Reactive powder composites and cement composites without macropores
Panenková, Monika ; Hela,, Vlastimil (referee) ; Hela, Rudolf (advisor)
This diploma thesis deals with the design principles and manifacture of ultra performance concrete (UHPC), reactive powder composites (RPC) and other fine-grained materials, such as Macro defect free (MDF) or Densified systems with small particles (DSP). Theoretical part of this work is focused on the requirements of properties and composition UHPC and RPC and methodology of their design principles. Experimental part describes design principles RPC, manufacture of test specimens, testing of certain physical and mechanical properties, such as tensile strenght, bending strenght and compressive strenght and determination chemical character X-ray and thermal analysis.

Current development of UHPC concrete and verification of selected properties
Panenková, Monika ; Sedlmajer, Martin (referee) ; Křížová, Klára (advisor)
This bachelor thesis deals with current developments and research in the field of ultra high performance concrete – UHPC. Theoretical part of this work is focused on the composition and properties of UHPC compared to normal strength concretes. It describes design principles, constructions in the world and also in the Czech Republic and other use of this material. Experimental part describes the design of UHPC, manufacture of test specimens and testing for certain physical and mechanical properties such as compressive strength, tensile strength, bending strength, water impermeability, frost resistance, resistance to chemical de-icing substances and abrasiveness of the material.

Analysis of the Ultra-High Performance Concrete Stair Thread
Lisztwan, Dominik ; Daněk, Petr
In this contribution, experimental and numeric analysis of slender stair tread model made of an ultra-high performance concrete, is described. Task of the analysis is to determine the behaviour of the model under acting load. The experimental part is represented by the static load test with the use of a vacuum method. Besides that, nonlinear numerical analysis in the environment of the ATENA Science software, is described. Gained results from both parts of the analysis are compared and unusual behaviour of the model is discussed.
