混凝土中钢筋宏电池腐蚀电流的研究

Study on Macro Cell Corrosion Current of Steel Bar in Concrete

摘要:

在含氯盐混凝土中用零电阻电流计测定了钢筋宏电池阴、阳极之间的腐蚀电流，结果发现腐蚀电流与混凝土中钢筋的腐蚀程度有一定的相关关系，因此，对钢筋宏电池腐蚀电流的测定能够被用来简便地评价混凝土中钢筋宏电池腐蚀程度．

Abstract:

Corrosion current between anode steel and cathode stainless steel embedded in chloride contaminated concrete were measured by zero ohm ammeter. This study indicates that there is a proportional expression between corrosion current and lost mass by corrosion of the steel. The results above show that corrosion current measured by ampere meter reflects the macro cell corrosion extent of steel bar in concrete.
