The swelling behaviour of expansive clays is strongly related to the interaction between clay particles. In this paper, a series constant-volume pressure and mercury intrusion porosimetry (MIP) tests were carried out on MX80 bentonite/Callovo-Oxfordian (COx) claystone mixtures with different bentonite fractions dry densities. Results show that increased linearly increase in density. Additionall...

NMR measurements on core samples saturated with brine returns valuable information on the porous structure of the rock core. Monitoring a single fluid component in a relaxation experiment reflects the pore size distribution and thus the degree of sorting of the porous rock. The basic assumptions are that the mobility of the component confined in the porous rock is of such a value that a small f...

Pore network models are used to relate fundamental pore structure parameters (pore body and pore throat size distributions) to the distribution of water at the pore level and the decay of proton magnetization under conditions of primary drainage in water-wet rocks. The simulations reveal conditions under which diffusive coupling between pores has a significant effect on the decay spectra and pr...
