Abstract Thinly-dispersed frozen, freezing and thawing-out soils were studied for developing a physicochemical theory about formation of mass-exchange and thermal properties of cryogenic soils. An original complex of methods and facilities was developed for studying cryogenic processes in dispersed soils. Forms of water bonds in frozen soil and regularities of quantitative content of nonfrozen water were determined. Existence of physicochemical characteristics of temperature constants in frozen soils is established. Mechanisms of the following processes were described: cryogenic moisture transfer in freezing soils, anomalous temperature expansion-compression process, and hysteresis of the dependence of heat conductivity of soils in their freezing and thawing out, and others.
