Use of Ash and Slag Waste from Thermal Power Plants as an Active Component of Building Materials

This paper presents the use of ash and slag waste generated from the combustion of coal at thermal power plants as a secondary raw material in various areas of industry. The process of separation of ash and slag is considered into the following components: coal, magnetic concentrate, and aluminum si...
