INVESTIGATION INTO ELECTRICAL CONDUCTIVITY OF THE MULTICOMPONENT SYSTEM OF TRACKBED

The article deals with the measuring results of the specific conductance of multicomponent systems which consist of more than three materials of various characteristics. As it was shown the electrical conductivity of systems composed of soil, slag and water depends in a lesser degree on the amount of slag and in a greater degree on slag's chemical composition. The value of specific conductance decreases when the amount of slag increases for basic slag, and increases for acid slag. For a system, which includes gravel particles coated with organic substances, the value of specific conductance correlates with the electric properties of the materials used, namely the function of chemical composition of the musticomponent system. Thus, there is a possibility to design a mathematical model for forecasting electric properties of multicomponent systems, which is based on an objective characteristic, namely, chemical structure of the materials used.
