| Abstract [eng] |
The aim of the final thesis research is to produce biocomposites with various binding materials and organic waste, which are further processed before use, and during the experiment, to determine the physical and mechanical properties of the obtained materials. The main binding materials used are lime and cement, and the organic waste includes wood shavings and pyrolyzed wood. The thesis consists of an introduction, literature review, sample compositions, production description, research methodology, results, and conclusions. The literature review examined the concept of biocomposite, the influence of different organic materials on the mechanical, physical, and thermal properties of samples, and the impact of additional preparation of organic materials on the final product. The possibilities of using biocomposites were also analyzed. The following section provides information on the compositions of the formulated biocomposites, the production process, and the experiments conducted during the final thesis. The experiment revealed that wood has a high water absorption capacity, requiring additional preparation of organic materials before making the biocomposite mass. Artificial filler analysis using a scanning electron microscope revealed that the contact zone between organic materials and the binder is weak. The density of compressed biocomposites is in the range of 749−1263 kg/m³, while the density of concrete with organic material filler is 1500−1727 kg/m3. The compressive strength test showed that the use of organic materials significantly reduces the mechanical properties of the biocomposite. In the final section, conclusions are presented regarding the literature review, the impact of additional preparation on biocomposite properties, the mechanical and physical properties of samples, and potential applications. The final master's thesis is 51 pages long. The thesis consists of 13 tables, 43 figures, and 47 literature sources. |
