AbstractAbout AuthorsReferences
The stress-strain state of fiber-concrete water-sewer pipes made by the method of dry vibro-pressing is considered. Laboratory tests of fiber-concrete samples for compression, bending, crack resistance, stretching and splitting were carried out at the testing site. The main purpose of the research is to determine the optimal amount of fiber in the pipe and the necessary design mechanical characteristics of the fiber concrete. The elastic modulus, Poisson’s ratio and tensile loads were determined. 3D steel fibers were used in the test and the results of the fiber concrete pipe test are presented. The results of testing of fiber-concrete pipes with different steel fiber content (20, 30 and 40 kg/m3) made it possible to determine the optimal composition of fiber-concrete. An overabundance of fiber leads to the separation of the concrete structure, which reduces its resistance.
