Аннотация
This article investigates the physical and mechanical properties of heavy concrete reinforcedwith non-metallic dispersed fibers, as well as the specific features involved in calculating concrete structuresbased on such materials. The study analyzes the influence of various types of non-metallic fibers, includingpolymer, basalt, and glass fibers, on the strength characteristics, crack resistance, and deformation propertiesof concrete. In addition, the behavior of fiber-reinforced concrete under loading conditions is substantiatedthrough both experimental and theoretical approaches.The paper also highlights the factors that should be considered in the design and calculation of suchconcrete structures, which differ from conventional calculation methods. These factors include the volumefraction of fibers, their interaction with the concrete matrix, and the characteristics of stress distribution withinthe material. The obtained results possess both scientific and practical significance for the effective applicationof non-metallic fibers in concrete and for improving the durability and reliability of building structures.
