This book report presents the results of an experimental investigation on the effectiveness of Migrating Corrosion Inhibitor (MCI) in reinforced concrete structures. The New bell jar experiment has been developed to determine the corrosion initiation of steel surface within 24 hours. This book will be very beneficial for the students and the research scholars who are working on special concretes, Anti Corrosive Cement, Migrating corrosion Inhibitor, Admixed Concrete etc. This book covers a accelerated corrosion techniques on steel in concretes.
