| Abstract [eng] |
The objective of the master’s thesis is to produce wood-concrete biocomposites using 0/5 mm fraction wood processing waste and mineral binders and to determine the physical and mechanical properties of the resulting biocomposites. The master's thesis consists of 3 separate parts: literature analysis, research methodology and research results and discussion. The literature analysis part identifies the shortcomings of the use of organic materials in the production of biocomposites, possible physical and chemical solutions, and reviews the technology for the production of lightweight artificial aggregates. The research methodology part describes the materials used in the research, the compositions of lightweight artificial aggregates and biocomposites with lightweight artificial aggregates, the applied studies, and the course of the research. The research results and discussion part present the results of the research, indicates the physical and mechanical properties of lightweight artificial aggregates, describes the physical and mechanical properties of biocomposite samples with lightweight artificial aggregates, and provides calculations of the CO2 footprint. The research has shown that the use of lightweight artificial aggregate in the production of biocomposites has a negative impact on the compressive strength, shrinkage deformations, and frost resistance properties of biocomposites. Products with lower density are also obtained. However, the use of lightweight artificial aggregate has a positive impact on reducing the CO2 footprint. The results obtained in the final thesis can be used in further research into biocomposites with a lower CO2 footprint. The volume of the master's thesis is 72 pages without appendices, 26 tables and 38 figures. 66 literary sources were used in the master's thesis. |
