In situ observations of the swelling of bentonite

The microstructural evolution and hydraulic conductivity of bentonite in NaCl solution is investigated by in situ laser scanning microscopy (LSM). Upon exposure to saline solution, the bentonite aggregate swells rapidly, followed by a longer period of more gradual swelling. The expansion ratio of an aggregate reached a steady state 15 min after initial exposure to the …
