Historical use of waste from the Jáchymov uranium factory as a building material
Voháňková, Michaela ; Goliáš, Viktor (advisor) ; Šálek, Ondřej (referee)
Between 1853 and 1939, colourful and highly sought-after uranium paints were produced on an industrial scale in Jáchymov. Until the discovery of radium by Marie Curie Skłodowska in 1898, the waste from production was considered essentially worthless. In the 1970s, the use of materials with increased radioactivity was detected in buildings in Jáchymov. Some of the most affected buildings were demolished. In the 1990s, remediation interventions took place during which these building materials (plaster and mortar) were removed from most of the buildings. During this period, gamma radiation doses as well as radioactivity and uranium were measured in the laboratory. The mineralogical and phase character of the material was not investigated, which was the main objective for this bachelor thesis. The presumption of preservation of at least some of the surviving houses was minimal. Nevertheless, a few unique cases have been found. A total of 11 buildings were found along a 12 km tour whose plaster showed elevated radioactivity ranging from 3.2 to 28.4 μGy/h. Sampling was carried out at 6 of them. Determination of 226 Ra mass activities was performed by laboratory gamma spectrometry, uranium contents were determined by instrumental neutron activation analysis. In the study set, the radium activities reached...

Analysis of the effects of material price changes on construction projects
Kopečková, Lucie ; Výskala, Miloslav (referee) ; Hanák, Tomáš (advisor)
The diploma thesis deals with the analysis of the impact of material price changes on construction projects and customer-supplier relations. The theoretical part defines the terms construction company, construction contracts, creation of price offers, budgets and calculations, material costs, describes supplier-customer relations. The practical part analyzes the impact of material price developments on construction projects. In order to answer specific research questions, qualitative and quantitative analyzes were prepared, for which we used our own data, obtained by means of a questionnaire survey, which was subsequently refined through interviews with representatives of construction companies. Furthermore, publicly available data from the ČSÚ and ÚRS were used in the analysis. The practical part discusses the effect of material price changes on construction projects, analyzes their scope and impacts.

Specifics of building design from recycled building materials
Dobrovolný, Petr ; Pifko, Henrich (referee) ; Innemanová,, Petra (referee) ; Žabičková, Ivana (advisor)
Nowadays, the developed societies increasingly adhere to the ideas of sustainability, which also include the issues of raw material intensity and waste management. EU countries declare their intention to move towards so-called circular economy, where production, consumption, waste management and the market of secondary raw materials function in predominantly closed cycles. Due to its high share of raw material consumption and the amount of waste generated, the construction industry is one of the priority sectors in which these changes should take place. Consequently, the interest in recycling of construction and demolition waste will probably grow. This thesis examines the chosen topic from the architect's point of view. The issue of recycling of building materials is dealt with in the context of contemporary construction industry. The introductory part describes main material flows: the most used building materials, the method of waste management and the possibilities of its further use. The relationships between the design of the building and the production of construction waste are defined. The issue of building with recycled building materials is handled in more detail. In the main part, the design of a model object made of recycled building materials is elaborated. The individual building structures are analyzed in terms of the suitability of the use of recycled building materials and waste management after the end of a lifecycle of the building and a comparison is made with alternative structures made of conventional building materials. At the end of the work, an evaluation of the usability of recycled building materials in building structures and their economic potential is performed. There is also an evaluation of the specifics of working with recycled building materials in the design of the building.

Moisture Measurements
Hřib, Jan ; Pikula, Stanislav (referee) ; Beneš, Petr (advisor)
This bachelor’s thesis deals with measuring moisture in building materials and it is focused on the capacitive and microwave method. The goal was to find out whether it is possible to employ these two methods to determine moisture distribution in the volume of a measured material. This thesis contains theoretical introduction to the moisture measurement. Practical experiments were made with both capacitive and microwave method. Capacitive method was supplemented with a simulation. Based on the results, I conclude that the capacitive method is not suitable to determine moisture distribution in the volume of a material. The same conclusion was reached in the case of the microwave method, although this conclusion was based more on the theory than on the measurements.
