Development of environmental friendly materials
Peterková, Jitka ; ,, Milan Machatka, (referee) ; Plachý, Jan (referee) ; Šťastník, Stanislav (referee) ; Zach, Jiří (advisor)
Increasing demand for new progressive construction materials requires development of modern environmentally friendly materials with excellent end-use properties and reasonable price. One of the main objectives of material research in building industry is using renewable resources of raw materials of industrial waste for development of new construction materials. Current trend of thermal insulation of building constructions results in development of environmentally friendly insulation materials based on renewable material resources from agriculture and stock farming, which could became alternative for current common use insulation materials in the future. The thesis describes research and development of insulation materials based on natural fibres of agricultural origin; in particular fibres of hemp, flax and jute. Hydrothermal behavior of developed materials is studied including computational simulation of behavior of researched materials after building in the construction.

Economic Evaluation of Investment in the Insulation of a Block of Flats in Bytča
Sobola, Martin ; Kosová, Jaroslava (referee) ; Čech, Josef (advisor)
The aim of the diploma thesis is to evaluate the economic efficiency of the investment in the complete insulation of a reference panel apartment building located in Bytča. The issue of the ETICS external contact system, the energy performance of the building, its thermal protection and the possibilities of financing and evaluation of the economic efficiency of the investment in question are approached in this thesis. The output of the diploma thesis will be an evaluation of the current state of the reference building, with a propper proposal for a thermal insulation. The optimal thermal insulation option and the financial provision of the investment will be selected based on economic efficiency indicators.

Monitoring the Influence of ceramic bond on the properties of insulating refractory materials
Friček, Jakub ; Kovář,, Pavel (referee) ; Nevřivová, Lenka (advisor)
Thermal insulating refractories are an integral part of each thermal unit since they reduce its energy consumption. The current phenomenon of saving in both environmental and financial aspects reflects in searching for such possibilities to produce at lower manufacturing and material costs. One of the possible ways is to valorise waste materials. The theoretical part then deals with the division of refractory materials, classification of thermal insulation refractory materials and manufacturing technologies. The experiment is focused on the production of insulating refractory materials made from plastic dough with a possibility of using sawdust and materials made by pressing mixture moist, with a focus on coal bottom ash. Both of these technologies will be tested for the possibility of modification by using mixed clays and of increasing the strength by using clays with lower sintering temperature.
