Abstract

This study covers the shear strength measurements of very fine pressure filter cakes of TiO2, calcite fractions, labosil, kaolin and synthetically prepared glass spheres, The shear strength behavior of all these cakes at the full range of saturation, i.e. from S=0.0 to S=1.0, showed the same tendency as in the case of Schubert's diagram for the tensile strength of the mineral filter cakes. The dependence of the shear strength of the filter cakes on the used pressure, particle size and shape has been analyzed. The effect of a surfactant (Lutensol TO3) treatment on the shear strength of the cakes was also investigated.
