Preparation and study of Alite
Jančíků, Andrea ; Gazdič, Dominik (referee) ; Dvořák, Karel (advisor)
The bachelor thesis deals with the preparation of the main clinker mineral tricalciumsilicate (Alitu-C3S), mostly theoretically and partially practically. The theoretical part summarizes the main findings of recent years of research of polymorphic phases of this mineral. The practical part is devoted to the preparation of polymorphic phase of M1 alite. The main objective was to prepare the monoclinic phase of M1 and analyze their properties by available analytical methods.

Study of Alit structure and stability
Pernicová, Kateřina ; Všianský,, Dalibor (referee) ; Dvořák, Karel (advisor)
The diploma thesis deals with the laboratory preparation of the main clinker mineral alite. The theoretical part summarizes the main findings of recent research. The practical part is devoted to the preparation and optimization of the methodology for the preparation of alite polymorph. The main goal was to prepare monoclinic phases of M1 and M3 alites and analyze their properties by available analytical methods.

SYNTHESIS AND DETERMINATION OF PROPERTIES OF PURE PHASES OF PORTLAND CLINKER AND THEIR POLYMORPHS
Ravaszová, Simona ; Keppert, Martin (referee) ; Reitermann, Pavel (referee) ; Palou, Martin (referee) ; Dvořák, Karel (advisor)
Quantitative diffraction analysis is currently carried out through Rietveld analysis, which is able to decode the various diffraction lines on a diffraction record, provided that the structural model for each clinker phase is well known. The subject of this dissertation is the laboratory preparation of pure phases of one triclinic and two monoclinic polymorphs of the main clinker mineral alite, which will serve as standards for the calibration of powder X-ray diffraction analysis. The result of this work will be detailed procedures for the preparation of individual polymorphs of alite and calibration relationships for unambiguous and easier identification of monoclinic polymorphs in real clinkers.
