摘要
本文研究了加速氯离子渗透过水泥石试验中铜电极和不锈钢对试验结果的影响;研究表明:铜电极在试验过程中腐蚀严重,产生大量沉淀物,导致阳极溶液中氯离子浓度和通过试件电流值的测量结果偏小;不锈钢电极在试验过程中表面有轻微点蚀,底部腐蚀较严重,同时也产生沉淀物,致使测量结果偏小,但效果好于铜电极。
The influence of electrode on accelerating chloride ion permeation through hardened cement paste was studied. The results were that the corrosion of copper electrode was obvious, and a lot of deposit was generated, which induced that the test results of chloride concentration and solution pH value were lower than the actual value; the corrosion of stainless steel electrode was corrosive pitting, but the bottom of stainless steel electrode corroded obviously, at the same time the deposit was generated, which induced that the results were lower than the actual value, whereas the effect was better than copper electrode.
