| Abstract [eng] |
The aim of the master's thesis is to create a cement-free carbonized product and determine its physical and mechanical properties as a paving element according to the testing methods for concrete outdoor paving stones specified in the LST EN 1338 standard. 3 tasks were set to achieve the aim of the thesis. The thesis consists of three main parts: literature analysis, research methodology and research results. The literature analysis part describes the CO2 curing technology, accelerated carbonization methods, the influence of binders and materials on carbonization, as well as the physical and mechanical properties of carbonized products, their CO2 gas emissions and the production technology of pressed products. The research methodology part describes the materials used, the composition of the samples, and their production process. The course of the research methods is also described and the formulas used to calculate the results are presented. The research results part describes and analyses the results obtained during the research. First, according to the compressive strength of the samples and the depth of carbonization, the composition that showed the best indicators was selected, which was further improved and studied by the tests described in the research methodology section. The physical and mechanical properties of the most optimal composition were determined and its CO2 gas absorption rate was calculated. The master's thesis is summarized in 7 conclusions. The volume of the thesis is 51 pages, the work contains 35 figures, 5 tables and 48 references. |
