This book was released on 2022-10-17 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments aiming at characterizing the effects of moisture content and temperature on the mechanical properties of concrete were conducted. Based on the results of the experiments, theoretical formulations were proposed and a new overall material model capable of predicting the mechanical behaviour of concrete subject to elevated temperatures up to 100 C was developed. The new material model estimates the time, temperature and moisture dependency of the compressive strength, tensile strength, modulus of elasticity, creep and shrinkage of concrete. Consequently, this book provides specific knowledge about the influences of elevated temperatures and moisture content on the mechanical behaviour of concrete as well as a tool to calculate these influences. This shall contribute to the field of investigation of estimating the structural safety under ordinary and extraordinary loadings as well as to the area of evaluating the service life of concrete structures.

Book Synopsis Concrete at High Temperatures by : Zdeněk P. Bažant
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.

This book was released on 2018 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this article, the effect of multiwalled carbon nanotubes on the properties of concrete was evaluated in the postheat-treated condition. For this, a number of cylindrical specimens (10 by 20 cm), including multiwalled carbon nanotubes in different percentages of 0.5, 1, and 1.5 % by weight of cement, were cast. Then, the concrete specimens were exposed to temperatures of 25C, 100C, 250C, 500C, and 700C in an electric furnace, and after they cooled down, compressive and tensile strength tests were carried out on them. The results show that by increasing the number of multiwalled carbon nanotubes in concrete, the compressive and tensile strengths of concrete increase up to 138 and 88 %, respectively. In addition, the dissipation of energy and modulus of elasticity of the concrete specimens were up to two times greater than those of the control specimens. The scanning electron microscope test results indicated that a strong bond between concrete particles exists at room temperature and above.

Book Synopsis Concrete Admixtures Handbook by : V.S. Ramachandran
Download or read book Concrete Admixtures Handbook 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.
Book Synopsis The Effect of Temperature on Creep of Concrete by : H. G. Geymayer
Download or read book The Effect of Temperature on Creep of Concrete written by H. G. Geymayer and published by . This book was released on 1970 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review of the literature on the effect of elevated temperatures on the time-dependent volume change due to load (creep) of concrete reveals incomplete and conflicting evidence. Some workers have found a 'creep maximum' at a particular temperature range; others have not encountered this phenomenon. Among those who have found it, there is lack of agreement as to what the range is. All available data have been collected, reduced to comparable form, and analyzed. The analysis has been reviewed in the light of the several theories of the mechanism of concrete creep. It is concluded that the new results on temperature effects on creep do not resolve the conflicts among the various creep theories, but they tend to support the seepage theory more than any other. Many factors affecting creep are found to be influential at elevated temperatures in analogous fashion to their influence at room temperature. These factors include time under load, applied stress, maturity of concrete, and moisture content of concrete. The effect of temperature, at least up to 50 C, is to increase creep by a factor of two or three at 50 C. (Author).
Book Synopsis Multi-Scale Modeling of Structural Concrete by : Koichi Maekawa
Download or read book Multi-Scale Modeling of Structural Concrete written by Koichi Maekawa and published by CRC Press. This book was released on 2008-11-28 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increases in computer power have now enabled engineers to combine materials science with structural mechanics in the design and the assessment of concrete structures. The techniques developed have become especially useful for the performance assessment of such structures under coupled mechanistic and environmental actions. This allows effective management of infrastructure over a much longer life cycle, thus satisfying the requirements for durability and sustainability. This ground-breaking new book draws on the fields of materials and structural mechanics in an integrated way to address the questions of management and maintenance. It proposes a realistic way of simulating both constituent materials and structural responses under external loading and under ambient conditions. Where the research literature discusses component or element technology related to performance assessment, this book uniquely covers the subject at the level of the whole system including soil foundation, showing engineers how to model changes in concrete structures over time and how to use this for decision making in infrastructure maintenance and asset management.
Book Synopsis Engineered Concrete Mix Design and Test Methods by : Irving Kett
Download or read book Engineered Concrete Mix Design and Test Methods written by Irving Kett and published by CRC Press. This book was released on 1999-11-29 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Romans used an early type of concrete made with natural pozzuolanic cement more than 2,000 years ago. Today, Portland Cement Concrete is the most important material of construction. Yet few books, if any, exist that offer an in-depth analysis of the mixing and testing methods of this vital hydraulic cement. Until now that is. Engineered Concrete: Mix Design and Test Methods helps engineers, as well as laboratory technicians, grasp a better understanding of Portland Cement and Portland Cement Concrete. The book is divided into several sections, with the first, Mix Design Procedures, explaining how concrete batches are designed, mixed, and measured for various consistencies. Another section details the tests of the primary component materials of concrete other than water - namely Portland Cement, aggregates, and mortar - while the final section includes some of the fundamental concrete testing procedures for different strength parameters in conformity with the standards of the American Society for Testing Materials. While focusing solely on Portland Cement, the book also includes information on other hydraulic cementitious materials and additives because of their modern applications. Solidly researched and written, Engineered Concrete: Mix Design and Test Methods provides a clear understanding of mix design and testing of Portland Cement Concrete. As every civil engineer knows, it is the most versatile and important material of construction, and will probably remain so as far into the future as we can see.
