Development of concrete with limited volume changes
Martanová, Jana ; Skopal, Ing Karel (referee) ; Hela, Rudolf (advisor)
The bachelor thesis deals with volume changes of concrete. Attention is paid to the shrinkage. They describe the different kinds of volume changes in cement concrete, the reason for their creation and the ways in which they can be eliminated. The practical part is focused on monitoring the volume changes of concrete for 28 days using different amount of plasticing additives.

Optimizing requirements for wood coatings
Bednářová, Ilona ; Petránek, Vít (referee) ; Vaněrek, Jan (advisor)
The work deals with wood coating systems. It is focused on the theoretical division of paints due to different aspects, moreover on testing of wood coating systems. In the practical part of the work, the experimental work regarding the influence of weather conditions onto durability of different wood coatings system was preceded. They were compared two different coatings within the basic tests in different environments.

Survey and evaluation state of timber structures
Zouharová, Kateřina ; Anton, Ondřej (referee) ; Heřmánková, Věra (advisor)
The thesis is focused on the assessment of two wooden roof structures of the building, which is located in Brno on the street Rumiště 8. Parts of the work are also theoretical knowledge of roof structures, building technical survey and diagnostic methods. Rating roof truss was based on a survey of sensory and instrumental methods. In the first step were measured dimensions of roof truss members and were determined roof structures. In the next section was researched damage of elements and his causes. Rehabilitation solution was established for each type of damage to the components resist any attack as long as possible. This report had been prepared for the property owner who plans complete reconstruction.

Possibilities of detection of water content in porous environments using electrical impedance spectrometry method
Fejfarová, Marie ; Bartušek,, Karel (referee) ; Bednárová,, Emilia (referee) ; Pařílková, Jana (advisor)
This doctoral thesis with the title “Possibilities of Detecting the Water Content in a Porous Medium Using the Method of Electrical Impedance Spectrometry introduces electrical impedance spectrometry (EIS) as an indirect electrical method of measurement and a tested apparatus for application in water management practice and in material engineering. A wide range of porous media in the area of water management have been narrowed within the preparation of this dissertation thesis to available samples of chiefly sandy soils and in material engineering to typical building materials, which are still solid burnt brick and timber. Measurement took place in the Laboratory of Water Management Research of the Department of Water Structures and in the Laboratory of the Department of Building Materials and Components at the Faculty of Civil Engineering of Brno University of Technology, in the Laboratory of Soil Mechanics of the company GEOtest, a.s. and in the Laboratory of the foreign university KU Leuven, KHBO in the City of Oostende, Belgium. The experiments performed required not only the production of special constructions of measuring probes and their connection, but also modifications of stations at which measurement was carried out. It is possible to use this doctoral dissertation thesis as a methodological manual of how to apply the measuring apparatus based on the EIS method in monitoring changes in the water content in selected porous media due to hydrodynamic stress imposed on it.

Disposal of Biotic Pests by EMW Radiation
Sobotka, Jindřich ; Klečka,, Tomáš (referee) ; Myslín, Jiří (referee) ; Tomíček,, Oldřich (referee) ; Šuhajda, Karel (advisor)
The possibility of using high-frequency electromagnetic radiation in the construction sector is a common knowledge. Various experiments have been carried out to dry construction materials, or even to destroy biotic pests. However, the majority of these experiments have been executed in laboratory conditions. It means they have been carried out under exact limiting conditions, often very far off those conditions in real building practice. Therefore, this dissertation aims at exploring the possibility of utilizing microwave technology in drying and heating of construction materials, in disposing of biotic pests and sterilizing building materials under real conditions in building practice. The thesis will explain that microwaves are a term given to a part of electromagnetic radiation. Electromagnetic radiation is based on the principle that the radiated energy is absorbed by water molecules present in moist building material. In the mass of the irradiated material, the radiated energy is transformed into thermal energy, where a so-called “motion” of water molecules occurs with the energy then being transformed into kinetic energy. The microwave technology itself offers a very wide range of use, which can be easily achieved, thus making the technology available to use in the future. Part of the experiments and the necessary measurements, too, has been carried out on selected types of building materials in the premises of the Faculty of Civil Engineering of Brno University of Technology. They have been executed under conditions which most closely correspond to the conditions in real buildings. Part of the experiments and the necessary measurements were carried out on particular constructions, by the so-called in situ method. As stated in the conclusion of the dissertation, laboratory measurements and the in situ measurements differ considerably in some cases.

Economy and ecology of biomass utilization
Plíšek, Petr ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This bachelor thesis deals with an economic and environmental contexts of biomass utilization. The first part focuses on the description of the nature and manner of use of biomass. Another part is focused on economic aspects related to biomass. A necessity in the processing a particular energy source is its ecological problems, that is the third chapter. The last part is devoted to the design condensing heat exchanger and its output relative to the fuel wetness content, and boiler output with a condensing exchanger depending on the combustion products cooling temperature.
