Download or read book Sulfate Resistance of Mortars Made Using Portland Cement and Blends of Portland Cement and Pozzolan Or Slag written by G. Sam Wong and published by . This book was released on 1988 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mortar bars were made from 23 Type I, 9 Type II, 2 Type V, 15 Type IP, 5 Type IS, and blends of Type I with slag and with various pozzolans including one silica fume. The bars were stored in a 5-percent sodium sulfate solution and monitored for changes in length and in resonant frequency. The length changes of the bars indicated tht silica fume and a natural pozzolan showed impressive improvement of the blends over the use of a nonsulfate-resistant cement by itself, while blends made using slag, and other pozzolans in the amounts studied, in some cases showed only slightly improved resistance and in other cases no improvements. Keywords: Blended cements, Fundamental frequency, Length change, Mortar bar, Portland pozzolan, Sulfate resistance. (jes).
Download or read book Food Outlook Biannual Report on Global Food Markets written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-11-09 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food Outlook analyses trends and developments in the markets for cereals, the oilseeds complex, sugar, meat, dairy and fish products. The November edition also offers a detailed analysis of the cassava markets and the protracted decline in international coffee prices. An additional feature article analyses the recent conditions in the global markets for bananas and major tropical fruits, where world trade is foreseen to surge by 18 percent from last year. The outlook for global supplies of agricultural commodities in the 2018/19 marketing season remains broadly in line with earlier expectations. While the weather had some impact on crop prospects, the overall production at global level did not change significantly from the forecasts published in the July issue of Food Outlook. Beyond weather-induced revisions, the latest FAO revisions take into consideration the mounting uncertainties regarding trade policies, as well as the changes in exchange rates and rising energy prices.

This book was released on 2019-09-17 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume gathers contributions from the final workshop of the RILEM TC-251-SRT "Sulfate Resistance Testing" on External Sulfate Attack (TESA 2018), held on May 24-25, 2018 at IETcc-CSIC, Madrid, Spain. One of the Technical Committee’s main events, it addressed various aspects of external sulfate attack in concrete structures and test methods. The workshop promoted technical discussions and debates on ideas on these topics, with a focus on evaluating the resistance of concrete exposed to ESA. It also provided a forum for participants from around the globe to share their experiences and research on concrete structures affected by external sulfate attack and on test methods. The book discusses the latest advances in research related to ESA and new developments in test methods, and features real-world case studies of concrete structures affected by external sulfate attack in various countries. It also presents new studies linking field cases and lab tests, including 12 contributions on 3 main themes: mechanisms of alteration in external sulfate attack; field aspects of external sulfate attack; and testing to evaluate the resistance of concrete to external sulfate attack.

Download or read book Performance of Cement Based Materials in Aggressive Aqueous Environments written by Mark Alexander and published by Springer Science & Business Media. This book was released on 2012-12-18 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete and cement-based materials must operate in increasingly aggressive aqueous environments, which may be either natural or industrial. These materials may suffer degradation in which ion addition and/or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening. Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over long periods. Consequences of material failure are usually severe – adversely affecting the health and well-being of human communities and disturbing ecological balances. There are also large direct costs of maintaining and replacing deteriorated infrastructure and indirect costs from loss of production during maintenance work, which place a great burden on society. The focus of this book is on addressing issues concerning performance of cement-based materials in aggressive aqueous environments , by way of this State-of-the-Art Report. The book represents the work of many well-known and respected authors who contributed chapters or parts of chapters. Four main themes were addressed: I. Nature and kinetics of degradation and deterioration mechanisms of cement-based materials in aggressive aqueous environments, II. Modelling of deterioration in such environments, III. Test methods to assess performance of cement-based materials in such environments, and which can be used to characterise and rate relative performance and inform long term predictions, IV. Engineering implications and consequences of deterioration in aggressive aqueous environments, and engineering approaches to the problem.

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.
