Diploma thesis deals with laboratory preparation of the main clinker mineral - alit. The theoretical part summarizes the existing knowledge and the practical part deals with the methodology of preparation of the alite. The main goal was to prepare and study the monoclinic phases of alite, another goal was to optimize the triclinic alite.

Diploma thesis deals with the methodology of preparation of Alit – the main clinker mineral. The content of this work involves design and optimization of the methodology of preparation of pure Alit polymorphs, analysis of their properties by available analytical methods and evaluation of the change of crystallinity in the process of preparation of these polymorphs by XRD-analysis.
