Abstract

In present work, anodic polarization tests are conducted on different steel specimens to find out corrosion zone potentials of various corrosion zones. The tests are done in the concrete powder solution extracts contaminated with the varying levels of admixed chloride and sulfate salts, at varying w/c ratios and cement types. The admixed chloride content is fixed at 3.5% and the sulfate content is used as 0, 2.5 and 5%, by mass of cement. Further the free chloride content along with pH of concrete powder solution extracts are found out.
