description: The subject of the graduate qualification work is "The effect of crystal-forming additives on the physical and mechanical properties of concrete". The work is devoted to the study of the physical and mechanical properties of concrete with the use of crystal-forming additives. The research set the following goals: 1. Analysis of scientific literature on the effect of crystal-forming additives on the physical and mechanical properties of concrete. 2. Selection of tests for the study of physical and mechanical properties of concrete. 3. Production of samples for testing physical and mechanical properties. 4. Conducting tests to determine frost resistance, water resistance and strength. 5. Analysis of test results to determine the physical and mechanical properties of concrete. Experimental studies were conducted on the basis of the educational laboratory "Additive Technologies and 3D Printing" of the SPBPU Institute of Civil Engineering and the accredited scientific testing laboratory "POLYTECH-SKIM-TEST" in accordance with proven methods using certified equipment. During the tests, such physical and mechanical characteristics as compressive and tensile strength during bending, frost resistance and water resistance of concrete were determined. For tests to determine frost resistance, the software and hardware complex "KONTAR - Console" was used. According to the results of experimental studies, it was concluded that crystal-forming additives show an increase and resistance of concrete against corrosion and frost destruction, which indicates the possibility of a significant increase in the durability of structures.
