Book Description

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.

Boris Alexandrovich Krylov, born in 1926, is a doctor of engineering, professor, and academician of the Academy of Architectural and Building Sciences of Russia, of the Russian Engineering Academy, and of the International Academy of Informatization. Dr. Krylov is an expert in the field of construction under extreme conditions, including Arctic and permafrost regions and regions with dry, hot climate, and in problems relating to acceleration of concrete hardening rate at precast concrete factories and at building sites. He is the author of more than 300 publications, inventions and patents. Dr. Krylov represented the U.S.S.R. at the Reunion Internationale des laboratoires d’essais et de recherches sur les materiaux et les constructions (RILEM) for many years, heading the Technical Committee on Winter Concreting (39-BH) in this organization. He presently is Deputy Director for Research of the Research Institute of Concrete and Reinforced Concrete in Moscow and a professor at Moscow State University of Construction.
