WINE HOUSE NIKOLSBURG MIKULOV
Valová, Markéta ; Velehradská, Dagmar (referee) ; Dýr, Petr (advisor)
The topic of this diploma thesis was to design a winery house in the open landscape in a traditional wine landscape of Mikulov. The designed building serves as a four stars hotel with apartment rooms, restaurant, wellness, wine shop and a small wine farm with a storage of wine. There are unique views to the Mikulov city, Turold hill and surounding vineyards. The longitudinal axe is oriented on northeast–southwest. Majority of rooms, terraces and both atriums are directed on prospective axes. The object has one basement and three groundfloors. It is (situated) into the sloping terrain and constrasts with the wavy landscape of Mikulov for its racional and linear conception. It is inspired by terracced formations in near suroundings and uses it for its mass as well. It creates a new landscape dominant that remainds the geological formation of limestone situated in the surroundings of the Mikulov city. The regular rhytm of windows on facade refers to the Mikulov´s renaissance. The regular placement of window openings, and their rhythm are inspirated by Mikulov renaissance. Smaller holes, glass surfaces, light color of facade, green roof and shielding elements prevent from overheating the object during the summer. The water element in the courtyard offers pleasant refreshment for the visitors.

Effect of ground limestone addition on properties of cement-slag binder systems
Bílek, Vlastimil ; Másilko, Jiří (referee) ; Opravil, Tomáš (advisor)
This thesis deals with the effect of ground limestone addition on properties of cement-slag binder system. The evolution of compressive and flexural strength of binary and ternary systems (pastes), where 25 % of cement was substituted by one or two admixtures in different ratio, were determined and mutually compared. Granulated blast furnace slag and three different limestones were these admixtures. Two of that limestones were natural and one was prepared by a precipitation. For comparison, mixtures, where ash was added insted of slag, were prepared. The mechanism, by which finely ground limestone participates in hydration process, was studied by conduductometric measurements of systems simulating conditions in fresh pastes, and by TG-DTA method, which was used to determination of added limestone amount which remains in its original form and the amount which participates in the formation of hydration products.

Genesis of new ultra-fine particles of milling stock in the course of the mill exposure.
Kejík, Pavel ; Pekař, Miloslav (referee) ; Svěrák, Tomáš (advisor)
This work deals with the study of limestone and corundum dry milling using attritor-type stirred mill in a batch mode. There were stearin and polyethylene glycol used as surfactants and spherical shaped steel grinding elements used for the experimental part of the work. The main idea was to examine behavior of the selected grinding stock type within a long-term grinding forces exposure in selected conditions of ultrafine dry milling leading up to the submicron area. Characterization of samples was performed by laser granulometry, X-ray powder diffraction analysis, flame atomic absorption spectroscopy, objective color determination and electrokinetic potential measurement. Experimetaly measured data implies that in all cases there was a re-agglomeration of the grinding stock particles occurring, although in different stages of the disintegration process and in mutually various degree. The analysis results denote that a larger erosion of the crystal structures with the associated increase of the amorphous phase in the submicron particle size took place in the grinding stock.

Restoration of limestone in Grygov
Hlušková, Lenka ; Mikeš, Stanislav (referee) ; Guzdek, Adam (advisor) ; Šuhajda, Karel (advisor)
The subject of this bachelor thesis is reconstruction of historical building of the limestone in Grygov. This project is based on the subject AG034 Studio of Architectural Design IV - Restoration of Monuments. The main topic of the studio work was to think about the appropriate use of a building of limestone with the extant circular limekiln and adjacent area of former site of limestone, and to create an architectural study. The thesis include plan to convert building and adjacent land to the cultural-educational facility with camp. Rooms of building is going to be use for various cultural and non-cultural social events. The whole land is going to be recultivated and rearranged for use of citizen. It´s attempt to return to the original values of the building´s appearance. This values were suppress during the years. At the same time It´s preserve essence of its place. The new interventions are solved with respect to native construction. Together them are create harmonic connection between the old historical part and the new timeless part.

LABORARTORY BRNO
Trpělková, Lena ; Šupler, Libor (referee) ; Jura, Pavel (advisor)
The site is located on the corner Milady Horakove and Koliště in the city center at a very busy thoroughfare on the edge of the Brno circuit next to the small park within easy reach fluctuate. The basic volume is divided into two materials, one of which closes the city block and second accentuated corner. Accentuation is achieved vertical, but horizontal in the sense MASS MASS PAUSE MASS ! Based on the analysis of a smaller space gallery on the corner and area LABORARTORY center for the development of art. Art Lab creates the background for smaller mass gallery. Facades are united by noble material limestone. The contrast lies in the different dynamics of the grid buildings.

Study of the influence of additions on the durability of aerated concrete
Halešová, Adéla ; Voves, Jiří (referee) ; Hubáček, Adam (advisor)
The aim of this work is to summarise and consider the possibilities of using admixtures and their influence on the durability of aerated concrete.This bachelor's thesis is based on research findings concerning aerated concrete. Furthermore, it deals with the study of inert and active additions. The experimental part is focused on testing trial samples with the addition of admixtures. It examines what is the rate of the possible chosen physically-mechanical features such as the rate of air density, the durability of surface against the effect of water and chemical defrosting substances and achieving the required strength.

The influence of grinding on the limestone properties
Pavlík, Tomáš ; Bednárek, Jan (referee) ; Šiler, Pavel (advisor)
This bachelor thesis deals with dry limestone grinding in the vibratory mill and ball mill. Three different limestone samples were used for milling. Samples were ground in the mills without the addition of surfactants. Several methods of grinding were performed in the vibratory mill. At first, the same weight of limestone samples was ground for different grinding time without any interruption except for one case of grinding with breaks for cooling off the grinding tablet. Another method was grinding of different weights of the same sample. The last one used the same weight of different samples. In the ball mill, sample of one type of limestone was ground for various milling time. The particle size, shape of particles, phase composition and crystallite size were studied for the ground samples. Sieve analysis, laser diffraction analysis, scanning electron microscopy, powder X-ray diffraction analysis and X-ray fluorescence analysis were used to determine these properties. For each mill, the amount of energy consumed for limestone grinding was calculated.

Cement-bonded particleboards with utilization of alternative raw materials
Urbánek, Libor ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
The diploma thesis is focused on effective utilization of currently produced alternative raw materials in the production of cement-bonded boards. The emphasis is primarily on the scraps and dust arising from the processing of cement-bonded slabs, as well as on slag and limestone. The theoretical part contains a survey of current knowledge about the given issue. In the experimental part, the alternative raw materials were analyzed in detail and their influence (as modifier components of the matrix and the filler) on the properties of cement-bonded slabs was examined. Research and development took place using physico-mechanical, thermal and microstructural methods.
