Program and results of experimental studies of the characteristics of fiber concrete produced by the mechanical technology of creating aggregate oriented fiber reinforcement

Abstract

Statement of the problem. The pace of development of modern construction creates the need to develop new technologies that make it possible to impart special properties to classical building materials, allowing them to expand the range of their application. The developed technology of mechanical distribution and orientation along the fiber fibers acting in the structure of tensile stresses in the body of linear fiber-reinforced concrete and fiber-reinforced concrete elements can provide more efficient use of fiber-dispersed reinforcement by including more fibers in the work of the section. It is necessary to develop a program of experimental studies of the strength and deformation properties of fiber-reinforced concrete in order to test the technology of laying fiber-reinforced concrete mixture developed by the authors. Results. A program of experimental studies of the strength and deformation characteristics of fiber-reinforced concrete, manufactured using the mechanical technology for creating aggregated oriented fiber reinforcement, is presented. The results of experiments carried out in accordance with the developed program are also presented. Conclusions. The presented program of experimental studies of the characteristics of fiber-reinforced concrete, made according to the technology developed by the authors for the mechanical creation of aggregated oriented fiber reinforcement, became the basis for experimental studies, the purpose of which was to test the technology developed by the authors for the mechanical laying of a fiber-reinforced concrete mixture with a uniform distribution of fiber fibers in a concrete matrix, as well as obtaining new data on the mechanical and deformative properties of such fiber-reinforced concrete.
