Slížková, Zuzana ; Frankeová, Dita ; Bauerová, Pavla ; Náhunková, Pavla ; Mácová, Petra ; Ševčík, Radek ; Vondráčková, Michaela
Determination of the chemical and mineralogical composition of the surface layer of sandstone and the speed of water transport through the surface of the stone (comparison of the properties of the light ocher surface and the black surface of sandstone.
Chemical and microstructural analysis of brick samples from the object of Zákupy castle horse stables
Frankeová, Dita ; Bauerová, Pavla ; Náhunková, Pavla ; Ševčík, Radek ; Mácová, Petra ; Slížková, Zuzana ; Vondráčková, Michaela
As part of the construction-technical survey, historical brick samples were characterized using thermal analysis (TGA), scanning electron microscopy (SEM/EDS), ion chromatography (IC), infrared spectrometry (FTIR) and physical tests. The results of the tests testify to the good production quality of the masonry elements used. Based on the analyzes carried out, it can be assumed that the observed damage to the bricks is caused by high wetting of the masonry in combination with frost cycles, as well as crystallization cycles of water-soluble salts present in the surface layer of some bricks.
Characterization of injection material Ledan TA1 for the needs of the preservation of the architectural fragment located under the 3rd courtyard of Prague Castle
Slížková, Zuzana ; Viani, Alberto ; Frankeová, Dita ; Mácová, Petra ; Ševčík, Radek ; Fabeš, Roman
For the purpose of restoring a Romanesque fragment of marl nearby the Old Royal palace, a material survey of the LEDAN TA1 product was carried out. The study aimed to assess the compatibility of this preservative material with historic marl masonry.
Survey of salinity of masonry under III. courtyard at Prague Castle
Slížková, Zuzana ; Ševčík, Radek ; Viani, Alberto ; Mácová, Petra
Archaeological architectural monuments in the area under III. in the courtyard of Prague Castle were monitored in 2021 in terms of the extent of salt efflorescences and their chemical composition. Salt efflorescence on the marlstone walls of the church of St. Bartholomew contain sodium carbonate and bicarbonate, sodium sulfate and calcium sulfate. Sodium nitrate and potassium nitrate were also present in some samples. The aim of the research is to propose measures to mitigate the effect of salts on the degradation of historic masonry.
Report on the results of SEM-EDS and IEC analysis of plaster sampled from the interior of the Bethlehem Chapel in Prague
Slížková, Zuzana ; Ševčík, Radek ; Frankeová, Dita
SEM-EDS and IEC analysis of the plaster from the interior of the Bethlehem Chapel in Prague proved a plaster layer consisting of two layers of core plaster with a different structure, a finishing layer and a coating. The plaster is contaminated with nitrates and chlorides, the content of nitrates is very high.
Report on survey of salinity of masonry under IIIrd courtyard at Prague Castle
Slížková, Zuzana ; Ševčík, Radek
Results of the salinity survey of marlstone „opuka“ historical masonry and other building constructions under III. courtyard at Prague Castle
Analysis of water soluble salts in bricks (Landštejn)
Ševčík, Radek
The research report presents the results of water extracts analysis of bricks originated form Landštejn castle. The determination of chlorides, nitrates and sulphates was performed using ion chromatography.
Analysis of selected elements using ICP-OES
Ševčík, Radek
The research report summarizes the analysis of acid extracts measurements of copper artefacts. Concentrations of selected metals cations were determined using optical emission spectrometer with inductively coupled plasma.
Survey of mortars of the Romanesque chapel in the tower of Landštejn Castle
Válek, Jan ; Skružná, Olga ; Kozlovcev, Petr ; Frankeová, Dita ; Svoboda, Milan ; Ševčík, Radek ; Kotková, Kristýna
Four samples of floor mortars and two samples of plasters were analysed as a part of the survey in the Romanesque chapel located in the tower at Landštejn Castle. The aim was to characterize used raw materials, determine their ratio, characterize the porosity of mortars and compare mortars sorted to different phases of construction.
Application for operation of measuring devices in power engineering
Ševčík, Radek ; Mlýnek, Petr (referee) ; Krajsa, Ondřej (advisor)
This thesis is focused on application development with ARM processor architecture and Linux operating system. It uses cloud hosting services to build, test and deploy applications with container-based virtualization. The application communicates with smart meters on serial buses. It stores measurements in a database. It provides access to devices and measurements in internet network.
