The given work is devoted to the research and development of the design of industrial floors made of fiber-reinforced concrete and obtaining the most advantageous floor design. The research set the following goals: 1. Study of physical and mechanical properties of fiber-reinforced concrete and selection of the composition of fiber-reinforced concrete for use in floor constructions. 2. Comparative analysis of test results and selection of the best option. 3. Carrying out calculations of the bearing layer of floors under the action of complex loads. 4. Economic justification of the design option. 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. As a result, floor structures based on fiber-reinforced concrete of various compositions were analyzed, calculations were made for the bearing layer of industrial floors. Efficient designs of industrial floors have been developed.
