Available in PDF, EPUB and Kindle. Book excerpt: Microscopical methods for quantitative determination of phase percentage in rocks, bricks, portland cement clinkers, and other composite materials, although time consuming, are among the most reliable techniques available. For particle mounts on glass microscope slides, the line, ribbon, or Fleet methods are used. For thin sections or polished sections, the linear traverse or point-counting methods are recommended. Microscopically determined percentages can obviously include crystalline and amorphous phases, which is more than X-ray diffraction can clearly reveal. Microscopical data can be converted into oxides, giving a chemical analysis. The gathering of microscopical data is facilitated by electronic tallying devices and semiautomatic mechanical stages. Finally, microscopical data, properly gathered, can be treated statistically with high levels of confidence. One should be aware, however, of the limits that each microscopical method entails.
Download or read book Cement Clinker Characterization by Scanning Electron Microscopy written by PE. Stutzman and published by . This book was released on 1991 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scanning electron microscope (SEM) is becoming increasingly recognized as an important instrument for the study of portland cement clinker, cement, and concrete. Images of clinker surface topography are used to study particle size and shape, as well as fracture surface features. Microstructural features such as phase distribution and abundance are obtained by imaging polished surfaces. X-ray microanalysis provides qualitative and quantitative elemental composition and images of element distribution. Computer-based image analysis systems are used to process microscope images to enhance details (such as the separation of individual phases) and image analysis for the measurement of features (such as phase abundance). The linking of the SEM with X-ray microanalysis and image analysis under computer control will provide automated, quantitative, and consistent analysis of portland cement clinker.

Book excerpt: 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

Download or read book Lea s Chemistry of Cement and Concrete written by Peter Hewlett and published by Elsevier. This book was released on 2003-11-12 with total page 1087 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lea's Chemistry of Cement and Concrete deals with the chemical and physical properties of cements and concretes and their relation to the practical problems that arise in manufacture and use. As such it is addressed not only to the chemist and those concerned with the science and technology of silicate materials, but also to those interested in the use of concrete in building and civil engineering construction. Much attention is given to the suitability of materials, to the conditions under which concrete can excel and those where it may deteriorate and to the precautionary or remedial measures that can be adopted. First published in 1935, this is the fourth edition and the first to appear since the death of Sir Frederick Lea, the original author. Over the life of the first three editions, this book has become the authority on its subject. The fourth edition is edited by Professor Peter C. Hewlett, Director of the British Board of Agrement and visiting Industrial Professor in the Department of Civil Engineering at the University of Dundee. Professor Hewlett has brought together a distinguished body of international contributors to produce an edition which is a worthy successor to the previous editions.

Available in PDF, EPUB and Kindle. Book excerpt: A new Standard Reference Material (SRM) for portland cement clinker has been produced for the Office of Standard Reference Materials at the National Institute of Standards and Technology (NIST). The SRM clinkers are intended for use in developing and testing quantitative methods of phase analysis for portland cement and cement clinker. The new SRM is one of three clinkers available from NIST representing the range of textures and compositions of North American clinker production. As the original SRM stock for SRM2687 has been depleted, new material was obtained that retained the fine-grained texture of that SRM. Certification of the phase composition of the clinker is based upon consensus means and uncertainties of two independent analytical methods: scanning electron microscopy with image analysis and X-ray powder diffraction (XRD) analyses. The XRD data were subdivided to provide two separate sample sets and were processed by two different Rietveld refinement codes. These codes differed slightly in the determination of the silicate phases, which have very similar powder diffraction patterns and can be difficult to decompose. Therefore, the input data set for determination of the consensus means, uncertainties and informational values is composed of two distinct XRD data sets and one SEM/image analysis data set. The XRD data are close to that determined by microscopy, but some distinct differences are seen. The disagreements may reflect the difficulty in resolving the fine-sized aluminate and ferrite interstitial phases using the microscope and challenges in decomposing highly overlapped powder diffraction data. The XRD data do display greater precision than replicate measurements by microscopy, likely the result of the specimen homogenization resulting from grinding the clinker to a powder. The certified reference values are consensus values, calcuated by combining the results from both measurement techniques using the DerSimonian-Laird method with the standard un

Book excerpt: Portland cement is one of the most traditional of construction materials. Rising costs of the energy required for its manufacture and the increasing interest in understanding the mechanisms of concrete deterioration, as well as the importance of optimising the use of Portland cement in high quality concrete, have continued to sustain interest in this important material. This second edition of this popular book provides an up-to-date introduction to the raw materials and manufacturing processes of Portland cement. It gives an introductory account of cement composition, manufacture, quality assessment, hydration and the resulting microstructure-physical property relationships, and some mechanisms of the chemical degradation of hardened cement paste. The book is primarily intended for students of materials sciences and graduates in pure science or engineering entering the cement or concrete industries. However anyone requiring a good clear introduction to this material will find this book provides helpful information.

This book was released on 2018-12-17 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 74 of Reviews in Mineralogy and Geochemistry contains a selection of papers on the applied mineralogy of cement and concrete, by far the most popular modern building material by volume, with an annual production exceeding 9 billion cubic meters, and steadily growing. Not even all 'concrete' topics can be covered by a single volume, but an interesting assortment was finally obtained. The seven chapters deal with mineralogy and chemistry of (alumina) clinker production and hydration (Pöllmann), alternative raw clinkering materials to reduce CO2 emission (Justnes), assessment of clinker constituents by optical and electron microscopy (Stutzman), industrial assessment of raw materials, cement and concrete using X-ray methods in different applications (Meier et al.), in situ investigation of clinker and cement hydration based on quantitative crystallographic phase analysis (Aranda et al.), characterization and properties of supplementary cementitious materials (SCMs) to improve cement and concrete properties (Snellings et al.), and deleterious alkali-aggregate reaction (AAR) in concrete (Broekmans).
