Abstract
The possibility of processing ash and slag waste formed during the combustion of coal fuel in boiler units of thermal power plants into functional geopolymer materials has been studied. The world experience of processing ash and slag waste into various materials is presented, the potential danger of ash and slag is described. The chemical composition and microstructure of ash and slag of the Apatity CHPP and the Severodvinsk CHPP-1 were studied. Raw materials of geopolymer materials have been developed, their synthesis has been carried out. The physico-mechanical properties of the obtained samples are analyzed - their density and compressive strength are determined. The process of pore formation in the production of geopolymer materials is considered.
