description: The work is devoted to the study of the physical and mechanical properties of concrete, where slag was used as a binder and the development of a mixture composition for construction printing for use in the construction industry at temperatures below 0 Â° C. 1. Selection of composition based on slag, selection of activator 2. Design of concrete compositions with different types of fine aggregate and analysis of the results obtained. 3. Manufacturing of samples for physical and mechanical tests. 4. Testing of samples and analysis of the results obtained. 5. Selection of the composition of concrete with the addition of fiber, granulometric slag as a fine aggregate, testing, analysis of the results. 6. Analysis of the results obtained, selection of the optimal composition. Selection of antifreeze additives. 7. Testing of samples with the addition of fiber and antifreeze additive to the selected optimal composition and analysis of the results. 8. Printing on a construction 3D printer. During the tests, such physical and mechanical characteristics as compressive and flexural strength were determined. In addition to the compression and flexural tests of slag-based concrete, frost resistance tests were carried out. A sample was also printed on a construction printer. Based on the results of experimental data, a mixture composition for construction printing was proposed, which can be applied at temperatures below 0 Â° C. The mixture was tested on a construction printer located in the SPBPU laboratory. As a result of the work, it was proved that the created mixture is applicable for construction printing and can be used in the construction of facilities.
