Materials characterization of mortar samples from the archaeological context of the Basilica of St. Wenceslas in Stará Boleslav.
Válek, Jan ; Kozlovcev, Petr ; Svorová Pawełkowicz, Sylwia ; Kotková, Kristýna
The mortar samples were characterized by optical microscopy and SEM-EDS. The aim of the study was to compare them with each other. All three samples have similar structure and material composition. The raw material for the lime was fine-grained sedimentary limestone with high CaCO3 content. The lime matrix has the character of air lime. In addition to the lime binder, there is also a mud-clay binder. This is separate from the lime binder. The sand grains are surrounded by the lime binder and there is a mud-clay filler in the intermediate space, indicating that this component was added as an admixture to the mortar only during use in construction. The sand used corresponds to the local conditions, both to aeolian sands (loess and loess sediments) dominated by worked quartz clasts and, in part, to sediments of fluvial origin (here mainly lithoclasts transported over a greater distance).

Study of Preparation and Properties of Historic Mortars
Majerová, Jana ; Lang,, Karel (referee) ; Fridrichová, Marcela (advisor)
The diploma thesis is concerned with study of preparation and properties of historic mortars. In theoretical part, there is summarized the historic progress of mortars and their material composition. The experimental part is focused on proposition of mortar mixes. The diploma thesis referring to actual research on Institute of Technology of Building Materials and Components, FCE VUT in Brno. The base mixe of historical mortar came from this research. In experiment, there is the base mixe of historical mortar modified with gypsum. In the first phase of the experimental part the basic technological and aplication properties are assessed. The second phase of the experimental part is focused on the course of hydration of the binder in different environments and subseqeunt determination of the phase composition by X-ray diffraction analysis. The aim of the thesis is to determine the optimal amount of gypsum and to optimize the recipe of historical mortar.

Development of Historical Universal Mortar with Blended Binder
Lišovský, Martin ; Wagner,, Štěpán (referee) ; Fridrichová, Marcela (advisor)
The diploma thesis deals with development and properties of historic mortars, evolves and optimizes recipe of historicizing universal mortar with mixture binder, which have been evolves in previous phase. Binder system is based on lime hydrate and metakaolin and is modified with fast-pacing gypsum. Thesis follow up technological properties of mixtures of historicizing mortars and modifies them for current construction industry. It also follows effect of modification to phase composition of binder system and eventually rise of AFt phases.
