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. This book was released on 1992-12. 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.

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. This book was released on 1994-10-13. 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 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. This book was released on 2016-08-29. 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.
