The article presents the results of assessing impact of ash dumps on the natural environment under conditions of burning coal from the Ekibastuz deposit in Kazakhstan. It is shown that in the area of ash storage facility at Ekibastuz SDPP-2 and in the Almaty region, as a result of activities of three thermal power plants, huge amounts of ash dumps have been accumulated and significantly pollute the environment. Possibilities of obtaining popular building materials from them have been determined. The relevance and significance of this problem is enhanced by fact that manmade waste from thermal power plants is insufficiently processed while current ash waste accumulates and occupies huge areas, which withdraws them from land use. Utilization of ash dumps makes it possible to reduce the anthropogenic load on the environment and ensures the rational use of secondary raw materials. Possibility of obtaining agloporite from the ash of Ekibastuz coal used by the thermal power plant of Almaty is studied. The chemical and granulometric composition of ash and slag is determined. X-ray diffraction and differential thermal analyses are performed. The analysis of chemical composition of Ekibastuz ash describes the composition of the mineral substances of coal. The main components are silicon and aluminum oxides, and a large amount of iron oxide is also present. Knowledge of the chemical composition of ash is necessary to decide on the possibility of using it to obtain building materials. Thus, all studies conducted have shown the possibility of using ash and slag waste as secondary raw materials in order to reduce the anthropogenic load on the environment.DOI

Практическое значение
The practical significance of this research lies in substantiating the possibility of utilizing ash and slag waste from thermal power plants in Kazakhstan as secondary raw materials for the production of construction materials, particularly agloporite. The use of these technogenic wastes can reduce the accumulation of ash dumps, decrease the anthropogenic impact on the environment, and promote the efficient use of secondary resources. The obtained results may be applied in the development of technologies for the comprehensive recycling of ash and slag waste and for expanding the raw material base of the construction industry.Данный документ располагается в коллекциях
