A CONTRIBUTION TO THE THEORY OF POROSITY OF FINE-GRAINED SEDIMENTS
J. G. Dueck,a D. Purevjav,b and D. Yu. Kilimnikc UDC 539.6,539.217 The influence of adhesive forces on the structure of sedimentation layers has been considered. A theoretical model allowing calculation of the porosity of a sedimentation layer as a function of the particle size, the layer thickness, and the adhesive-force level has been developed. Experiments in which these variables were changed have been carried out. The adhesive force was varied by changing the concentration of the electrolyte. A quantitative agreement between theory and experiment is observed for the porosity as a function of the particle size and the layer thickness; for the porosity as a function of the adhesive force this agreement is qualitative. aErlangen-Nurnberg University (Universitat Erlangen-Nurnberg), D-91052, Erlangen, Germany; email: Johan.Dueck@uvt.cbi.uni_erlangen.de; bMongolian State University of Science and Technology, Ulan Bator-46, Mongolia; c N.
