Improvement of rheological properties of soil structure based on lignite dispersion

Abstract

This article examines the change in stress and strain media, in particular natural leonardite (brown coal), prepared for grinding and during grinding, due to the restructuring of the material, i.e. changes in the relative position and deformation of the elements of the structure, including at the level of macromolecules that are inert to the deformation and relaxation processes, provide important for the technology to use improved rheological properties of the soil structure based on dispersion of leonardite, information about the physical properties of the material and its structure. The time variation of the stress in an inert-viscous-elastic medium with a constant strain rate depending on the values of the rheological parameters, it is possible to occur by three laws: aperiodic (steady), critical and oscillatory damp.
