The mourning ceremony Hall Lisen
Chytková, Alžběta ; Marek, Jiří (referee) ; Šindlar, Jiljí (advisor) ; Pěnčík, Jan (advisor)
The aim of this project was to create a dignified place for The last farewell extending current cemetery in Brno Líšeň. The whole design takes in mind a grim situation of the visitors and mostly to right working of layout. The building is placed on the new axis on the northern cemetery border. The long pathway before the hall should bring to mind our journey in the life and big window in the funeral hall refers to infinity after the death. Building itself is made of two volumes. First of them is simple block with affiliated spaces and second one is a ceremony hall itself, which rises towards Marianské údolí. Technical service room is in the basement. The building is aimed to incorporation of the nature and material simplicity.

Modification of the filler in cement-bonded boards with alternative filamentous fillers
Dywor, Michal ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
The cement boards are commonly used as a filler fir or spruce chips-profit wood. The increasing demands for construction materials forcing technology to develop new types of composite materials using an alternative source of fillers. In this work in the context of theoretical knowledge about the specified fibers in composite systems are discussed properties of cement binder and filler for cement – bonded particleboards and alternative materials. The practical part describes the test methods designed recipes and then made boards of which were carved specimens intended for testing the properties of boards with alternative fillers.

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.

Optimisation of cement-bonded particleboard matrix composition by using alternative raw material sources
Roháček, Lukáš ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
The diploma thesis deals with possibility of utilization raw materials from alternative sources for production of cement-bonded particleboards. In theoretical part the possibilities of modifying composition of cement-bonded slabs with emphasis on their matrix are discussed in detail. On basis of the findings and their evaluation, waste from the formatting of cement-bonded particleboards, micronized limestone, heat sink and high temperature fly ash were selected to the composition modification. The mentioned raw materials were analyzed and subsequently tested as substitutes for the matrix of cement-bonded particleboards in the experimental part. The properties of the proposed materials were tested even in the longer term, including the microstructure.

Leisure Time Centre Brno
Kubačka, Jan ; Teplý, Vladimír (referee) ; Odvárka, Antonín (advisor) ; Štěpánek, Ladislav (advisor)
The objective of this project was to design a complex for leisure time activities. This locality, which is slightly declining to the south, is situated in the city of Brno, in the city district of Nový Lískovec, in the current park between Chironova and Plachty streets. After considering the concept, the object – ordinary square – was easily situated in the center of all pedestrian communications. There was created a small square around this point,which is surrounded by four non-rectangular buildings with unique construction system. Whole set of structures seems to be compact from outter park view, so a visitor will identify the complex division only inside. There are four entrances to the central square in the directions of the initial communications. The complex is structured into four functional units. Through sport, gastronomy, cultural hall for up to commercial spaces. Some of the four objects were designed as two-story. Around the whole square there is a gallery, which provides the acces to the services on the second floor. The gallery is connected to the ground by three vertical communications.

Influence of humidity changes to properties of building materials with organic filler
Vasas, Silvestr ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
The bachelor's thesis deals with the issue of dimensional changes of building materials containing organic filler, in connection with changes in the humidity of the environment in which the material is located. Searches of knowledge, especially from the scientific literature showed a significant effect of moisture on volume and weight changes of both wood itself and wood of cement composites. In this respect, the treatment of wood (thermal, chemical, etc.) ort he surface treatment of the final wood of the cement composite (coating systém, impregnation, etc.) is essential to reduce the rate of change due to ambient humidity. Experimental laboratory assessment of dimensional and mass changes proved compliance with theoretical knowledge and extended them by specifying the effect on individual dimensions. The different behavior of cement-bonded particleboards in terms of their hygroskopicity was demonstrated on the changes of the boards surface threatment with the coating system and on the boards without surface threatment.

Boards with alkali activated binder filled with wood chips
Gajdušková, Patricie ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
For the production of cement chipboards, cement is used as a binder which is an ecological burden for our planet. This diploma thesis deals with research into the possibility of replacing it with other alternative materials, especially those that are created as a by-product of other production. The focus is primarily on slag, heating plant slag or brick dust. The theoretical part deals with the previous studies and theoretical knowledge of alkaline-activated matrices which are supplemented with an organic binder such as wood chips which are used to reinforce the boards. The practical part deals with the above-mentioned alternative materials which are tested for the design of recipes for modified boards made of alkali-activated binder reinforced with chips. These modified recipes are subsequently subjected to physical-mechanical tests such as bending strength, modulus of elasticity and other monitored parameters of the boards. Selected board variants were analysed in terms of mineralogical composition and microstructure.
