In situ corrosion studies were carried out on steel and galvanized steel rods embedded in concrete cylinders. The concrete samples were prepared with different contents of DCI and Rh222 inhibitors in the concrete mix. The corrosion testing was carried out in absence and presence of chlorides in the electrolyte using standard electrochemical methods. The results were compared with the corrosion studies performed on steel substrates and on galvanized steel in model solutions which simulated the rebar-concrete interface. A transient one dimensional mathematical model has been developed and used to predict the corrosion initiation time in a concrete cylinder.

Since the 1970s, research projects and field studies have been conducted on different methods for protecting reinforced concrete bridges from corrosion damage. The methods include alternative reinforcement and slab design, barrier methods, electrochemical methods, and corrosion inhibitors. Each method and its underlying principles are described, performance results of laboratory and/or field trials are reviewed, and systems are evaluated based on the results of the trials. Using performance results from the studies and costs obtained from transportation agencies, an economic analysis is used to estimate the cost of each system over a 75-year economic life using discount rates of 2%, 4% and 6%.

Metals are used at an extremely high rate in the industrial and manufacturing fields. Exemplary properties including strength and ductility have made this material highly dynamic; however, the risk of corrosion remains a vital issue. The study of corrosion prevention has attracted interest from researchers and professionals as new technologies are emerging that can assist in the prevention of material destruction. However, research is lacking on the application of these protective technologies within specific fields. New Challenges and Industrial Applications for Corrosion Prevention and Control provides emerging research exploring the theoretical and practical aspects of protective methods against corrosion and the implementation of these techniques within a wide span of professional disciplines. Featuring coverage on a broad range of topics such as molecular modeling, surface treatments, and biomaterials, this book is ideally designed for engineers, industrial chemists, material scientists, researchers, engineers, academicians, practitioners, and students seeking current research on the technological advancements in corrosion protection in various professional scopes.

Given the widespread use of reinforced concrete in infrastructure, understanding the corrosion of this material is of major importance. As a result there has been a wealth of research into catalysts, inhibitors and effective means of monitoring the rate of corrosion. Corrosion of reinforcement in concrete: mechanisms, monitoring, inhibitors and rehabilitation techniques summarises some of the most significant research and its implications.The book begins by reviewing findings from various experiments designed to test the corrosion rate of metals induced by a range of factors. Later chapters discuss techniques for monitoring and testing for corrosion. The book concludes by assessing important methods of prevention, including corrosion inhibitors, protective coatings and electrochemical methods for protection, together with rehabilitation procedures for susceptible structures.Filled with practical examples and written by a distinguished team of international contributors, Corrosion of reinforcement in concrete: mechanisms, monitoring, inhibitors and rehabilitation techniques is an essential reference for civil engineers using reinforced concrete. Summarises research into catalysts, inhibitors and effective means of monitoring the rate of corrosion Concludes by assessing important methods of prevention

Corrosion of Steel in Concrete: Understanding, Investigation and Repair is a guide for designing, constructing and maintaining reinforced concrete structures, such as buildings and bridges which are subject to reinforcement corrosion. It presents the basics of theory and practice in steel corrosion in concrete and reviews the latest research and developments, such as progress on measuring the corrosion threshold for chloride-induced corrosion. This third edition compares the currently proliferating major national and international standards and guidance documents. New developments are considered, such as hybrid anodes for electrochemical treatment and the latest research and developments in assessment, such as the use of ground penetrating radar to measure the chloride content of the concrete cover. It overhauls coverage of electrochemical repair and rehabilitation techniques and outlines recent innovations in structural repair and construction and investigates their implications for durability. The book is ideal for practitioners and graduate students in structural engineering and concrete technology.
