Concreting in cold weather requires special knowledge and skills to ensure accelerated hardening and high quality in plain- and reinforced-concrete structures. Cold Weather Concreting familiarizes concrete specialists with the characteristic features of concrete in cold weather, including the effects of frost, methods for hardening in subzero temperatures, and other challenges in cold-weather concreting. Both practical techniques and their underlying theories are covered. The book presents many methods for the thermal treatment of concrete by means of electric current--information previously available only in the Russian literature. It presents unique data in the form of diagrams, drawings, and tables, including a chart of the phase state of concretes of different strengths in the process of freezing at different temperatures, the variation of concrete strains in freezing and thawing, and a diagram of electric fields in concrete when electrodes are placed in front of stirrups.
This book provides a comprehensive and authoritative review of durability of the frost resistance of concrete. It will enable both concrete materials specialists and practising engineers to better understand the deterioration processes which take place during freezing and thawing, and the effects of de-icing salts on concrete. It shows how test pro

This book is a thorough and comprehensive update of the 2002 edition, that incorporates detailed references to the Canadian, American, and British (European) standards, contextualized by the author based on over 30 years of construction experience. In addition to updates to the core text, many new topics are presented in the second edition, including a chapter discussing the methods for achieving quality control and ensuring quality assurance in concrete construction. The book consists of two parts. The first part provides basic information about normal concrete, its grades used on sites and various kinds of modified concretes such as fiber- reinforced concrete, sulphur concrete, roller compacted concrete, high performance concrete, ultra- high performance concrete, and flowing concrete. . It further addresses physical properties of concrete and various types of Portland cement, blended cements, admixtures, additives including properties of aggregates and their influence. The second part of the book highlights the principal causes of concrete deterioration along with protective measures, resulting from incorrect selection of constituent materials, poor construction methods, external factors, chemical attack, corrosion problems, hot and cold weather effects, and the various errors in designing and detailing. Featuring an extensive bibliography of the highly adopted standards as well as manuals and journals critical to the construction industry at the end of each chapter, the volume offers readers an advanced understanding of the theory and practical application of concrete technology and international standards in North America and Britain. Addresses concrete technology as well as concrete construction practices, meeting national and international standards; Maximizes readers' understanding of the principal causes of concrete deterioration along with protective measures; Facilitates readers' grasp of different nomenclature used for the same materials in different parts of the world; Features suitable tables, charts, and diagrams that illustrate and organize useful information; Explains sustainable concrete doctrine and how to achieve it meeting green concrete / building requirements; Provides a glossary, conversion factors, and examples of concrete mix design. ·
Portland Cement Association reference, dealing with fundamentals, cold weather concreting, curing, admixtures, aggregates, mixing, and much more.
Concrete made using mineral cements, the raw materials which on earth are practically endless, is known as one of the oldest building materials and during the last decades of the twentieth century has become a dominant building material for general use. At the same time, the requirements of the quality of concrete and its performance properties, in particular compressive strength, durability, economical efficiency, and low negative impact of its manufacture on the environment have not yet been completely met. Bearing these requirements in mind, researchers and engineers worldwide are working on how to satisfy these requirements. This book has been written by researchers and experts in the field and provides the state of the art on recent progress achieved on the properties of concrete, including concrete in which industrial by-products are utilized. The book is dedicated to graduate students, researchers, and practicing engineers in related fields.
