This classic reference has established the value of petrography as a powerful method for the investigation of concrete as a material. It provides an authoritative and well-illustrated review of concrete composition and textures, including the causes of defects, deterioration, and failure that can be identified using a petrological microscope. This new edition is entirely revised and updated and also greatly extended to take account of new scientific developments and significant improvements in instrumentation and to reflect current laboratory working practices, as well as to reflect new understanding of the performance of concrete and related materials.
Now in full color throughout, Concrete Petrography, Second Edition provides case study examples, with appropriate explanatory discussions and practical advice on selecting, handling and preparing specimens. It assists and guides the engineer, the trainee and the experienced petrographer in understanding the scientific evidence that is basic to petrographic analysis and so will lead to more accurate and timely diagnosis and treatment of problems in structural concrete.
This book includes:
Contributions in specialist areas by internationally recognized experts
Explanation of computer techniques as an aid to petrography
Full coverage of inspection, sampling, and specimen preparation
New sections covering recent technological development of equipment
Guidance on observation of cement and concrete mineralogy and microfabrics
Discussion and illustrative examples of deterioration and failure mechanisms
New work and guidance on the determination of water/cement ratio
New color illustrations and micrographs throughout
Thorough updating of standards, other authoritative publications, and references
A fully revised, extended, and updated glossary of optical and other properties
Dr. Alan Poole began his career as a geologist before becoming a consultant specializing in the petrography of aggregates, concrete and related materials. He gained a wide experience of both the practical and research aspects of alkali-aggregate reaction in concrete working both in the UK and abroad. He is involved in specialist post-graduate training, with British and European standards committees and with technical working parties. Dr. Ian Sims is a director of RSK Environment Ltd in the UK, where he is responsible for their Materials Consultancy team (including their Petrography Laboratory) and expert witness services. He is Chairman of the British Standards aggregates committee; and previously Secretary of the Geological Society (Engineering Group) working parties on Aggregates, Stone and Clay materials for construction, also their working party on Hot Deserts: engineering, geology and geomorphology, and of the RILEM international technical committees on alkali-aggregate reactivity in concrete (1988 to 2014).
