description: The topic of the final qualifying work is "Building mixes for 3D printing". The work is devoted to the development of the composition of the building mix in order to use it for a construction 3D printer. Tasks that were solved during the research: 1. Analysis of the literature on the topic of testing building mixes and research on the requirements for formulations for a construction 3D printer. 2. Analysis of regulatory documentation on the methodology of testing the properties of building mixes for 3D printing. 3. Selection of several compositions of mixtures with various components for a construction 3D printer. 4. Production of samples for subsequent physical and mechanical tests. 5. Analysis of the results obtained, selection of the optimal composition for a construction 3D printer. 6. Printing on a construction 3D printer using the selected mixture composition. Experimental studies on the testing of compounds were carried out in the laboratories of the SPbPU Institute of Civil Engineering in accordance with proven methods using certified equipment. During the tests, such physical and mechanical characteristics as compressive strength and plastic properties of the material were determined. In addition, the effect of the addition of components such as metallurgical slag, various types of cement, fiber and gypsum on mechanical and rheological properties was analyzed.
