The major laps of the soil solid phase and pore transformation during the cycles of freezing and thawing were considered in the laboratory conditions. With the help of X-Ray computer tomography we studied the dynamics of micromorphological pore composition in the aggregate d = 3 mm from the humus layer of the soddy-podzolic soil at the capillary moistening and the following 1, 5, 10 and 20 times freezing (–10°С) and thawing (+20°С). We showed that during the capillary moistening the total porosity of the aggregate, which was measured on the tomographic reconstructions, is increased by more than 2 times (from 6.5 to 15.4%). During 1, 5 and 10 cycles of freezing and thawing the constant decrease of pores number and their average sizes occurs. There is also observed the decrease of the total tomographic aggregates porosity to 13.7, 10.6 and 5.6% correspondingly. After the 10 cycles of freezing and thawing the relative stabilization of the inner aggregates composition occurs. The volume of pores with inclusions of ice was decreased to the air-dry level. The micromorphometric analysis showed that the single freezing doesn’t lead to the significant changes in the form of aggregate and pores. After the five cycles of freezing and thawing the deformation of the aggregate and changes in the form of inner aggregate pores occurs. After the 10 times freezing and thawing the sloughing of aggregate occurs, the total porosity decreases, pores with crack-like form disappear, and the numerous vesicular pores occur. After the 20 cycles of freezing and thawing all of the inner aggregate pores obtain the roundish weakly dissected and vesicular form. The low sustainability of humus aggregates to the cyclic freezing and thawing corresponds with their low mechanical stability.
