The processes of shrinking of capillary-porous colloidal bodies under 
the action of capillary-osmotic pressures have been investigated. 
The mechanisms of densification and strengthening of a material in 
the drying process have been considered. An equation relating the 
material's strength to its density, which agrees with experiment, 
is proposed.
