"My last word on concrete" - Adam Neville

Adam Neville's reputation as a world leading expert on concrete technology is unquestioned. In this, his final book on concrete he demonstrates the radical thinking that sets him apart through incisive reflections and forecasts. Standard books on concrete often have an encyclopaedic approach and proceed from science to practice but this book is not standard. The author looks at a problem or an issue, and discusses the underlying scientific and technological aspects, including broader contextual topics. Adam Neville describes this as looking at concrete through the wrong end of the telescope, which contributes to a better understanding of concrete practice and to better concrete in practice.

In chapter 2 the author explains how closely we can determine the water - cement ratio of hardened concrete and chapter 4 considers whether we can verify the age of cracks by measuring carbonation. The author then discusses the confused world of sulfate attack on concrete and minimising alkali-silica reaction in concrete. In chapter 5 the book throws light on aspects of sustainability, which way cracks run and highlights the requirements for residential slabs on grade. Workmanship and design and the relevance of litigation to the structural engineer are addressed in Chapter 6 and the book concludes with future forecasts.

Reviews
The approach of this book: In the authors' words... Of course, much can be written about recent developments in concrete and also a different approach is possible. This is why, in 2003, I published a new book under the title Neville on Concrete. That book deals with several aspects of concrete not covered, or only partially covered, previously. But that is not the main feature of Neville on Concrete. Unlike usual books on concrete, which proceed in an orderly and systematic manner from science to practice, the various sections of Neville on Concrete first look at a problem or an issue, and then discuss the underlying scientific and technological aspects. This is like looking at concrete through the wrong end of the telescope, which gives some new insights. I have followed largely the same approach in the present book, Concrete - Neville's Insights and Issues. For example, Sections 4.1 and 4.2 deal with a relation between the age of cracks in concrete and the observed depth of carbonation, a proposition advanced in an insurance case. To prove, or disprove, that relation, the relevant factors influencing the progress of carbonation are considered in detail. The proposition, which was used in litigation, is found to be erroneous. But what is important for a reader of this book is that the relevant sections in Chapter 4 take him or her through the actual pattern of carbonation and provide a scientific understanding of the phenomena involved in a manner more palatable than would be used in a classical text, which starts with the relevant chemical reactions, their kinetics, and the observed changes in the microstructure of the hydrated cement paste. Another distinguishing feature of this book is that it has been written by a sole author, so that the inconsistencies in terminology and internal contradictions are avoided. The only exceptions are Section 2.1 written jointly with P.-C. Aitcin, and Section 4.4 co-authored by Bob Tobin. I am grateful to them for agreeing to include our joint papers in "my" book. I have referred to litigation. Indeed, several sections of this book have their origin in lawsuits in which I appeared as an expert witness. Now that I no longer undertake court work, I feel free publicly to discuss topics on which I provided expert opinion. Of course, I do not identify individual cases or parties, but the lessons to be learnt are aired. The relevance of litigation to the structural engineer is the subject of Section 6.3. Alas, this is a topic of increasing importance because we live in a progressively more and more litigious society, and it behoves us to know the potential pitfalls. To say that litigation benefits no one would be incorrect because a large number of lawyers make good money out of it. The lawyers, who are advocates and not technical people, need technically competent experts. If, in addition, these experts can present well their expertise, if they can robustly resist occasional onslaught by lawyers for the opposing side because they know what they know and, if they neither vacillate nor exceed their field of competence - in other words, they know what they don't know - such experts can command high honoraria. The experts' contribution to establishing technical facts is essential, but we would all do much better without litigation. A great deal of uncertainty would be removed, money expended on lawyers' fees and experts' fees would be saved, insurance premiums for professional work and for construction in general would be lower. In the end, the cost of constructing a building would be lower, which would of course benefit the owner. This book does not deal with all aspects of concrete - indeed, it is not intended to be an encyclopedia, but rather a selected treatment of topics where I have 'hands-on' experience. For an encyclopedic presentation, I cannot resist advertising Properties of Concrete. Different people, especially in different countries, will find different parts of the book of direct interest. So, there is likely to be widespread appeal. In addition, academics with limited research experience, looking for a new research topic will find here a rich mine of topics that need further study and research. This is so because, to deal with a question posed in litigation, I could proceed only thus far. What is described here is a good starting point, or points, for research. A prime example of this situation is Section 4.3 with the unusual title of The Confused World of Sulfate Attack. Adam Neville
