Corrosion Study On Epoxy Phenolic Interpenetrating Polymer Network System Laminated Reinforcement

Abstract

Corrosion of reinforcement in concrete is highly possible when the structure is situated on/off shore and urban areas due to chloride and carbon ion penetration. When chloride ion penetrates in to the concrete through its pores, the corrosion of reinforcement induced on the surface and the deterioration takes place and the life span of the structure will reduced significantly. The corrosion of reinforcement in  concrete has been prevented by using any one the following common techniques such as lamination on steel and concrete surface,  cathodic cover, corrosion inhibiting admixtures, super plasticizers addition, electrochemical elimination of  chloride and desalination. This study deals with the Epoxy phenolic - IPN system of coating on reinforcement. The properties of coating are analyzed by mechanical, chemical and electrochemical studies. The performance evaluation studies were conducted under aqueous environment. This method was developed to protect structural steels. This kind of lamination is a bodily barrier arrangement that not allows the dampness and chlorides get in touch with the reinforcement surface and the epoxy lamination is an electrochemical corrosion barrier which electrically isolates the reinforcement by sinking the stream of corrosion current.
