Abstract

Surface-applied corrosion inhibitors are investigated as an efficient method for the repassivation of corroded rebars embedded in mortar specimens, with ladle furnace slag. Prismatic specimens measuring 6 ?x 8 x? 2 cm3, into which 3 steel rebars had been embedded, were analyzed through electrochemical and gravimetric tests. The results show that the corrosion inhibitors are more effective on the reference specimens than on the specimens with LFS and are capable of lowering corrosion rate in specimens with chloride ion percentages of 0.8%, but are not effective on any of the specimens with chloride ion percentages of 1.2% and 2.0% by weight of cement.
