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