| Popis: | Among the main promising research areas in materials science and construction industry, where a significant amount of studies is concentrated in the world, it is, primarily, the materials those contain a secondary or low-demand raw materials, industrial wastes. As well as it can be composites synthesized using low-temperature and environmentally friendly technologies. In this study, the influence of high-temperature effects on the structural phase transformations in matrix of granite-based nanostructured binder (NB) was considered. As an analytical tool, confirming this assumption, X-ray phase (XRD) analysis and derivatographic (DTA) analysis, as well as a calculated estimate of the volume of the cells of the crystal lattices of the mineral phases were applied. It was established that thermal exposure in the temperature range from 20 to 900 ºС leads to mineral transformations (α–β transition of quartz) in granite-based NB, but the cell volumes changing of the crystal lattices was not found. Thermal exposure of granite-based NB at 1000 ºС initiates a new crystal phase formation – Leucite K[AlSi2O6], that is structurally identical to zeolite-type mineral such as Analcime Na[AlSi2O6]∙H2O. This phenomenon confirms a structural affinity of between granite-based NB and geopolymer. |
