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.

Brno City Hospital
Seďa, Ondřej ; Hybská, Bohumila (referee) ; Sedláček, Michal (advisor)
The topic of the diploma thesis is the design of a town hospital at Kraví hora in Brno. The design of the new city hospital in Brno replaces the functions of two existing city hospitals, the Merciful Brothers Hospital and the Trauma Hospital, whose technologies do not meet the medical requirements of the 21st century. In the hospital there are standard facilities, namely outpatient medical facilities, including day hospitals, central blood collection, emergency, operating rooms, central sterilization, anesthesiology and resuscitation departments, intensive care units, maternity and neonatology departments, examination complement , laboratories, rehabilitation departments, inpatient departments of surgical and internal medicine, non - medical and commercial premises, personnel background, technical background and parking. The hospital is a 10-storey building. The main idea of the design was to create a hospital with the views of the park even Brno skyline.

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.

Preparation of PP composites by grafting using monomer treated filler
Kramerová, Nina ; Žídek, Jan (referee) ; Kučera, František (advisor)
Bachelor thesis is focused on preparation of composite materials with polypropylene matrix. The composites were prepared “in situ” with using Brabender mixer. Homogenization of matrix and filler and grafting of PP with anhydride of itaconic acid treated filler proceed together according to radical mechanism of polymerization. Luperox 101 [2,5-dimethyl-2,5-di(tertbutyl-peroxy)hexane] was used as an initiator of the reaction, the concentration of the initiator was 0.5 wt %, processing temperature 210 °C, 30 rpm. PP-g-IA is a compatibilizer between the matrix and the filler. Glass fibers, calcite and two types of ground wood pulp were used as filler. Two analytical methods were chosen to analyze the efficiency of grafting, acid-base titration and infrared spectroscopy. Assigned conversion of monomer was from 42 to 87 % for various fillers.

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.
