The technology of aerated concrete
Koutný, Ondřej ; Repka, Martin (referee) ; Opravil, Tomáš (advisor)
Civil engineering is integral part of industry in each developed country. Naturally the construction point does not play the main role here, but also the material of building segments. In last fifty years the new possibility has been discovered against classic brick in form of autoclaved aerated concrete. This material gathers its customers not only due to low weight and easy application with sufficient strength, but particularly due to excellent heat-insulation properties. Contemporary trend in research of aerated concrete points to application of alternative raws, as for example metakaoline, to improve final properties of product by preserving of current technology and price.
Study of vacuum insulated material properties in civil engineering
Dvořák, Richard ; Vala, Jiří (referee) ; Šťastník, Stanislav (advisor)
Study of vacuum insulated material properties, their advantages and disadvantages of usage in buildings. Elaborating study of technic legislation for insulation in buildings, basic properties of heat transfer, moisture effect and other heat phenomena. Basic principles of vacuum insulated materials, their typical construction and current risks. Their next development and possible extension on market.
The Effect of Microspheres on the Properties of Insulating Chamotte
Majerová, Jana ; Keršner, Štěpán (referee) ; Sokolář, Radomír (advisor)
The bachelor´s thesis is focused on the influence of different kind of microspheres on properties of insulating chamotte. The theoretical part resumes the knowledge about chamotte and microspheres, which are available on domestic market. The practical part is focused on comparing different kinds of microspheres and their influence on chosen properties of insulating chamotte.
Calculation of flue gas properties
Štenclová, Kristýna ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
This Bachelor´s thesis deals with properties of combustion products depending on temperature. The first part is theoretical and includes summary of basic terms of combustion. The second part includes a recherché. It is focused on elementary analysis of fuel and basic properties of combustion products, i.e. heat capacity, density, enthalpy, heat conductivity, kinematic viscosity and number of Prandtl. In the last part of thesis, there is an example of a spe-cific exchanger and his solving based on four various inputs of these properties.

Worst scenario method applied to heat conductivity structures formed by composite materials
Chleboun, Jan
Uncertain conductivity coefficients are considered. They are not given directly bat they stem from an admissible family of composite materials characterized by uncertain concentrations of their constituents. The goal is to maximize a weakly continuous **st functional and to suggest an approximate method suitable for numerical solution of the problem.
