is shown that the corrosion resulted from electrochemical corrosion formed by reinforcing steel and steel strips in the pillars through measuring the chemical composition, electromotive force and rate of galvanic corrosion. The underlying gesso was bibulous and thus accelerated the electro-chemical corrosion. |

| Keywords: | reinforcing steel electro-chemical corrosion galvanic cell |
