Download or read book Concrete at High Temperatures written by Zdeněk P. Bažant and published by Prentice Hall. This book was released on 1996 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increased use of concrete in high temperature environments, it is essential for engineers to have a knowledge of the properties and mathematical modelling of concrete in such extreme conditions. Bringing together, for the first time, vast amounts of data previously scattered throughout numerous papers and periodicals, this book provides, in two parts, a comprehensive and systematic review of both the properties and the mathematical modelling of concrete at high temperatures. Part I provides a comprehensive description of the material properties of concrete at high temperatures. Assuming only a basic knowledge of mathematics, the information is presented at an elementary level suitable for graduates of civil engineering or materials science. Part II describes the response of concrete to high temperatures in precise terms based on mathematical modelling of physical processes. Suitable for advanced graduate students, researchers and specialists, it presents detailed mathematical models of phenomena such as heat transfer, moisture diffusion, creep, volume changes, cracking and fracture. Concrete at High Temperatures will prove a valuable reference source to university researchers and graduate students in civil engineering and materials science, engineers in research laboratories, and practising engineers concerned with fire resistance, concrete structures for nuclear reactors and chemical technology vessels.

Download or read book Compressive Strength of Concrete written by Pavel Krivenko and published by BoD – Books on Demand. This book was released on 2020-03-11 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete made using mineral cements, the raw materials which on earth are practically endless, is known as one of the oldest building materials and during the last decades of the twentieth century has become a dominant building material for general use. At the same time, the requirements of the quality of concrete and its performance properties, in particular compressive strength, durability, economical efficiency, and low negative impact of its manufacture on the environment have not yet been completely met. Bearing these requirements in mind, researchers and engineers worldwide are working on how to satisfy these requirements. This book has been written by researchers and experts in the field and provides the state of the art on recent progress achieved on the properties of concrete, including concrete in which industrial by-products are utilized. The book is dedicated to graduate students, researchers, and practicing engineers in related fields.

Download or read book Concrete Admixtures Handbook 2nd Ed written by V.S. Ramachandran and published by William Andrew. This book was released on 1996-12-31 with total page 1183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition ten years ago, significant developments have occurred in the use of admixtures in concrete. Eight new chapters and a full update of the preceding ten chapters bring this book up to date; reflecting the relative advances made in the science and technology of different groups of admixtures. The increased role and development of admixtures in concrete technology is evidenced by a number of conferences, publications, and novel admixtures available in the market place. These developments in the field caused the modification of many chapters in the first edition in order to reflect the advances. Although individual chapters refer to standards and specifications of admixtures, those only interested in the standards or techniques used in investigating admixtures will find the second chapter (Research Technologies, Standards, and Specifications) useful. Admixtures are not as inert as may be presumed. They may chemically interact with the constituents of concrete and affect the properties of the fresh and hardened concrete and its durability. The third chapter deals with these aspects. It was important to devote a chapter to recent attempts in developing new admixtures.
Download or read book Concrete Workability written by Mohamadreza Moini and published by AuthorHouse. This book was released on 2011 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is trying to help expand the knowledge of fresh concrete workability. Concrete workability depends on lots of parameters and varies significantly with conditional alteration. The temperature is of great importance determining the workability. This book presents theoretical information and experimental discussions investigating the influence of fresh concrete temperature and ingredients on the workability. Programming and different statistical programs are applied to include the most appropriate results. Artificial neural network prediction of workability is investigated in two situations; with and without concrete temperature. The most relevant cutting edge studies on this issue are cited and discussed to support the readers for the future studies. Ce livre essaie de faire progresser la connaissance de la fluidité du béton frais. La fluidité du béton dépend de beaucoup de paramètres et varie de manière significative avec le changement des conditions (température, humidité, souffle du vent, lumière du soleil). La température a beaucoup d'importances pour déterminer la fluidité. Ce livre présente des informations théoriques et des discussions expérimentales pour examiner l'influence de la température du béton frais et les ingrédients sur la fluidité. La programmation et les différents programmes statistiques ont été appliqués afin d'obtenir les résultats les plus appropriés. La prédiction de fluidité de RNA (le réseau de neurones artificiels) a été étudié dans deux situations: avec et sans température du béton frais. Les plus pertinentes recherches, concernant ce sujet, ont été faites pour appuyer les lecteurs aux études futures.

Download or read book The Effect of Mixing Water Temperature on Concrete Properties in Hot Weather Conditions written by Mennatallah Amr Assal and published by . This book was released on 2018 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Environmental factors and hot weather conditions can drastically impact the properties, strength and durability of concrete structures. Whereby, higher slump loss rate, faster hydration with accelerated setting, reduced long term compressive strength and plastic shrinkage are more common. Literature review on the impact of hot weather on concrete is not sufficiently elaborated and at the same time majority of studies focused on curing temperature on overall concrete quality, however sufficient research on the effect of casting temperature on the concrete itself and its materials is lacking. This study is carried out to investigate the direct impact of mixing water temperature and concrete temperature on the concrete properties serving in hot weather conditions, with special emphasis to the Egyptian hot climate throughout the year. Thus, the scope of this work is to study mixing water temperature’s impact on concrete properties being a key ingredient to the concrete mix, with direct impact on workability, strength and durability. The feasibility of cooling water as a remedial action in hot climate is covered for various project sizes. To achieve the work objective, four categories of concrete mixtures with various cement contents and admixtures were studied while changing the mixing water temperature at 5, 25 and 45 ̊C to yield a total 12 different test sets. All other concrete ingredients were heated to 45 ̊C ahead of mixing to simulate hot weather conditions. Two sets of results were analyzed starting with fresh concrete tests of slump, unit weight and concrete temperature; in addition to hardened concrete tests of compressive and flexural strengths. Results showed an average 15% increase in the 28 days concrete compressive strength and enhanced workability in 5 ̊C temperature water Vs. 45 ̊C suggesting the strong impact of water temperature on concrete properties and need to add cool mixing water to concrete cast in hot weather conditions. Recommendations are provided towards the incorporation of cold water in concrete with a market feasibility conducted to study the technical and economic aspects resulting in up to 9% reduction in concrete cost with cold mixing water incorporated.
