Cement-bonded particleboards with utilization of alternative raw materials
Urbánek, Libor ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
The diploma thesis is focused on effective utilization of currently produced alternative raw materials in the production of cement-bonded boards. The emphasis is primarily on the scraps and dust arising from the processing of cement-bonded slabs, as well as on slag and limestone. The theoretical part contains a survey of current knowledge about the given issue. In the experimental part, the alternative raw materials were analyzed in detail and their influence (as modifier components of the matrix and the filler) on the properties of cement-bonded slabs was examined. Research and development took place using physico-mechanical, thermal and microstructural methods.

Cultural Center in Koprivnice
Urbánek, Libor ; Pechman, Tomáš (referee) ; Sochor, Jan (advisor)
Architectural conception reflects most problematic issues of the contemporary status. These issues are: too many functions under one roof related to confusing operation, low constructional height and poor backlightening. Thanks to elimination of too many functions and clear definition of new operation the new space has been established inside the building, which is not already used but it is removed from mass of the building. the new solution creates proper backlightening as well as enhances orientation inside of the building. The construction is therefore more open towards its surrounding.

Study of effect of the introduced parameters to aerate of aerated concrete
Urbánek, Libor ; Voves, Jiří (referee) ; Hubáček, Adam (advisor)
Bachelor thesis is focused on aerated concrete, their parameters of composition and properties. Further, the thesis focuses on the study of the effect of the introduced aeration on fresh concrete on its properties in both fresh and hardened state. Emphasis is placed on the assessment of the aeration rate in fresh concrete, as compared to the various parameters of hardened concrete, especially the content of hardened concrete and the durability of concrete. The study is complemented by a description of air pore distribution tests in fresh and hardened concrete, a description of individual aeration additives and a study of the influence of aeration additives on the durability of concrete.

The Students themselves - Student Center Poříčí
Urbánek, Libor ; Müller, Rudolf (referee) ; Makovský, Zdeněk (advisor)
The project addresses the design of student housing for two hundred students, design the canteen with the issuance of 800 lunches per day. The proposal must also provide adequate capacity for underground parking spaces. The building is situated on the corner plot between the streets of Vídeňská and Táborského nábřeží. It is designed as a tri-wing design with an internal atrium, open towards the waterfront. Atrium is meant as the main venue for meeting and communicating accommodated students. The building has two floors underground and seven above-ground floors.

Granery in Slaný
Mívaltová, Markéta ; Urbánek, Libor (referee) ; Mléčka, Jan (advisor)
The aim of the work was not to find a suitable way of new use of the historic building of the baroque granary so as to expand and strengthen the structure of the city's facilities, ideally focused on children and youth. Another area of the solution was the urban connection of the original building with the city's street network. The bachelor's thesis deals with the development of an architectural design for the conversion of a baroque granary. The specific method of intervention was left to the student's choice during the assignment, depending on the chosen strategy. The construction program itself is defined only in a general way and it is possible to extend it with other functions. Although it was possible not to stick to the functions associated with children and youth and to find a completely different use, I finally returned to this topic after the analytical part of the project. Thanks to its location, the solved building becomes an ideal adept for creating a leisure background for the youngest generation. The granary is situated on the edge of the historic center of Slaný, where there are several schools and kindergartens in the immediate vicinity. It is therefore possible to count on the use of space in the design both in the afternoon leisure hours and, for example, during teaching in creative or sports subjects.
