Аннотация
На основании анализа литературных источников и собственных исследований определены пределы изменения удельной теплоемкости и теплопроводности бетонов в процессе осуществления их тепловой обработки в теплотехнологических установках. Установлено влияние на величины этих теплофизических показателей температуры, поддерживаемой в процессе тепловой обработки, и достигаемой в результате прогрева степени гидратации. Сделан вывод об определяющем влиянии изменения теплопроводности бетона в процессе его тепловой обработки (по сравнению с удельной теплоемкостью) на результаты аналитических и численных расчетов режимов тепловой обработки.
