Methylene Blue Test for Plasticity Determination of Brick Clays
Jiroušek, Štěpán ; Stančík,, Hynek (referee) ; Sokolář, Radomír (advisor)
The Bachelor thesis is focused on methods for assesing the plasticity of ceramic raw materials (clays). The theoretical part describes the origin, species, chemical and mineralogical composition of these raw materials. Then we describe the preparations and standardized and nonstandardized methods of assesing the plasticity of clay used in the Czech Republic and abroad. The practical part describes executed tests of brick soils specimen used in the Czech Republic. The outcome of this work is to find correlations between these tests and the determined value of sorption of methylen blue.

Impact of uncoventional technologies of soil cultivation on soil quality
Suchá, Kateřina ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Agricultural land is being handled by various tillage of soil which affects properties of soil. There are two types of tillage treatment. These are conventional (classic) tillage with plowing and minimization tillage (plowing is excluded). The aim of this particular work is to assess the quality of the soil near the village of Bohaté Málkovice, which is being (long-term) handled by minimization tillage. As indicators of soil quality, we used selected physical and physico-chemical characteristics, which are determined from analysis of disturbed and undisturbed soil samples from the top soil layer (0-10 cm) by standard methods in laboratory conditions. The theoretical part describes the basic physical properties of the soil and the ways of their determination. The practical part is devoted to the presentation of the examined locality and the results of selected physical and physico-chemical properties of the soil are presented and subsequently evaluated. In the conclusion, the impact of used tillage in Bohaté Málkovice on the selected soil properties is assessed.

Milling of asphalt layers of pavements
Brida, Peter ; Hýzl, Petr (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis is focused on the comparison of the influence of the milling machine movement speed on the properties of RAP (reclaimed asphalt pavement). The theoretical part describes issue of production and usage of RAP. The practical part evaluates the sieve size distributions of these materials and needle penetration and softening point of bitumen recovered from RAP samples.

Comparement of results from infiltration tests
Blahut, Dominik ; Mazáč, Petr (referee) ; Duchan, David (advisor)
The aim of this thesis is to compare the results of water infiltration from field tests, from laboratories and from numerical modeling at two selected locations. The first objective is the search procedure and the description of both sites and its adjacent areas. Further work continues with infiltration field tests using ring infiltrometer, at first theoretically for each method, and then practically with own personal measurements in the field. Further from the collected soil samples the measurements are performed in the laboratory, first in the permeameter, and followed by the grain size distribution test, from which the hydraulic conductivity is derived by using empirical formulas. At last the numerical modeling is used and all the results are compared. In the final phase of thesis the recommendations are given for infiltration at various locations and comparsion of the infiltration methods.

Splaveninová study of a selected flow
Zouhar, Radim ; Maleňák,, Jaroslav (referee) ; Veselý, Jaroslav (advisor)
The bachelor thesis focuses on determination of sediments amount in Svitava river and Křtinský potok, which flows into Svitava river in Adamov. Elements are sedimented at the riverbed bottom if the resulting force caused by the water stream on particles is smaller than the gravitational force. Elements can get into the stream both by washing from surrounding terrain and by material erosion of the riverbed which happens more frequently. Therefore another part of this thesis is suggesting of suitable stabilization measures and flood protection of selected objects. The capacity of riverbeds becomes smaller due to their sedimentation. Particle-size characteristics of sediment runoffs have been prepared and thus the amount of sediment runoffs has been calculated and critically evaluated.

Revitalization and flood control on the river Oslava and selected tributary
Kopuletý, Martin ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
The thesis is focused on the flood protection of the town of Oslavan on the river Oslava and its tributary Balinka. Sample samples were taken to determine the grain curve. The input data were obtained from the Povodí Moravy s. p. and were calculated in the HEC-RAS program. A level and flood analysis was developed and flood control measures were proposed. The flow was again calculated with the proposed measures and re-analyzed. At the end of the work the proposed measures were evaluated.

Compactibility of the materials for subgrade
Kolbábek, Jiří ; Varaus, Michal (referee) ; Stehlík, Dušan (advisor)
This thesis is focused on differences between compaction of fine-grained and coarse-grained soils. It presents selected compaction methods and it describes their principles and implementation procedures. In the practical part is performed classification of both types of soils and then samples are compacted by three methods. The result of this work is to compare the effects of compaction on fine-grained and coarse-grained soil.

Development of industrial floors with utilization of by-product
Radějová, Lucie ; Durica,, Tibor (referee) ; Bydžovský, Jiří (referee) ; Ševčík, Milan (referee) ; Drochytka, Rostislav (advisor)
This work deals with the use of waste materials in the development of new industrial floors. The main task of this work is to choose a suitable waste materials, and design a new material using such materials, while achieving the required physico-mechanical properties. The aim of this work is also to verify the effects of process application, suitable microfiller and final coat and propose a suitable alternative industrial floors, which would not only be in terms of economic efficiency, but also in terms of ecological suitable replacement for commercial products.

Assessment of soil quality processed with conventional tillage in the selected site in the Olomouc region
Drlíková, Barbora ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Diploma thesis documents the problems of soil quality, which is assessed on the basis of physical, chemical or biological indicators of soil quality. The paper describes the various indicators, its methodology and evaluation. In the practical part evaluates the quality of soil cultivated with the traditional way - using plowing. The experimental area, where the samples were taken from the soil, lies in the Olomouc region in the municipality Šumvald. Evaluated were selected physical, chemical and physico-chemical properties of soil, e.g. particle size distribution, bulk density, porosity, air capacity, hydrolimits, pH, carbonates, humus content and salinity of the soil.
