Abstract:

Corrosion is a natural process, which converts refined metal to a more stable form such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials by chemical and electrochemical reaction with their environment. In order to prevent the corrosion of steel in concrete a number of protection techniques such as coatings to steel, coatings to concrete, cathodic protection, addition of super plasticizers, electrochemical removal of chloride, desalination, electrochemical realkalization and corrosion inhibiting admixtures is identified. Based on literature study rebar coating is found to be effective and economic. An experimental study was conducted to analyze the corrosion resistant property of Coal Tar Epoxy in marine environment. The rebars are subjected to chemical and electrochemical studies such as cathodic disbondment, accelerated corrosion and impressed voltage tests to analysis the effectiveness of coating. The mechanical properties of the coated rebars is analyzed by pull out test. The above test results indicated an appreciable adhesion and corrosion resistant property of Coal Tar Epoxy coating even under aqueous environment of 3.5% NaCl.
