Abstrakt: | A new method providing the existence of the sodalite structure in prepared geopolymers has been studied. From the literature is it known, that geopolymers have analogical structure as natural zeolite - sodalite. The natural mineral ultramarine, that is characteristic for its blue colour, has the sodalite structure as well. An agent was prepared based on the same structure that has ultramarine and natural zeolite - sodalite. In case of existence of the sodalite structures, the agent causes change of the colour of the prepared geopolymers. Prepared geopolymers were studied using XRD a FTIR spectroscopy before and after application of the agent. | ||||||||||
