This report provides a comprehensive study on corrosion inhibitors used for steel in concrete, and is one of the few existing studies in the international literature on this specific topic. It covers both the inhibitors used as admixtures in fresh concrete, and the surface-applied inhibitors used as additional protective or repair methods to existing structures.

The report is divided into seven chapters. Chapters 1 and 2 provide an introduction to the use of corrosion inhibitors in concrete. Chapter 3 refers to the experimental results available in the technical literature on inhibitors studied by researchers in the past, and Chapter 4 provides a critical evaluation of the effectiveness of corrosion inhibitors. Chapter 5 includes information on test methods used to evaluate corrosion inhibitors, including useful details while applying each test technique. Chapter 6 focuses on ongoing research work with migrating inhibitors, providing a very interesting and useful overview of current activities and trends in the field. The report concludes with remarks about difficulties in evaluating the effectiveness of inhibitors using available tests and standards.

The inhibitors mentioned are categorized into inorganic and organic, with more emphasis given to the most widely used so far – nitrites and alkanolamines and amines. The mechanism of inhibiting action, long-term efficiency, patents, and field tests and applications are examined in this study. Critical evaluation of the inhibitors is an important element of this report, providing information on the effect of inhibitors on concrete properties and the environment, as well as monitoring the corrosion inhibiting action. The report addresses effectiveness of inhibitors tested both in the laboratory and on field applications. The techniques examined for testing the effectiveness of inhibitors include open circuit potential, polarization resistance, macrocell tests and polarization curves.

The report is very well organized, treating each topic thoroughly, addressing key issues rather than covering all the available literature, and pointing to difficulties and needs for further study. The author has provided an extensive list of carefully selected references covering all important elements mentioned throughout the report. It is worth noting that the main text of 60 pages has 157 associated up-to-date references.

The report covers all essential aspects of corrosion inhibitors for steel in concrete, making it an invaluable reference for both researchers and practitioners. The non-expert in the field will find the text easy to understand with plenty of experimental figures and direction to additional reading material. The corrosion researcher can refer to a valuable summary of laboratory tests and field applications of corrosion inhibitors, and the practitioner will be able to identify important aspects of the use of corrosion inhibitors in concrete. The report reflects the author's and the support group's experience in the topic of corrosion inhibitors, and is definitely an important contribution to the technical literature.
