Description
Summary:IR thermography and gamma-ray method were used to experimentally study motion of thermal and moistening fronts in a porous material under capillary moistening. It is shown that at capillary moistening propagation of the moistening front may be accompanied by the thermal front due to sorption processes. On the basis of obtained experimental data the relation between propagation of two fronts has been established.
