Laboratory microscopic survey of the stratigraphy of colored coatings on building materials of the Morzinski Palace building in Nerudova st. Prague 1
Slížková, Zuzana ; Náhunková, Pavla ; Bauerová, Pavla ; Vondráčková, Michaela
Stratigraphic analysis of the color coatings on the facade of the Morzín Palace in Prague in order to determine the color of the facade for the future restoration of the building.
Microscopic analysis of the mortars sampled from the Hradenín fortress
Frankeová, Dita ; Bauerová, Pavla ; Vondráčková, Michaela ; Slížková, Zuzana
Two mortar samples and one sample of plaster of the exterior facade from the Gothic fortress Hradenín were examined using an electron microscope. The aim of study was to determine the type of mortar binder and to find out the technological procedure of surface coating application.
Chemical and microstructural analysis of sandstone samples from the cemetery portal at the Gothard in Hořice
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.
Analysis of a 19th century mortar
Bauerová, Pavla ; Frankeová, Dita ; Slížková, Zuzana ; Vondráčková, Michaela
Chemical and mineralogical composition of the binder and the aggregates of the mortar, using SEM-EDS and thermal analysis
Chemical and microstructural analysis of plaster sampled from the castle Sychrov (CR) – Breton tower
Slížková, Zuzana ; Frankeová, Dita ; Bauerová, Pavla ; Náhunková, Pavla
The analysed mortar contains 76.5% by weight quartz sand and 23.5% wt. the lime binder - it is highly hydraulic lime. The aggregate of the mortar is made up mostly of quartz. The hydraulicity of the contained lime binder is evidenced by the presence of belitic clinkers, a strongly inhomogeneous microstructure (typical alternation of dense, Ca-enriched parts and more porous decalcified areas) and the presence of silicate components in varying degrees of reaction. It is suggested that the hydraulic binder used could have been artificially prepared by mixing lime with a hydraulic silicate additive.
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.
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.
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.
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.
