В данной статье рассматриваются технологические особенности зимнего бетонирования. Для прогнозирования времени остывания до набора бетоном критической прочности принимаются во внимание: модуль поверхности, начальная и конечная температура бетона, удельная теплоемкость бетона, температуру наружного воздуха, тип опалубки бетона. Рассмотрены дополнительные расходы на теплоизоляцию бетона с учетом его тепловыделений, теплопроводимость тепла различных опалубок.

This paper assesses the technological features of winter concreting. In order to predict the cooling time to the set of critical strength, the following are taken into consideration: surfacing module, initial and final temperature of concrete, specific heat capacity of concrete, outdoor temperature, type of concrete formwork. The additional costs of thermal insulation of concrete are considered by taking into account its heat release, thermal conductivity of heat of various formwork.
