Ash and slag waste (ASW) is a finely dispersed mineral material resulting from the combustion of brown and hard coal at thermal power plants. The involvement of ash and slag waste in industrial circulation is one of the effective ways to solve the issue of energy and resource saving. Utilization of ash and slag waste in industrial production will provide a solution to the environmental problem of environmental pollution by industrial waste - technogenic fine dust and harmful effluents by gradually reducing the rat...

Gypsum-based materials and products currently deserve special attention from specialists in many industries. They are distinguished by high environmental friendliness, manufacturability and safety. The construction industry is showing additional interest in their increased comfort, reduced sound insulation and thermal insulation. Obtaining crystallization structures directly from gypsum dihydrate using a non-hydration hardening scheme competes with many modern technological approaches. In the production of non-fir...

Among the existing methods of processing waste from coal-fired thermal power plants, little attention is paid to the problem of ash disposal with variable composition. During the combustion of coals, various chemical reactions occur as part of their mineral part, resulting in the formation of a new technogenic raw material that differs from natural raw materials in chemical and phase composition and has other technological properties. Using the example of a coal-fired power plant burning coals from six different d...

Improving the performance of the gypsum binder is possible by strengthening the gypsum matrix. The increase in strength is ensured by the introduction of a complex of mineral and chemical additives. The use of waste as components of such a complex solves a set of problems. The market is saturated with competitive and high-quality materials. Designed materials meet modern requirements. In addition, the problems of waste disposal, freeing up space, environmental protection and reducing the resource intensity of prod...
