Survey and Diagnostics of Brick Structure
Brothánek, Jan ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The diploma thesis deals with a structural and technical survey of the surviving cellar of the German House in Brno. The first part of the thesis is devoted to the theoretical description of the constructions, methods performed and their evaluation concerning the investigated space. The aim of the survey is to determine the strength characteristics of the masonry and on their basis to propose appropriate rehabilitation and structural protection.

Preparation and Realization of Technical Survey of the Building
Brothánek, Jan ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
This thesis covers structural-technic research of family house situated in Brno. In the first part of thesis I discuss theoretical explanation of structures situated in the object and its assessment in vterms of structural engineering research. Goal of this research is to estimate strength of masonry. These properties are calculated in practical part of this thesis. Last part of thesis summarizes previous calculations of strength of masonry.

Methodology of historical bricks and masonry tests
Bartoň, Vojtěch ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
This diploma thesis is focused on methodology for sorting of solid fired bricks for reconstruction of historical buildings. The theorethical part of this thesis includes description of production technology of solid fired bricks and diagnostic methods. In practical part there are these methods aplied on the solid fired bricks, which are intended for reconstruction of the bridge in Sedlec. There are monitored changes in structure of solid fired bricks caused by repeated freezing and defrosting. This changes are monitored by resonant frequency method and ultasonic pulse method.

Impact of injection on mechanical and physical characteristics of mortar
Fridrich, Pavel ; Myslín, Jiří (referee) ; Tomíček,, Oldřich (referee) ; Klečka,, Tomáš (referee) ; Tuza, Karel (advisor)
The increased moisture of the building materials causes the change of its mechanical and physical characteristic. In particular the high amount of loose water in construction shorten the lifetime of the building, is harmful to human beings due to biotic factors and increase the economic expenses of usage of the building. Apart from the costs of rehabilitation the loose water deteriorates the thermal insulative ability (thermal conductivity coefficient ) of perimeter masonry as well. The moisture gets into masonry not only through its deffects but also due to many different reasons. In order to improve the utility value of the buildings we have to deal with the rehabilitation of damp masonry with view to all possible causes. Only the properly working damp proofing ensures the protection against the water leaking from the subfoundation of the building. One of the direct techniques which have undergone rapid progress in last few years is the injection procedure. With use of experimental methods in my dissertation I deal with evaluation of two injection compounds used in Czech Republic and with its impact on the characteristics of the mortar. With the modern hollow bricks (system THERM) it is possible to create horizontal infusion into the lateral mortar grooves in future.

Survey and Diagnostics of Building Construction
Černý, Jan ; Komárková, Tereza (referee) ; Anton, Ondřej (advisor)
This bachelor thesis deals with the issue of diagnostic exploration of the railway vault bridge on the track section 2201 Nezamyslice - Olomouc hl. n., a registration kilometer of 69,982, also known as the "Vysoká pivínská klenba". In the theoretical part is described the problems and the systematicity of diagnostic methods for masonry structures. The practical part focuses on the processing and evaluation of the diagnostic survey, which results in determining the material properties of the structural elements.

Preliminary survey and assessment the building before renovation
Bartoň, Vojtěch ; Stehlík, Michal (referee) ; Cikrle, Petr (advisor)
This bachelor thesis deals with the construction and technical survey of a masonry building with cast iron columns. Construction-technical survey was carried out, due to the planned conversion of the building into a apartment building with public services. The thesis contains description of construction and technological survey and diagnostic methods, which includes evaluation of essential characteristics of masonry structures and cast iron columns. The practical part contains processing of diagnostic survey. Its result is determination of material and geometric characteristics of the structure.

Specific cement composite based on secondary raw materials with emphasis on durability
Figala, Petr ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
Nowadays the attention to the utilization of secondary raw materials as a component of building materials is being paid to in the Czech Republic and in the world. This thesis deals with possibilities of using secondary raw materials as partial cement substitutes in industrial floors. The aim of this thesis is to verify the influence of cement substitution amount with secondary raw materials and their fineness of grinding on the properties of the floor surface in time and on its structure. On the basis of the acquired knowledge, the influence of the pre-treatment of the secondary raw material on the properties of the floor ceiling with an emphasis on the economic aspect was assessed. After evaluating the results, some substitution of cement in the floor screed with secondary raw materials is beneficial. The significant influence of more intensive milling of the floor screeds base on the parameters of the final floor screed was not confirmed. It seems, that it is possible to achieve very good results even when using secondary raw materials with a lower percentage of fine particles. This brings together the economic benefits of lowering the cost of a lower dose of expensive cement by using cheaper secondary raw materials, because pre-treatment of such materials does not require the use of a large amount of energy.

Mortars with Alternative Materials
Kozielová, Silvie ; Sokola, Lubomír (referee) ; Žižková, Nikol (advisor)
This bachelor’s thesis deals with building material mortar. These are mainly the use of waste materials from industry to replace part of the filler or binder to produce mortar. The theoretical part deals with information about the classification and properties of mortar on their ingredients and methods of use. Collectively describes alternative raw materials suitable for use in mortar production and trends of our time for its production. The practical part is focused precisely on the use of alternative raw materials to replace part of the filler or binder to produce mortar. Evaluated and compared with the properties achieved by the mortar with the selected raw materials waste.
