Аннотация

В статье обоснована необходимость исследования карбонизации бетона и оценки его максимальной карбонизируемости. Приведено основное уравнение прогнозирования изменения во времени по сечению бетона карбонатной составляющей цементно-песчаной фракции бетона. Предложено выражение для оценки предельной величины карбонизации бетона (ПВК). Проведено исследование и получены соответствующие зависимости ПВК от состава бетона, классов по прочности на сжатие С8/10–С50/60, составов смесей, марок по удобоукладываемости П1…П5 и Ж1…Ж4. Выполнен анализ полученных значений ПВК.
