description: The subject of the graduate qualification work is âFiber-concrete based on the amorphous metal fiberâ. The work is devoted to the study of the physicomechanical properties of fiber-reinforced concrete based on a new and unexplored amorphous metal fiber and the development of the composition of fiber-reinforced concrete for use in the construction industry
The research set the following goals:
1. Testing of concrete samples reinforced with a new type of amorphous fiber, produced at the Peter the Great St.Petersburg Polytechnic University.
2. Testing of concrete samples reinforced with various types of commercial fibers.
3. Analysis of test results of amorphous fiber compared with other types of fiber.
4. A mathematical description of the dependence of the strength properties of concrete on the percentage of fiber.
5. Carrying out calculations to determine the stress-strain state of building structures using fiber-reinforced concrete based on amorphous metal fiber. 
Experimental studies to test fine-grained concrete and concrete using a full aggregate carried out in the laboratories of the SPbPU Engineering and Construction Institute in accordance with approved methods using certified equipment.
During the tests, such physical and mechanical characteristics as compressive strength and bending of fine-grained fiber-reinforced concrete and full-filled concrete, as well as electrical resistivity of samples of fine-grained concrete, were determined.
In addition to tests of fiber-reinforced concrete based on amorphous metal fiber, tests of fiber-reinforced concrete with commercial fibers were carried out and a comparative analysis was made with the results of tests of amorphous fiber.
Based on the experimental data, mathematical formulas are proposed for calculating the predicted strength parameters of fiber concrete with amorphous fiber.
On the example of calculating the interfloor overlap in the LIRA SAPR software packages, the testing of fiber concrete was demonstrated in the calculation and design of interfloor constructions.
As a result of the work, it was proved that this could be related to the design and construction of new facilities, as well as during the reconstruction and modernization of existing facilities.
