Extension of Elementary School
Kuchařík, David ; Kalánek, Jiří (referee) ; Ostrý, Milan (advisor)
The thesis is focused on the design and elaboration of the project documentation of the extension of the elementary school, which is located in Starý Plzenec. The documentation contains requirements according to valid regulations. The proposal is based on the investor's request, which was published as part of the architectural competition announcement. A new building with 1 underground and 3 floors, forming the Y-shaped ground plan, is located on a slightly sloping terrain. In the building there are cloakrooms, kitchen, dining room, 4 main and 4 professional classrooms and hygienic and technical background. The project proposes a slight modification of the existing building. This proposal solves the barrier-free accessibility of both buildings, except for the attic classroom of the existing building. The project also counts from the second construction phase, the construction of a sports hall on the schools premises, which is still not dealt with. In proposal is a new main entrance to the building from the southern side. The support system is wall-mounted. The perimeter walls are made of monolithic concrete connected to concrete monolithic horizontal bearing structures. The inner bearing walls are made of ceramic blocks. The building is covered with a single-layer flat roof with a vegetation layer. The thermal insulation of the building is solved by a thermal insulation system with a ventilated facade. Fire safety, energy saving and thermal protection are provided.

Creating number concept up to 100
Panovská, Lucie ; Hejný, Milan (advisor) ; Jirotková, Darina (referee)
This diploma thesis deals with third-graders from one of Prague's elementary schools and their understanding of numbers. In addition to the Prodos textbooks, some didactical ideas were taken from the Fraus textbooks, which are aimed at the development of children's understanding mathematics. The experiments were carried out in a classroom and lasted one and a half year. Seven pupils were chosen to take part. The experiments were aimed at gauging their semantic and structural understanding of numbers. The pupils worked individually and were individually interviewed after the experiments. The assumption that pupils use strategies that are not taught in the classroom was confirmed, as well as the fact that the operation of subtraction is much more complicated than addition in mental arithmetic and also in written counting. However, the assumption that the pupils perform better when faced with financial matters as opposed to other situations was not confirmed. It came to light that when creating a verbal task, it is necessary to consider the pupil's understanding of the vocabulary used. Key Words: addition, subtraction, decomposition of number, computation, mathematics, calculative strategies

Studying the possibility of improving the frost resistance of concrete
Šafrata, Pavel ; Ťažký, Tomáš (referee) ; Hela, Rudolf (advisor)
The purpose of this study is to summarize theoretical and practical knowledge of frost resistance of concrete. It suggests, that there are numerous factors affecting the freeze-thaw resistence of concrete. These are especially raw materials, production technology, time and method of curing. The influence of addition, air entrainment and air void structure is complied and evaluated experimentally. The testing method is crucial for the evaluation of durability of concrete. Hence, this thesis includes a research of methods used around the world and practical comparison of some of them. This thesis is valuable because of implementation of the requirement in the standard ČSN EN 206 (2014) for the frost resistence of concrete in exposure classes XF1 and XF3.

The possibility of using admixtures for waterroof concrete
Roháček, Lukáš ; Voves, Jiří (referee) ; Hubáček, Adam (advisor)
Bachelor thesis is mainly focused on additions, that have impact on water impermeability and other properities of fresh and hardened concrete. This issue is also described in short section, which is took from foreign reaserch. Thesis further discusses about the standards and regulations that determine, what properties should have waterproof constructions. Experimental part is showing influence of fly ash, slag and silica fume on conzistency, hydratation heat development, strenght, water impermeability, frost resistance and volume changes of the concrete.

Optimization of the concrete composition with the use of recycled concrete aggregates
Skriňáková, Eva ; Holák, Michal (referee) ; Hela, Rudolf (advisor)
Concrete as a building material is subject to continuous innovation and thanks to advanced technology and quantum of research, its properties are still improved. It is logical that the more concrete we produce, the more waste it arises. The volume of this waste can not be stored in landfills endlessly, nowadays most of the waste economies in the world are trying to recycle concrete rubble. The recycling is not such a problem, the technology has been long verified but the quality of the recycled concrete aggregate is unquestionably one of the primary assumption which leads to accomplish required properties of concrete. In fact, the recycling process is „crushing“ the concrete into particles with an effort to eliminate the cement paste on the surface of the aggregate. An ideal solution would be create a resistant and firm coating that would adhere perfectly to the cement matrix. This diploma thesis is focused on the properties of recycled concrete aggregate and methods of improvement and optimization of the concrete mix composition.

Change in the durability of concrete made of recycled concrete by alternative addition of ceramic admixtures
Stavař, Tomáš ; Hoffmann, Oldřich (referee) ; Stehlík, Michal (advisor)
The master thesis dealing with problematic about durability of concrete, with use of recycled concrete and addition of silica additions. Predominant for resistance of concrete constructions is surface layer, through which aggressive gasses and liquids penetrate from surrounding environment. The most important indicator of concrete durability is ability of surface layer transmissions of aggressive substants. In experimental part will be defined the actual state of surface layer by normal testing methods. The transmissions of surface layer will be tested on concrete cubes. Tests for transmissions of air (method TORRENT), of water (method ISAT), of acid gases (dept of carbonation by quick test in 98% CO2) will be carried out and also strength tests. Assessment of positive or negative influence of additions and amount of cement on durability and mechanical properties of concrete will be discussed in conclusion.

Possibilities of using recycled concrete as fine aggregate replacement in cement screeds
Nováková, Iveta ; Brožovský,, jiří (referee) ; Hubáček, Adam (advisor)
The bachelor thesis deals with summary of knowledge about cement-based screed with partial replacement of natural aggregates by recycled aggregates. Special emphasis is given to describing and studying characteristics of cement-based flowscreed. In this study are described feedstocks with requirements which they must meet and test methods for testing properties of screeds. One part is also given to practical application of cement-based flowscreed with partial replacement of natural aggregates by recycled aggregates.

Word problems on basic arithmetics
MALÁ, Barbora
This bachelor thesis with the title Word tasks in arithmetic bases deals with the curriculum of the fifth and sixth grade of the primary schools. The main emphasis is put on the right exercise assignment which is achieved with the demonstration of the fact how small assignment modification can have influence on the solving of particular exercise. The thesis is divided according to particular thematic units and at the same time the exercise are ordered according to the relevant grade. The thesis stylization is composed from the beginning in the way that it can function as a teaching tool individually. There is an addition of many graphic illustration and pictures for better understanding in the thesis.
