Book Synopsis Thermal Cracking of Massive Concrete Structures by : Eduardo M.R. Fairbairn
Download or read book Thermal Cracking of Massive Concrete Structures written by Eduardo M.R. Fairbairn and published by Springer. This book was released on 2018-05-23 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a State of the Art Report (STAR) produced by RILEM Technical Committee 254-CMS ‘Thermal Cracking of Mas-sive Concrete Structures’. Several recent developments related to the old problem of understanding/predicting stresses originated from the evolution of the hydration of concrete are at the origin of the creation this technical committee. Having identified a lack in the organization of up-to-date scientific and technological knowledge about cracking induced by hydration heat effects, this STAR aims to provide both practitioners and scientists with a deep integrated overview of consolidated knowledge, together with recent developments on this subject.
Book Synopsis Thermal Cracking in Concrete at Early Ages by : R. Springenschmid
Download or read book Thermal Cracking in Concrete at Early Ages written by R. Springenschmid and published by CRC Press. This book was released on 1994-10-13 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Restraint and intrinsic stresses in concrete at early ages are vitally important for concrete structures which must remain free of water-permeable cracks, such as water-retaining structures, tunnel linings, locks and dams. The development of hydration heat, stiffness and strength, also the degree of restraint and, especially for high-strength concrete, non-thermal effects, are decisive for sensitivity to cracking. Determining thses stresses in the laboratory and in construction components has led to a clearer understanding of how they develop and how to optimize mix design, temperature and curing conditions. New testing equipment has enabled the effects of all the important parameters to be qualified and more reliable models for predictiong restraint stresses to be developed. Thermal Cracking in Conrete at Early Ages contains 56 contributions by leading international specialists presented at the RILEM Symposium held in October 1994 at the Technical University of Munich. It will be valuable for construction and site engineers, concrete technologists and scientists.

Book Synopsis Early Age Thermal Cracking in Concrete Structures by : Nosratollah Tajik
Download or read book Early Age Thermal Cracking in Concrete Structures written by Nosratollah Tajik and published by LAP Lambert Academic Publishing. This book was released on 2011-07 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book has been shown that the early age thermal cracking in concrete structures resulted from either internal restraint caused by differential expansion within concrete member during heating due to larger temperatures gradient between the core, and that the adjacent media or by external restraint to contract on cooling from a temperature peak of the concrete specimen are the critical factors in developing early age thermal cracking. It has been found that the temperature differential that causes early age thermal cracking in concrete is greater than that figure found in previous research. Other factors influencing the development of the thermal cracking were investigated and recommendations on controlling the early age thermal cracking are given. The experimental technique carried out in this research investigation is an improvement on the past research on the early age cracking and the effects of internal and external restraints were studied. Further methods of assessing the risk of the early age thermal cracking in mass concrete under natural environmental conditions developed and the results are compared with those under laboratory conditions.

Book Synopsis Control of Cracking in Reinforced Concrete Structures by : Francis Barre
Download or read book Control of Cracking in Reinforced Concrete Structures written by Francis Barre and published by John Wiley & Sons. This book was released on 2016-08-29 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents new guidelines for the control of cracking in massive reinforced and prestressed concrete structures. Understanding this behavior during construction allows engineers to ensure properties such as durability, reliability, and water- and air-tightness throughout a structure’s lifetime. Based on the findings of the French national CEOS.fr project, the authors extend existing engineering standards and codes to advance the measurement and prediction of cracking patterns. Various behaviors of concrete under load are explored within the chapters of the book. These include cracking of ties, beams and in walls, and the simulation and evaluation of cracking, shrinkage and creep. The authors propose new engineering rules for crack width and space assessment of cracking patterns, and provide recommendations for measurement devices and protocols. Intended as a reference for design and civil engineers working on construction projects, as well as to aid further work in the research community, applied examples are provided at the end of each chapter in the form of expanded measurement methods, calculations and commentary on models.
Book Synopsis Early-Age Thermal Crack Control in Concrete by : T. A. Harrison
Download or read book Early-Age Thermal Crack Control in Concrete written by T. A. Harrison and published by . This book was released on 1992-12 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text brings together knowledge on early-age thermal cracking, which occurs when the restrained thermal contraction strain exceeds the tensile strain capacity of the concrete. It aims to help both the designer and contractor to understand the significance of cracking, the mechanisms and factors influencing early-age thermal cracking, and its methods of control. Thermal expansion, temperature fall from a peak during hydration of the cement and restraint factors are all discussed. The book shows how early-age thermal strains can be reduced by taking appropriate measures during the design and construction of concrete elements, and develops equations for the control of crack width.

This book was released on 2021-05-18 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume gathers the latest advances, innovations and applications in the field of crack control in concrete, as presented by leading international researchers and engineers at the International RILEM Conference on Early-age and Long-term Cracking in RC Structures (CRC 2021), held in Paris, France on April 9, 2021. It covers early-age and long-term imposed deformations in concrete, analytical formulations for calculating crack widths in concrete, numerical simulations of early-age and long-term restrained behaviour of concrete elements, experimental investigations on cracking, on-site monitoring of imposed deformations and cracking, crack control and repair, and sustainability of design and remediation. The conference demonstrated that a comprehensive approach to this problem requires the design of robust experimental techniques, the development of multiscale models and the evaluation of code-based and other analytical approaches relevant to crack control in concrete. The contributions, which were selected through a rigorous international peer-review process, share exciting ideas that will spur novel research directions and foster new multidisciplinary collaborations.
