Введение. В мировой практике последних десятилетий стало нормой использование отходов теплоэнергетики в строительной отрасли. В основном золошлаки применяют при строительстве автомобильных дорог как материал для отсыпки земляного полотна или в виде укрепленного вяжущим материала, в промышленно-гражданском строительстве как материал для выполнения планировочных работ, при засыпке неудобий и карьеров. Однако потенциал его возможного применения намного шире. Крупнозернистые шлаковые отложения, формирующиеся в зоне шлакового размыва, имеют больший потенциал применения, чем прочие ЗШС, однако менее изучены как отечественными, так и зарубежными исследователями. В статье рассматривается вопрос использования крупнозернистых золошлаковых смесей (ЗШС), образованных на электростанциях с котлами, подразумевающими жидкое шлакоудаление, для сооружения оснований дорожных одежд с позиции её механических свойств.

Материалы и методы

Материалы и методы. В рамках исследования изучены образцы шлакового щебня с Новосибирской ТЭЦ- 2, работающей на угле Кузнецкого угольного бассейна (жидкое шлакоудаление), и Новосибирской ТЭЦ-3, работающей на угле Канско-Ачинского угольного бассейна (жидкое шлакоудаление). Определены потери при дробимости отдельных фракций исследованных материалов в сухом и насыщенном водой состоянии. Проведен анализ графиков разрушения для определения модуля общей деформации шлакового щебня.

Результаты

Результаты. Найдено различие в механической прочности проб материала разного генезиса. Определены значения дробимости исследуемых материалов. Оценены полученные при проведении испытаний графики, на основе которых вычислены характеристики деформируемости этого материала (при разной крупности).

Обсуждение и заключение

Обсуждение и заключение. Определены возможные направления использования изученных материалов при строительстве автомобильных дорог.

Introduction

Introduction. The use of the thermal power station’s (TPS) waste in the construction industry becomes the norm in world practice of recent decades. Basically, the researches use ash and slag in the construction of automobile roads as a material for filling the subgrade or in the form of a cement-bound material in industrial and civil construction as a material for planning work, when filling inconveniences and quarries. However, the potential of the ash and slag’s usage is much wider. Coarse-grained slag deposits that form in the zone of slag erosion have a greater potential for application than other ash and slag mixtures, however, these mixtures have been less studied by both domestic and foreign researchers. The paper discusses the use of the boiler slag formed at power plants with boilers involving liquid slag removal for the construction of road pavement bases with the position of its mechanical properties.

Materials and methods

Materials and methods. The author studied samples of boiler slag from Novosibirsk TPS-2, operating (Kuznetsk coal basin) and Novosibirsk TPS-3 (Kansko-Achinsk coal basin). Moreover, the author determined the crushing losses of individual fractions of the investigated materials in a dry and water-saturated state. The author determined the modulus of deformation of boiler slag.

Results

Results. The researcher found the difference in mechanical strength of the different genesis material. The crushing values of the investigated materials are determined.The author estimated the graphs obtained during testing and calculated the deformability characteristics of the material.

Discussion and conclusions. The author determines possible directions of the studied materials’ usage in the road construction.
