Study of anhydrite binder
Břicháčková, Jana ; Fridrichová,, Marcela (referee) ; Gazdič, Dominik (advisor)
The present work deals with research in the preparation of sulphate anhydrite binders based. It is conceptually divided into a general theory of sulphate anhydrite binders and binders, focusing in particular anhydrite cast floors, as well as search anhydrite binders of research training at the Institute of THD and study requirements for screed materials, with emphasis on anhydrite screed mix.

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.

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.

Methods of Excitation of Sulphate Binder Based on Anhydrite
Adameková, Paulína ; Vavrušková,, Lenka (referee) ; Gazdič, Dominik (advisor)
The presented bachelor thesis is focused on excitation of a sulfate binder based on anhydrite. The thesis is conceptually divided in a theoretical and experimental part. The theoretical part is devoted to the general theory of sulphate binders and anhydrite mortars, at the same time, there is brought view on process of production of historical gypsum binders as well as the current use of anhydrides. In theoretical part of the thesis, there is included study, which is focused on previous research in presented problematics at the THD institution. In the experimental part of the thesis, which is primarily focused on the method of internal excitement, there is elaborated design and mineralogical analysis of input feedstocks as well as the internal waking process itself with subsequent qualitative evaluation using XRD and REM analysis.

Study of Hydration Process of Anhydrite Binders
Verner, Filip ; Vavrušková,, Lenka (referee) ; Gazdič, Dominik (advisor)
The presented work deals with the study of hydration processes anhydrite binders with external exciters. Work is divided into two parts. Conceptually is this work divided into two parts The theoretical part of study contains general theory of gypsum binders, anhydrite binders and research at the institude THD. In the experimental part deals with proposal of recipes, making of samples and subsequent determination of main technological tests and monitoring hydration process by the XRD and DTA analysis.

Study of Hydration of Anhydrite Binders
Duda, Štěpán ; Smetanová,, Lenka (referee) ; Gazdič, Dominik (advisor)
Presented bachelor thesis deals with the study of hydration of anhydrite binders. This thesis is primary focused on testing the various hydration exciters of anhydrite and subsequent monitoring of the hydration process by the XRD analysis and also builts on previous research in this area at the institute of THD. Conceptually is this work divided into two parts. The first part deals with the general theory of sulphate binders. The second part is devoted to the partical testing of the various hydration exciters and their subsequent comparsion.

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.

Car-battery charger
Kadlec, Josef ; Procházka, Petr (referee) ; Červinka, Dalibor (advisor)
This bachelor’s thesis is considered by projection and construction of the car battery charger with switching source. One-pulsed conducting changer is base of this charger. The charger is intended for accumulators of nominate voltage 6 and 12V. Accumulators are charged by method of constant voltage with current limitation of 0.5A, 5A, 20A and 50A. Value 50A has reason during stating of car for example in winter, because the charger helps to battery. The device is equipped with additional protection, which protects the charger and also the accumulator and the supply network. Three pilot lights are the next equipment of the device.
