Research in the Field of Anhydrite Binders
Břicháčková, Jana ; Smetanová, Lenka (referee) ; Gazdič, Dominik (advisor)
The presented work deals with research in the field of sulfate binders on the anhydrite base. Conceptually, it is divided into a general theory of sulfate binders and anhydrite mortar compounds, which is describing in detail the using of anhydrite mortar compounds on the poured floor screeds, and then the experimental part, where is made the mineralogical analysis of seven different gypsum resources and subsequent is monitored the effect of two sulfate exciters on the achieved technological properties and hydration process.

Calcium Sulphate Binders and Mortars
Koláček, Tomáš ; Vavrušková,, Lenka (referee) ; Gazdič, Dominik (advisor)
This diploma thesis deals with the study of the binder mortar based on calcium sulphate. The theoretical part deals with the general theory of sulfate binders and anhydrite mortars. Further attention is paid to the standard requirements for these binders and mortars and the evaluation of the existing research at the THD Institute. The experimental part is devoted to research of anhydrite mortar for the production of self-leveling mixtures. The subject of the research was the design of a suitable activating agent, performing technological tests on designed anhydrite pastes and mortars and monitoring hydration.

Binders and Mixtures Based on Calcium Sulfate
Hanáček, Jan ; Smetanová,, Lenka (referee) ; Gazdič, Dominik (advisor)
This Diploma Thesis deals with the research and advancements in the field of sulphate binders, especially the anhydrite binder. The theoretical part of the thesis is dedicated to the fundamentals of sulphate binders and anhydrite binders. Its second part also introduces standard requirements for screed coatings together with technological methods of their application. Practical part of the thesis looks at the research and production of anhydrite binder with special emphasis on self-levelling compounds. Various types of plasticizers were used in these compounds and their effectiveness and final product quality are compared.

Waste material based high-performance sulphate binders
Hájková, Iveta ; Kolář,, Karel (referee) ; Rovnaníková, Pavla (referee) ; Gazdič, Dominik (advisor)
The topic of this dissertation was the preparation of a high-quality sulphate binder based on secondary raw materials. For this purpose, the work was primarily focused on the laboratory preparation of beta gypsum from the selected industrial gypsum, the design of the technological process of production and its verification by pilot tests. In the next step, the thesis dealt with the modification of beta gypsum by a selected set of liquefiers. In addition to commercial dehumidifiers, the possible beta casting of beta gypsum was tested by increasing the zeta potential of the gypsum suspension. At the end, a complete complex of construction products was developed based on laboratory and semi-prepared beta plasters, consisting of gypsum plasters, mastics, gypsum premix and small plaster casts.

Research in the preparation of self-leveling anhydrite screeds
Běťák, Rostislav ; Smetanová,, Lenka (referee) ; Gazdič, Dominik (advisor)
Bachelor´s thesis extends the existing results in the field of research of an anhydrite binder and it is divided into two sections. The theoretical section is focused on general sulphate binders and anhydrite binders. Further it contains the description of the technology of floor screed application, demands of norms and comparison of screeds, which are used nowadays. The experimantal section concrens with the research and the development of an anhydrite binder and mainly the utilization of this binder in the field of cast self-leveling floor screeds. For the preparation of self-leveling mixtures were used two different types of anhydrite and theirs main features were compared.

Anhydrite Binders with Internal Excitation
Kantorová, Kateřina ; Vavrušková,, Lenka (referee) ; Gazdič, Dominik (advisor)
The bachelor thesis deals with the internal excitation of anhydrite mortars and is divided into theoretical and experimental part. The theoretical part deals with the general theory of sulfate binders and products during the dehydration of gypsum. Furthermore, the internal excitation of anhydrite is solved. The practical part follows the previous research of the possibilities of excitation of sulphate binders based on anhydrite, which have taken place so far at the thd institute. From the previous bachelor's thesis, which is followed by this bachelor's thesis, two exciters were selected, which were used to perform the internal excitation of anhydrites. The evaluation was based on XRD analysis.

Study of the internal excitation of anhydrite
Kantorová, Kateřina ; Gazdič, Dominik (referee) ; Dvořák, Karel (advisor)
The presented diploma thesis deals with the possibilities of internal excitation of anhydrite mortars. It is divided into a theoretical part, in which the general distribution of sulfate binders is described, focusing primarily on anhydrite, stimulators, and hydration of anhydrite, and a practical part, which is devoted to research, design of the experiment, dosage of stimulators, firings, and the experiment itself. The practical part describes the current research on anhydrite excitation, which took place at the Institute of technology of building materials and components. The diploma thesis follows on from the previous bachelor's thesis. It continues with two internal drivers, which optimize the fineness of grinding and the degree of firing at the same time.
