Study of the Effect of Zirconium Dioxide on the Physical and Mechanical Properties of Foamed Geopolymer Materials for Construction Purposes Based on Coal Combustion Waste at Arctic Thermal Power Plants
摘要
The possibility of obtaining foamed geopolymers—building heat-insulating materials based on coal combustion waste at thermal power plants of Severodvinskaya CHPP-1 and Apatitskaya CHPP was considered. A complex of studies of the considered waste was carried out, its chemical (oxide) composition, X-ray phase composition, and microstructural structure were determined. The mechanisms of pore formation during the synthesis of geopolymers are considered, and the most optimal pore former is chosen. The influence of the addition of zirconium dioxide on the strength characteristics of the samples has been established. The density and porous structure of the obtained geopolymer materials based on coal generation waste are analyzed, and the strength characteristics of the samples are also investigated.
