Effects of the different grinding technology on the properties of Portland cement
Švéda, Matěj ; Všianský,, Dalibor (referee) ; Dvořák, Karel (advisor)
This diploma thesis compares impact of various high-energy grinding technologies on crystallographic and granulometric properties of portland cement. It also observes the influence of the conventional and high-speed grinding technology on the resulting physical and mechanical properties of portland cement, depending on the storage time.
SYNTHESIS AND DETERMINATION OF PROPERTIES OF PURE PHASES OF PORTLAND CLINKER AND THEIR POLYMORPHS

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.
