The thesis deals with the possibilities of use of construction and demolition waste in the Czech Republic and focus on the method of using recycled track ballast concrete in the SŽDC's construction. The theoretical part of thesis provides an overview of recycling methods used in construction. The practical part focused on how to use con-struction waste at a specific site and compare the alternatives construction waste management, from an economic and environmental point of view.

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.

Energy by-products are very interesting source of raw materials for the production of various kinds of building materials in the Czech Republic. Due to annual production of volumes and also markedly more stable quality is needed more to enforce their utilization. Work provides a unique comprehensive perspective on energy by-products in the Czech Republic. The work assesses really wide spectrum not only domestic energy by-products both from the physico-mechanical or physico-chemical parameters so from point of view of the variability of their properties, structure evaluation or environmental performance. Another important benefit is extensive and complex evaluation of the suitability of an almost complete ash production of company ČEZ for both basic types of artificial aggregates based on fly ash. The work represents a practical view of the producer of energy by-products on the comprehensive problems of power plant operation, material flows and mainly on usability of energy by-products in building materials. Illustratively are presented studies of economic and ecological advantages of substitution conventional raw materials by secondary energy products. The work deals with the issue of optimizing legislative regulations of the Czech Republic, implementation of the regulation European Parliament, for maximum simplification and streamline the process of certification of products based on energy by-products.

This diploma thesis deals with monitoring the properties of concrete with carbon nanoparticles. The theoretical part describes properties of nanoparticles, their dosing and dispersion. In the practical part of the diploma thesis the physico-mechanical properties of the concrete with the addition of carbon nanotubes were determined after 7 and 28 days of aging. The frost resistance test was then determined after 100 cycles. All results were compared with the reference samples.

Theoretical part of diploma thesis deals with progressive building materials, namely with aggregate from foam glass. Resources for production, description of production, properties of aggregate and its utilization are included. Production of lightweight gaping concrete, its properties, risks during its production and utilization in building practice are part of diploma thesis as well. Lightweight gaping concrete was made during practical part. It was produced by combining aggregate from foam glass and cement. Testing of required properties was carried out on these made samples.

This diploma thesis deals with concrete abrasion resistance against abrasion. The constructions of transport and water management structures are most stressed by the action of abrasion by means of travel of vehicles and flowing water. Abrasion reduces the durability of the structures. The prerequisites for achieving the best possible abrasion resistance are examined. Furthermore, test methods that are currently used worldwide. The experimental part deals with the influence of individual types of aggregates amphibolite (Želešice), fecal gravel sand (Žabčice) and basalt (Bílčice) on abrasion resistance. Furthermore, the dependence between the strength of the concrete and the hardness of the surface for abrasion resistance. Abrasion resistance testing was determined by concrete abrasion, abrasion resistance by the Böhm method and by water jet.

The thesis is focused on the design and assessment of two variants of tanks for wwtp. For comparison, a reinforced concrete tank and a prestressed concrete tank were designed. The work includes a data accompanying report for the static calculation and a technical report on the construction, static calculation and drawing documentation of shapes and reinforcement. The calculation of internal forces on the structure was performed in the SCIA Engineer 18.1 calculation software.

The final thesis designs an apartment building with terraces, bikeshop and underground garage. The building is situated in the city of Hradec Králové. Building has four floors and one underground floor. The main root area is designed as extensive green roof. The supporting system consists of a cast-in-place reinforced concrete frame with masonry of brick blocks. The whole building will be insulated by external thermal insulation composite system of mineral fibers. The building design meets the requirements for almost zero energy consumption houses.
