Chemical and microstructural characterization of building materials sampled from Český dům, Moscow, Russia
Frankeová, Dita; Slížková, Zuzana
2020 - Czech
The study was focused on the identification of the material used for the production of facade elements. Using thermal analysis and electron microscopy, it was found that it is not a mortar with a lime or cement binder, but a ceramic element. Studie byla zaměřena na identifikaci materiálu použitého na výrobu fasádních prvků. Pomocí termické analýzy a elektronové mikroskopie bylo zjištěno, že se nejedná o maltu s vápenným nebo cementovým pojivem, ale o keramický prvek.

Chemical and microstructural characterization of building materials sampled from the house No. 86, Nám. 1. máje, Chomutov
Frankeová, Dita; Slížková, Zuzana; Jurkovská, Lucie
2020 - Czech
As part of the construction and technical survey, a microscopic analysis of samples of historic and modern core plaster and stucco was performed using a scanning electron microscope and SEM ‐ EDS analysis. Characterization of the aggregate and binder components of mortars was performed, comparison of mortars from different construction stages. The results of the survey work were used as a basis for the design of the reconstruction of the building. V rámci stavebně-technického průzkumu byl proveden mikroskopický rozbor vzorků historické a moderní jádrové omítky a štuku s využitím skenovacího elektronového mikroskopu a SEM‐EDS analýzy. Byla provedena charakterizace plniva a složek pojiva malt, porovnání malt z různých stavebních etap. Výsledky průzkumných prací byly použity jako podklad pro návrh rekonstrukce objektu.

2020 - Czech
The study was focused on the identification of the material used for the production of paving in the vicinity of the fountain in Prague 6, Na Brusce Street. Using thermal analysis and electron microscopy, it was found that it is natural limestone. The results of the report were used as a basis for the design of the reconstruction intervention of the object.\n\n \n\n Studie byla zaměřena na identifikaci materiálu použitého na výrobu dlažby v okolí fontány v Praze 6, ulice Na Brusce. Pomocí termické analýzy a elektronové mikroskopie bylo zjištěno, že se jedná o přírodní vápenec. Výsledky zprávy byly použity jako podklad pro návrh rekonstrukce objektu.

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
2020 - Czech
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. SEM-EDS a IEC analýza omítky z interiéru Betlémské kaple v Praze prokázala omítkové souvrství sestávající z dvou vrstev jádrové omítky s odlišnou strukturou, štukové vrstvy a povrchové úpravy (nátěru). Omítka je kontaminovaná dusičnany a chloridy, obsah dusičnanů je velmi vysoký.

Survey of the constructions hidden under the floor of the Church of the Assumption of the Virgin Mary in Jindřichův Hradec
Válek, Jan; Skružná, Olga; Kozlovcev, Petr
2020 - Czech
The aim of the non-destructive survey was to determine the presence of building constructures hidden under the contemporary floor. The measurement was performed in the chancel area where a tomb was assumed. Cílem nedestruktivního průzkumu bylo zjistit přítomnost stavebních konstrukcí skrytých pod soudobou podlahou. Měření bylo provedeno v prostoru kněžiště v místě předpokládané tumby.

Region of interest tomography
Vopálenský, Michal; Kumpová, Ivana
2020 - English
During standard tomographic process, the acquisition of tomographic data (projections) is performed with geometric adjustment of the tomographic assembly ensuring that the projection of the entire width of the examined object fits onto the detector during the full object rotation. Because of the limited width of the detector, this approach has a limited maximum achievable resolution for the given specimen diameter. It is possible to make higher magnification, but then the projections do not fit onto the detector, which causes certain problems during the reconstruction, but allows achieving of higher resolution in the always-visible region of the object (the region of interest). The research was focused on evaluation of ROI tomography approach on the TORATOM tomograph.
