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.

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.

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.

Circular economics in construction
Tatarin, Tomáš ; Marek, Martin (referee) ; Krejza, Zdeněk (advisor)
The goal of this bachelor thesis Circular Economy in Construction is to map the sources of primary raw materials and the production of recyclates in the context of construction production and to perform a price and geographical analysis. The extension of the principles of circular economy is set in the context of the now widespread linear economy. The bachelor thesis is divided into two parts. The theoretical part deals with the analysis of the circular economy and the possibilities of recycling construction waste. The practical part then analyses the current state of production of minerals key to the construction industry, the current production of construction recyclates, the possibilities of increasing recycling and increasing the applicability of the essence of the circular economy. The paper concludes with a summary of the results of the analysis and possible improvements.
