Development of Self-leveling Screed Based on the Ternary Binder System
Běťák, Rostislav ; Vojtek, Miroslav (referee) ; Gazdič, Dominik (advisor)
The thesis deals with the development of self-leveling cement screed with compensated shrinkage. It is a ternary binder system with the majority of portland cement, that in the beginning of setting and hardening form an expandable folder ettringite. At first there was a background research of volume changes of hydrating cement composites and methods for measuring these changes. Various sort of expansion additives were also introduced, the main emphasis was on concepts of calculated formation of ettringite, which are typical for self-leveling underlayment. Background research included the issues of formation of ettringite, influences on it’s nucleation and it’s stability. The practical development of the screed began by measuring volume changes of different pastes on a ternary composition. Selected formulations suitable for use are verified together with additives to semi-application tests. After the final configuration of the screed mixture, there was a test in real application of an representative area. Individual formulations were tested in terms of long-term stability of ettringite in dry and moist environments.

Family house Rb -3
Růžička, Jiří ; Sibilla, Luboš (referee) ; Vlček, Milan (advisor)
The project is design a house with a small establishment. The project includes the layout and the design of the house. The house has three floors with an attic and one basement floor. It is designed as a stand-alone. The first floor of the establishment of the background and the main entrance to the house. The rest of the house is designed for family living. This part is a utility room, basement and garage in the basement. Living room with household equipment is then in the upper part of the house. The house is run by two separate entrances with wheelchair access to the premises and the entrance to the garage in the basement. The house is designed as a brick building of brick masonry Porotherm in modular size 250 (125) mm with ceramic ceilings MIAKO a cylinder. Roofed by a gabled roof. The house is located on a private plot of 1200 m2 with built up area of 120 m2. The land is gently sloping.

Study of mutual influences of volume changes and internal stresses of flow floor screeds
Mikeš, Vít ; Štenko,, Miroslav (referee) ; Šťastník, Stanislav (advisor)
This thesis deals with the comparison of volumetric and stress variations in different formulations of cast floor self-leveling screeds during maturation. These changes were measured by several methods. Furthermore, the strength parameters of the test materials were compared. The test specimens were cured in metallic and elastic forms. The microstructure of these samples were monitored by scanning electron microscopy. In conclusion, the suitability of the tested methods for the given type of flooring materials was evaluated.

Multifunctional house in Karlovy Vary
Růžička, Jiří ; Vlček, Ing Karel (referee) ; Vlček, Milan (advisor)
The project solves a multifunctional Duma building in a vacant lot, contemplated the construction site is located in Carlsbad, in the street Vyhlíce. This is a protected site spa. Part of the project's layout and structural design of the house. It is a six-storey house with an attic and a basement floor. It is designed as a free-standing in the gap as the final house. The layout is divided into two complete units with their own input. There are spaces for business and residential units for permanent housing. Part of the living area are also room house equipment. Inputs to both parts are wheelchair accessible. The house is not wheelchair The house is designed as a brick building of brick masonry Porotherm the module dimensions of 250 (125) mm with reinforced concrete ceilings. Roofed by a hipped roof. The house is located on a private plot of 519 m2 built-up area of 221 m2. The land is gently sloping. The main orientation of the building to the cardinal's east and west. The south wall is adjacent to the neighboring house.
