Development of masonry systeme for simple construction of internal masonry structures
Lidmilová, Klára ; Dobiáš,, Jiří (referee) ; Zach, Jiří (advisor)
The diploma thesis deals with the development of a new masonry system, for the production of which recycled brick could be used as a secondary raw material. In the field of literary research, the work deals with the methods of construction of vertical structures, the possibilities of lightening concrete, the life cycle of building materials and the use of secondary raw materials in construction. In the practical part, a masonry system was designed based on market research in the field of internal non-load-bearing masonry structures and requirements for these structures. In order to achieve these properties, concrete was chosen as the material for its production, where recycled brick was used as an alternative aggregate. As it is supposed to be a system for precise masonry, the material was compacted by vibrocompression. At the beginning, recipes were designed to verify the basic properties of concrete: density of hardened concrete, compressive strength and tensile bending strength, then other properties such as thermal conductivity and sound absorption coefficient were tested on improved recipes. Lightening and dimensional modules have been modified to achieve optimal properties. This was followed by a proposal for the method of masonry and surface treatment of a wall. Finally, the economic and environmental aspects of the masonry system were evaluated.

Possibilities of using recycled materials for the green roofs constructions
Skalková, Markéta ; Žák, Antonín (referee) ; Žižková, Nikol (advisor)
This bachelor thesis deals with the issue of using recycled building materials in the green roofs. It studies the history, function, benefits and negative impacts, composition, division and structural layers of green roofs. The work describes the production, application and common features of recycled building materials. It determines the basic properties of selected recyclates and evaluates their partial suitability as some of the layers of a green roof.

Utilization of recycled brick waste for growing the agricultural plants
Šmírová, Barbora ; Másilko, Jiří (referee) ; Opravil, Tomáš (advisor)
The master thesis follows up on previous bachelor thesis, which dealt with the sorption capacity of brick recyclate. Brick recyclate, as same as brick, excel with very high porosity. For this reason this work deals with possible implementation of plant growth aids (fertilizers) on the inside surface of such highly porous material This thesis studies possibilities of preparation of brick recyclate with the content of components supporting plant growth. It is a material, that is able to bind water in the soil and nourish cultivated plants at the same time. Aim of the work is to find out, what maximum amount of supporting substances, that later will be released back into surrounding enviroment (soil), is possible to incorporate into the brick recyclate. Such prepared recyclate was added in different amounts into predefined substrates, where plants were grown. Subsequently, the growth course, germination and yields of selected crops were monitored. It was verified that the material based on recycled brick enriched with nutrients improves the distribution of nutrients in the soil and positively affects the germination, growth and yields of tested crops.

Enamels containing recycled brick waste
Tmejová, Jana ; Ptáček, Petr (referee) ; Opravil, Tomáš (advisor)
The diploma thesis deals with the possibilities of using recycled brick as a component in the preparation of glazes. Recycled brick is a mixture of crushed bricks, it can also contain a brick tablecloth, its composition and color makes this material practically identical to a brick shard. Due to these properties, it can be assumed that recycled brick can be used to prepare technical glazes with a specific color. The aim of the diploma thesis is to verify the possibilities of using recycled brick for the preparation of technical glazes. For prepared glazes, then evaluate their properties and estimate for which type of product these alternative glazes could be used.

Utilisation of brick recycled materials for water retention in soils
Šmírová, Barbora ; Palovčík, Jakub (referee) ; Opravil, Tomáš (advisor)
This bachelor´s thesis deals with possible utilizations of brick recyclate as an element which cooperates in the field of water retention in the landscape, especially in agricultural soils. Brick recyclate has the same composition and properties as a classic burnt brick, and therefore is very wettable and porous. Above all, these properties are the key element to using brick recyclate as a water holding element in the soil. The aim of this thesis was to determine the ability of brick recyclate to retain water in the soil and then release it back into the soil. Various fractions of brick recyclate were tested experimentally. First experiments were performed with fine quartz sand, and then with two different real samples of soils.. The time for the evaporation of all the added water from the test mixture was assessed. For real samples of soils, experiments continued on the plants under defined laboratory conditions.
