The Study to the Corrosion of Reinforcing Steel in Concrete by Using Galvanostatic Pulse Technique
This paper presents the result from a study of Galvanostatic Pulse Technique for determining the corrosion rate of steel in reinforced concrete. The investigation to the condition factors and instrument parameter that significantly influence the testing result of the current pulse technique in on-site measurements is made in this paper. Firstly standard specimens which have different thickness of concrete cover and NaCl adding content were prepared, and instruments (CorroMap TM) for field measurement of corrosion rate of steel in reinforced concrete are selected for testing. From the study we can conclude that Icorr increased with the decreasing of the thickness of the concrete cover and the adding content of NaCl to the concrete when casting with non-linear rule, and an anodic pulse of 50 μA with pulse duration of 10 seconds is appropriate for testing both passive and active area of rebar.
