Corrosion zones of rebar in chloride contaminated concrete through potentiostatic study in concrete powder solution extracts
In this paper an experimental investigation has been carried out to identify semi-immune, active, passive and pitting zones of corrosion of the steel reinforcement in concrete powder solution extracts at different levels of admixed chloride. Potentiostatic linear sweeping test was carried out on thr...

Summary: | In this paper an experimental investigation has been carried out to identify semi-immune, active, passive and pitting zones of corrosion of the steel reinforcement in concrete powder solution extracts at different levels of admixed chloride. Potentiostatic linear sweeping test was carried out on three different types of steel reinforcement in the solution extracts made from concrete with three different types of cement at four levels of admixed chloride content with three
w/
c ratios for two test conditions, i.e., with and without deaeration. From the results obtained it was concluded that chloride content is the major factor in defining the zones of corrosion and the same was further confirmed through ANOVA. |
