Concrete Petrography de D. St John

Concrete Petrography

D. St John

I. Sims

In the second part of the book, the chemical, the mineralogical composition and the microfabrics of concretes and related materials are discussed. An illustrated guide to the features that can be observed and identified using a petrological microscope is given. There is an extensive review of the defects, deterioration and failures which can occur in concrete together with the observations and petrographic evidence relating to them. Extensive use has been made of illustrative examples in colour which together with appropriate discussion will assist the engineer as well as both the trainee and experienced petrographer in understanding the nature of the evidence which is basic to petrographic analysis. An extensive glossary of optical and other properties of minerals found in concretes completes this practical handbook.

I believe that this volume will stand for many years as the international standard and definitive source of information on the petrography of concrete and congratulate the authors on their accomplishment*Sydney Diamond, Purdue University, USA in the Foreword**This authoritative book is very welcome arrival...I sincerely congratulate the authors on their tremendous effort to procuce this comprehensive invaluable text on concrete petrography...I would like to strongly recommend it to the whole cross section of professionals, researchers and academics who deal with the examination and evaluation of concrete structures, particularly those suffering from deterioration.*Concrete Institute of Australia**... this is one of those rare 'must read' books... this is a book that unlocks the mysteries of concrete ... one of those books that one feels one must have on the technical bookshelf because you know you will want to refer to it at almost any time... a handsome book ... if you are 'into' concrete in any way, you must try this book ...if only for a new colourful viewof the 'grey old concrete'*The Structural Engineer**... a good reference source...*The Indian Concrete Journal, Sept 1998**.. a comprehensive review ... this book provides a sound description of the literature of the subject ... a valuable resource ... an excellent introduction ... a useful guide to the engineer ... clear and useful photomicrographs ... the value of petrography will be enhanced by this book.*Chemistry and Industry, April 1999
