Effectiveness of Rebar Coatings against Corrosion

Abstract: Corrosion of steel rebar in reinforced concrete constructions, particularly those located in marine environments and industrially polluted areas is one of the major problems. Under such aggressive exposure a suitable method for protection of rebar from corrosion is necessary. Application of suitable protective coating on rebar surface is widely used practical method for this purpose. Such coating is ranged from cement slurry to epoxy. Varity of such coating are available in market leading to the difficulty of selection of appropriate coating depending on its performance. Therefore, the present work aims to study the behavior of different coating used to protect the rebar corrosion and its performance evaluation based on electrochemical measurement. For assessment of progress of corrosion, Half Cell Potential technique is used in the present work. From the experimental work it is observed that epoxy coating is more effective against corrosion
