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.
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.

Download or read book Thermal Stresses and Temperature Control of Mass Concrete written by Zhu Bofang and published by Butterworth-Heinemann. This book was released on 2013-12-11 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods of controlling mass concrete temperatures range from relatively simple to complex and from inexpensive too costly. Depending on a particular situation, it may be advantageous to use one or more methods over others. Based on the author’s 50 years of personal experience in designing mass concrete structures, Thermal Stresses and Temperature Control of Mass Concrete provides a clear and rigorous guide to selecting the right techniques to meet project-specific and financial needs. New techniques such as long time superficial thermal insulation, comprehensive temperature control, and MgO self-expansive concrete are introduced. Methods for calculating the temperature field and thermal stresses in dams, docks, tunnels, and concrete blocks and beams on elastic foundations Thermal stress computations that take into account the influences of all factors and simulate the process of construction Analytical methods for determining thermal and mechanical properties of concrete Formulas for determining water temperature in reservoirs and temperature loading of arched dams New numerical monitoring methods for mass and semi-mature aged concrete

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.

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.
