Possibility of determination of rheological properties of fresh concrete by penetration needle
Driml, Martin ; Sedlmajer,, Martin (referee) ; Zach, Jiří (advisor)
This thesis focuses on the method of determining the rheological properties of fresh concrete with a penetration needle. An assessment conducted in this thesis aims at current methods of determining the rheological properties of fresh concrete in terms of theapplicable technical standards. These methods are compared with the needle penetration method. This method is characterized with it's simplicity and low requirements for measurement rechniques. Therefore it can be used directly on site without any problems.

Influence of Initial Conditions on the Modulus of Elasticity of Concrete for Bridges
Blažek, Michal ; Bílek,, Vlastimil (referee) ; Cikrle, Petr (advisor)
Beside the compressive strength of concrete, which is considered as the basic parameter parameter for design of concrete structures a modulus of the concrete elasticity should be set as well. This thesis deals with influences, which are acting on the concrete, particularly within the initial stage of its hardening (i.e. within 28 days after casting). Nowadays, when time is the most valuable factor, some knowledge is required about mechanical properties of concrete earlier than after above mentioned 28 days and to apply them advantageously. The concrete in initial stage of hardening is influenced by many factors that affect progress of the elasticity modulus during the course of the time. For understanding of these problems a literature search was performed, as well as the experiment demonstrating the effect of temperature on the modulus of the concrete elasticity. The effect of temperature on the modulus of elasticity of concrete in initial stage of hardening has not been intensively studied yet. Therefore, more attention is paid to it by this elaborate. The experiment investigated the static and dynamic elastic modulus of concrete, whose recipe is similar to one used for production of prefabricated and prestressed bridge girders.

Activation admixtures in concrete
Eger, Lukáš ; Hela, Vlastimil (referee) ; Hela, Rudolf (advisor)
The aim of my bachelor´s work is the summarization and focus on admixure concrete,and the active and inert admixure, which have some positive characteristies for fresh and hardened concrete. Theoretically, I tried to study the increase of their joining potential while this characteristic can be used by either chemici or mechnical way, their combination as well. I also Works on evaluetion of physically mechanical influence for fresh and hardened concrete that can up to 60 days old while the cement was partly substituted by admixure of different character.

Reinforced concrete skeleton construction
Prokop, Lukáš ; Ing. Ivana Laníková, Ph.D (referee) ; Šulák, Pavel (advisor)
The bachelor work is aimed on designing of reinforced concrete, monolithic, locally supported floor slabs and fire effects on concrete constructions. Ceiling construction is located on the first floor. Calculation of internal forces is carried out in the Scia Engineer software. There is prepared drawing of the shape and drawing of the ceiling construction. In addition there are mentioned examples of evaluating the effects of fire on concrete constructures.

Part of load-bearing structure of multipurpose building
Anděl, Martin ; Jeneš, Rostislav (referee) ; Terzijski, Ivailo (advisor)
The aim of this project was to design a part of a load-bearing structure of a multipurpose bulding. The load-bearing structure was designed of transversely oriented monolithic reinforced concrete multi-storey frames. These frames are in each storey connected by a continuous floor slab. Both design and relevant drawing documentation of a continuous floor slab, beam, column and a column footing was made in this project.

SMS Enterprise Premises
Kopřivová, Nikola ; Šuhajdová, Eva (referee) ; Myslín, Jiří (advisor) ; Čuprová, Danuše (advisor)
The building for small and medium business is located on the outskirts of the city of Brno in Modřice. In close proximity there is a shopping center Olympia, Giga Sport and discount furniture. The building is designed as a compact mass, which is divided horizontally into two different sectors of manufacturing industry and administrative offices. The production hall is vertically extends through the first two floors and part of her administration is appropriate in the southern part of the building. In the northern part of the premises is located warehouses and production supply. The third floor is a separate space for administrative purposes with its own entrance from the eastern part. The building meets the standard for low power consumption and a flat roof can be used to store solar collectors for energy and hot water. Each location in the building is wheelchair solved. The facade is divided horizontally by three colors black, gray and white. Window are designed as french windows vertical contrast to the color of the facade. The building offers maximum versatility, functionality and potential jobs

Spatial stained sheet of glass on a dream
SOMMEROVÁ, Zuzana
This thesis deals with a dream. It is divided into two parts, theoretical and practical. The theoretical part consists of basic knowledge of the dream in terms of physiological and psychological. There is also mention the phenomenon of dreams as a source or subject in the historical development of visual arts. The theoretical part also discusses author?s personal relationship to dreams, the choice of materials, techniques and rationale for selection of space for indoor installation. Practical part of the author's realization of spatial stained glass plate combined with concrete. Workflow is completed the drawing designs and photographs.
