| Abstract [eng] |
The aim of the master‘s thesis is to produce samples of thin-layer mineral composite hardened by CO2 gas using green technology and to determine its physical and mechanical properties. In order to achieve the research goal, 6 tasks were defined and described in the introductory part. The final work is divided into three main parts: literature analysis, research methodology, and the presentation and analysis of experimental results. The literature analysis describes the production of concrete and the main methods of product formation. Information was collected regarding carbonation technology, the methods employed, and the chemical processes occurring in concrete products during their carbonation. Moreover, after reviewing analogous studies, the influence of carbonation on the main properties of concrete, the influence of CO2 curing conditions on the efficiency and properties of carbonation, as well as potential applications in construction, were described. The research methodology part outlines 3 groups of samples: the first comprises cylindrical products, the second consists of factory pads, and the third involves thin-layered products. The description of the research methodology commences with the listing of standards used in the project and the description of the materials used. Each sample group is described individually by providing descriptions of sample composition, production, curing conditions and experimental tests, as well as formulas for calculations. The experimental results part presents and analyzes the findings obtained during the tests. In this part, an examination was conducted of the impact of curing with CO2 gas had on physical and mechanical properties of the samples, with a comparative analysis against air-cured samples. It was also analyzed how the properties of the samples vary by changing the type or amount of binder in the mixture. The master‘s final thesis is summarized by 8 conclusions derived from the results. The final document span – 67 pages, the work contains 56 figures, 18 tables, 58 literature sources and 1 appendix. |
