	Selection of mortars samples for radiocarbon dating Válek, Jan ; Kozlovcev, Petr ; Fialová, Anna ; Kotková, Kristýna ; Frankeová, Dita ; Skružná, Olga ; Maříková-Kubková, Jana ; Tomanová, Pavla ; Herichová, Iva ; Světlík, Ivo ; Pachnerová Brabcová, Kateřina ; Šimek, Pavel Radiocarbon dating of organic residues may not always correctly determine the age of analysed historic mortars. Therefore, it seems advantageous to use of carbon dating of the carbon contained in the structure of the lime mortar, which will provide representative data of the age of the investigated structure. The methodology presents basic instructions and rules for sample selection, processing, and evaluation. The aim of this methodology is the identification of cases where the radiocarbon dating of a binder is appropriate and to define the reasons why some binder systems fail to provide relevant results.

	Report on the results of the chemical and mineralogical analysis of the plaster sample from the object: Opočno Castle Frankeová, Dita ; Bauerová, Pavla ; Slížková, Zuzana An analysis of historical plaster was carried out using thermal analysis and SEM-EDS analysis. The binders and aggregates of mortars and their surface treatments were characterized. The survey results were used for the design of the repair mortars. Detailed record
	Chemical and microstructural analysis of plaster samples from the Mayrau mine, Kladno – Vinařice Slížková, Zuzana ; Frankeová, Dita ; Vondráčková, Michaela ; Bauerová, Pavla ; Náhunková, Pavla An analysis of historical plasters was carried out using thermal analysis and SEM-EDS analysis. The binders and aggregates of mortars and their surface treatments were characterized. The survey results were used for the design of the repair mortars. Detailed record
	Material composition of paving in the Pilgrimage Church of St John of Nepomuk at Zelena Hora Válek, Jan ; Skružná, Olga ; Kozlovcev, Petr ; Viani, Alberto ; Frankeová, Dita ; Shaikh, Nigar The aim of the study was to verify the material composition of the paving and to evaluate the possible production of replicas. The sampled material was analyzed by using optical microscopy, X-ray diffraction, X-ray fluorescence and thermal analyses. The results showed that the studied paving is of ceramic origin and its composition corresponds to burnt brick clays of local raw materials. Plný tet: PDF Detailed record
	Microscopic analysis of materials sampled from the Mánes bridge in Prague Frankeová, Dita ; Bauerová, Pavla ; Slížková, Zuzana A microscopic analysis of historical concrete samples was performed within the construction-technical survey framework using a scanning electron microscope and SEM-EDS analysis. Characterization of mortar components, concrete degradation degree determination, and chemical corrosion products identification. The results of the survey work were used as a basis for the reconstruction project. Detailed record
	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. Detailed record
	Chemical and mineralogical analysis of a mortar sampled from the well in the yard of the object Sedláčkova 15, Pilsen. Frankeová, Dita ; Bauerová, Pavla ; Slížková, Zuzana The mortar sample was analyzed using a TGA and SEM-EDS analysis as part of the construction and technical survey. The mortars' aggregate and binder components were analyzed, and the binder was identified as a mixture of soil and lime. Detailed record
	Ceiling plaster in the Church of Master Jan Hus in Česká Lípa. Plaster in the Stauss system Válek, Jan ; Skružná, Olga ; Kozlovcev, Petr ; Slížková, Zuzana ; Frankeová, Dita ; Kotková, Kristýna ; Viani, Alberto The studied ceiling plasters were sampled the Mistr Jan Hus Church in Česká Lípa. The material consisted of several layers of paint. The aim of this research was to characterize the individual layers of plaster in the Stauss system. Detailed record
	Chemical and microstructural characterization of the artificial stone sample from the sandstone arcade at the Moravský Krumlov Castle Frankeová, Dita ; Koudelková, Veronika ; Bauerová, Pavla ; Slížková, Zuzana As part of the construction and technical survey, a microscopic analysis of samples of the artificial stone sample was performed using a scanning electron microscope and SEM ‐ EDS analysis. Characterization of mortars' aggregate and binder components was performed, and the binder was identified as portland cement. Detailed record
