The purpose of this study was to explain the reason of the FID signal intensity change for soil samples in the positive temperature range (0-40°C). According to the reference data the main cause is the presence of the paramagnetic ions in soil. The experiment conducted on 4 cohesive soils showed that the main reason of FID changing could be the change of the water’s heat of the vaporization, decreasing...
A series of experiments on samples of five clayey soils gave evidence that cyclic freezing and thawing significantly affects the permeability coefficient. An attempt to analyze these changes on base of the Scanning Electron Microscopy SEM photographs of microstructures has been made. A simplistic equation (Eq. 11) has been drawn, describing the permeability coefficient as a function of hydraulic radius...
In the method of thermoporometry, the characterization of pore space is done by analysis of thermal effects associated with freezing and melting of a liquid in the pores of the material under investigation. Thermoporometry seems particularly well suited to studies of wet porous samples in cases where the process of drying itself is able to destroy the original microstructure, as is the cohesive soils...
