Testing of bricks intended for the repair of monuments
Lezová, Lívia ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
The bachelor thesis is focused on methods of testing bricks, which will use to classify historic bricks into groups on usable, usable in extreme conditions, usable in limited extent and unusable for restoration of monuments or for construct new constructions. In the theoretical part, there is describe of historical development of solid fired bricks in Central Europe and an overview of methods for testing bricks, including a description of an accomplishments and their evaluation. In the practical part, there are methods applied to three visually different sets of bricks taken from 19th century construction.

Survey and Assessment of highway D2 Bridge
Výpustek, Libor ; Suza, Igor (referee) ; Cikrle, Petr (advisor)
This thesis deals with the exploration and evaluation of the existing bridge carried him on the highway D2. The work is divided into theoretical and practical parts. The theoretical part focuses on the technical surveys, diagnosis of building structures and some methods of investigation and testing of building structures. In the practical part the visual inspection and diagnosis of disorders of the highway bridge substructures ev. No. D2-058, to determine material characteristics substructure and evaluate the state of the bridge. In conclusion, the practical part of the recommendations for the design and method of repairing the bridge.

Experimental research of suitability and durability of sealants used in civil engineering
Hanzelková, Martina ; Schmid, Pavel (referee) ; Sedlák,, Petr (referee) ; Šlanhof, Jiří (advisor)
The dissertation thesis is focused of the method of testing the building sealnats. This is a summary of the research focused on the evaluation of sealants in interaction with the underlying materials. Attention is focused on the official test methods contained in European technical standards, the benefits of individual methods, their advantages and disadvantages are discussed. Also included are the overall findings of the practical application of the test procedures applied to 10 commercially available industrial sealants on 8 different substrates, including facade lining boards used for lightweight envelope systems. The dissertation thesis contains general conclusions about individual test methods. The research also includes various ways of preparing and conditioning test specimens that simulate different environmental conditions and, in some cases, play a crucial role in the final evaluation of sealants.

The issue of the revision corrected wiring residential building
Štefek, Roman ; Janda, Marcel (referee) ; Veselka, František (advisor)
Bachelor’s thesis deals with the verification of electrical installations in residential buildings. The task of the thesis is to get acquainted with the requirements of the regulations with a focus on Czech technical standard CSN 33 2000-6, CSN 33 1500 and follow-up. Specifically, the information gathered is used to the implementation of the review installations in renovated apartment building. The aim is to apply the theoretical knowledge and information for the practical verification of the electrical installation.

Methods for the survey reinforced concrete bridges
Ehrenberger, Ondřej ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
Policies and types of diagnostic examination of a bridge. The theoretical section contains review diagnostic methods for a steel concrete frameworks. In a practical section there is made a examination of a bridge object over a river Moravia and a suggestion of the examination according to the detected defects. In the experimental section we are discovering, with a help of georadar, a location of reinforcement of a monolithic wall and board.

Metody hodnocení a zkoušení medu s důrazem na jeho jakost a pravost
Kučerová, Tereza
This bachelor thesis is concerned with the methodology of honey evaluation and testing. It characterises the different components contained in honey and its properties. The thesis deals with the determination of these parameters and presents methods for their determination. It describes mainly the chemical and physical analysis, which includes sensory analysis, determination of water content, determination of sugars, sucrose content by polarization, 13C/12C isotope ratio, hydroxymethylfurfural (HMF), antioxidant content of electrical conductivity, thiric acidity and pH. The last part includes microscopic analysis and characterization of microorganisms in honey.

Diagnosis of connected concrete layers by pulse echo method
Lokos, Ondřej ; Kocáb, Dalibor (referee) ; Cikrle, Petr (advisor)
This study deals with the measurement of the adhesion of the upper concrete layer to the underlying layer in a truck parking lot. The pulse echo method is used to detect de-laminations of whitetopping. The aim of the work is to verify the efficiency of this meth-od and its accuracy in measuring the adhesion of the concrete layer. The results of the measurements are compared with the results of the measurements on the test block. This study contributes to a better understanding of the coherence of the concrete layers and may help in improving the design and maintenance of truck parking lots.
