- Abstract
We study the influence of temperature, stresses, and resistivity of a foam masses on the intensity of moisture removal. We select three zones of changes in the electric resistivity. The distribution of the pressure field is connected with the filtration of moisture in capillary-porous materials. For the insufficient structural strength of interporous partitions and sharp changes in temperature, we observe the phenomenon of subsidence of the foam masses. We analyze the character of changes in membranes for the maximum possible increase in the volume of the pore and evaluate the volume of refractory component, which forms the shells of pores (cells). The filtration of liquid in the analyzed foam mass under the action of pressure gradient is characterized by its viscosity and the geometric parameters of the capillary-porous body. In the case of self-compaction of the foam system, the process of mass transfer becomes more complicated due to the changes in the filtration characteristics of the matrix. In order to exclude the stressed state in the adobe body after electric heating, the body should be gradually cooled down to a temperature safe for its structure.
