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

Cracking occurs in mass concrete when tensile stresses exceed the tensile strength of the concrete. Most of these stresses are caused by restraint against volume change; others occur because of loading conditions and the configuration of the structure. To estimate future tensile stresses, temperature studies must be made to determine the temperature changes which will occur in a structure from the time concrete is first placed in the structure until the structure is in normal operation. These temperature changes are made a part of the design and construction of the structure. The range or amplitude of mean concrete temperature in a mass concrete structure is of primary interest, but temperature gradients are also investigated. The heat of hydration of the cement, the concrete mix proportions, the diffusivity of the concrete, amplitudes of air and reservoir temperatures, and solar radiation affect the concrete temperatures. Knowing the concrete temperatures and temperature changes to be encountered, the width and length of the construction block is determined, the precooling and/or artificial cooling measures are selected, and construction requirements are determined. Included in the latter are surface treatments, operation of cooling systems, height differentials, and foundation irregularities. (Author).

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 concr

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.

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.
