Inorganic thermal insulation material for masonry elements
Sedlačík, Martin ; Švec, Jiří (referee) ; Opravil, Tomáš (advisor)
This master’s thesis deals with preparation of foam glass and explores the possibilies of utilization of this material as an inorganic thermal insulating filler of fired hollow bricks. Foam glass was prepared via powder sintering method from waste packaging glass, using limestone and graphite as foaming agents. After inital analysis of raw materials, the effect of mixture composition and different processing parameters on bulk density, pore size and morphology of foam glass was investigated. Last but not least, different ways of manufacturing thermal insulating bricks, by preparation of foam glass directly in the cavities of fired hollow bricks, were tested.

Study of masonry structure protection in floods areas
Heliová, Magdaléna ; Sedlmajer, Martin (referee) ; Zach, Jiří (advisor)
This work is devoted to possibilities of primary and secondary protection of masonry in sphere of lower construction in flood areas. Content of the work is implementation of literary research, which is concerned with load of brickwork during floods and solving a structure so it doesn’t degrade and even destroy. The work is also dedicated in suggestion of hydrophobic preparation and construction technology, which should ensure water impermeability within floods. Goal of the work is finding the optimal method, which can reduce absorption of mason components.

Study of possibilities of hydrofobization of masonry clay blocks for plinth walls
Jirásková, Iveta ; Horský, Antonín (referee) ; Zach, Jiří (advisor)
The work is focused on the design method of hydrophobic cavity brick fittings for the construction of masonry structures, especially plinth masonry and other external structures subjected to elevated moisture. The scope of work is to undertake a literature review of hydrophobic products and methods for reducing absorption of masonry blocks. The work is also practical verification of the effectiveness of selected hydrofobics the brick fittings. The target is to find the optimal method of reducing the absorption of masonry elements, both in terms of the resulting utility properties and economic viewpoint.

Diagnostics methodology of historical brickwork
Bakešová, Martina ; Cikrle, Petr (referee) ; Anton, Ondřej (advisor)
The aim of my bachelor’s thesis is to carry out historical overview of progress of masonry building elements and structures, including their thorough methodology of diagnostics. The introduction text is considering historical progress of masonry elements in Czech Republic and abroad. As following are described brick manufacturing methods of present and past, which is closely related to the progress of brick dimensions and its visual appearance. On sample specimen can be observed mentioned progress in the visual appearance, mechanical properties and so on. The diagnostics of masonry structures is realised via particular tests described in the thesis. Important tests used for overall evaluation are determining brick dimensions, it is volume density, absorption, compressive strength determined via destructive and non destructive methods. Also flexural tensile strength and compressive strength of the mortar. Output of my thesis is overall evaluation of all parts mentioned above.
