The master thesis dealing with problematic about durability of concrete, with use of recycled concrete and addition of silica additions. Predominant for resistance of concrete constructions is surface layer, through which aggressive gasses and liquids penetrate from surrounding environment. The most important indicator of concrete durability is ability of surface layer transmissions of aggressive substants. In experimental part will be defined the actual state of surface layer by normal testing methods. The transmissions of surface layer will be tested on concrete cubes. Tests for transmissions of air (method TORRENT), of water (method ISAT), of acid gases (dept of carbonation by quick test in 98% CO2) will be carried out and also strength tests. Assessment of positive or negative influence of additions and amount of cement on durability and mechanical properties of concrete will be discussed in conclusion.

This final thesis is divided into two parts. The first, theoretic part is focused on issue about industrial concrete floors, their production and adjustment. Special attention is paid to the mineral shakes, steel fibres and concrete, which is used to these constructions. There are more information about specific standardized tests of steel fibre concrete and some damages of concrete floors in other chapters. Second part of the diploma thesis is practical. Theoretical knowledge are applied to the actual construction. Survey methodology and diagnostic work are also desribed. Data processing and evaluation with the commentary is also attached to this part. The conclusion summarizes the results and selected findings relating to the issue are also included there.

Master‘s thesis focuses on concrete combined with polypropylen fibres produced commercially, fibres without surface modifications and fibres modificated by plasma. Most important topic of the thesis is experimental verification of influence of plasma modificated fibres on attributes of fresh concrete and physical-mechanical attributes of solidified concrete. Based on the results of the tests perfomed on examin units compares results and anylyses applicability of different fibre surface modifications.

The subject of my master's thesis is construction technological project of the hall ADS s.r.o. Větřkovice. The work includes technical report of construction technological project, facilities of construction zone, solving traffic routes from the production to the place of construction, study of the implementation of the main technological stages of the building SO02, the most appropriate machine assembly, technological specification for drilled piles and for montage of prefabricated reinforced concrete skeleton, control and test plan, schedule of work, itemized budget, plan of the safety and health protection during work, proposals of design of movement mechanisms and time and financial discretion of realization of the reinforced areas of the production hall area.

The thesis deals with Komenského Street sports hall construction in Lysá nad Labem. Although partially dealing with construction of all parts, in detail it studies gym construction, focusing on time management, technology and resources of implementation. The thesis is divided into the drawing and text parts. The former includes site facilities design and building situation. The latter consists of the main part construction project implementation study, itemized budget, time schedule, technological regulations, inspection and testing plan for the implementation of the main construction part 1st floor reinforced concrete columns and walls, construction machines and mechanisms design as well as time and financial schedule.
