Abstract: 

The present paper considers the properties and technological characteristics of ternary mixtures of loess, Portland cement and zeolite prepared at high moisture content. The unconfined compressive strength, permeability and sorption of the mixtures are determined after different periods of curing. It is established that the analysed mixtures are more suitable for the construction of isolation barriers of waste repositories in comparison with mixtures containing only loess and cement.

Б. Чакалова, К. Тодоров. Пластичный грунтоцемент для изоляционных барьер. В настоящей статье рассматриваются свойства и технологические характеристики 3-компонентных смесей, состоящих из лесса, портланд-цемента и цеолита, приготовленных при высоком влагосодержании. Предел прочности при одноосном сжатии, коэффициент фильтрации и сорбционная емкость смесей определялись на различные периоды выдерживания образцов. Установлено, что исследуемые смеси являются более подходящими для строительства изоляционных барьеров хранилищ опасных отходов по сравненнию со смесями, содержащими только лесс и портланд-цемента.
