| Title of the article | The study of the phase-mineral composition of zeolite rocks by the method of X-ray phase analysis |
| Abstract. | Problem statement. Natural zeolite rocks are polymineral material. The mineralogical composition of samples of zeolite rocks of the Egyptian and Yemen fields was studied by X-ray phase analysis to reveal the dependence of their re-technological properties and the effect of zeolite phase and mineral structure on cement systems. The data were obtained on a Bruker D8 ADVANCE brand diffractometer using monochromatic CuK?-radiation in the mode of step scanning in geometry «on reflection». Results. In the course of the experiment, diffraction patterns of the studied materials were obtained, representing diffraction patterns in the coordinates of the intensity of the scattered beam from the scattering angle. The results of the relationship between the phase composition of zeolitic rocks and their water requirements and pozzolanic activity in the composition of hydraulic binders are compared. Conclusions. The significance of the results for the construction industry is that knowing the material composition of zeolite rocks can be adjusted technological and technical indicators of concrete with their use. This fact is confirmed by the experiments. Thus, an equal amount of zeolite in the studied rocks (64 %) changes their re-technological properties, which, as we believe, depend on the type and amount of accompanying minerals. The presence of cristobalite in the Yemeni rock leads to an increase in its water demand (up to 53 %) compared to the zeolite rock from Egypt, as well as to an increase in its pozzolan activity (up to 41 %). The presence of silicate impurities (Muscovite and quartz) in the Deposit of zeolite rock from Egypt leads to a decrease in its water requirement. |
