Described the experimental setup and presents the results of theoretical and experimental analytical studies of structural characteristics (coefficient of fully wood - porosity or the porosity) and physico-mechanical properties (coefficients of internal and external friction) of the materials crushed wood, a generalization which allowed us to obtain the calculated dependences for determination of their size by volume of bunkers axisymmetric geometry.
crushed wood, the porosity, the bunker, the coefficients of internal and external friction
