Аннотация


Статья посвящена исследованиям влияния добавок цементной пыли (в диапазоне 0…27%) на свойства сильно сжимаемых глинистых грунтов. Определены пластичность, характеристики уплотнения, поведение под нагрузкой и прочностные свойства сильно сжимаемой глины, обработанной цементной пылью (ЦП). Показано, что обработка ЦП меняет пластическую природу глины, делая ее менее сжимаемой и улучшая ее прочность за счет процессов флокуляции, агрегации и образования цементных продуктов. Это также делает глинистый грунт менее чувствительным к изменениям содержания влаги и уменьшает его удельный вес. Результаты исследований дополняются определением оптимального содержания ЦП для повышения прочности глинистого грунта.
