Abstract

The porosity of clay-rich materials is well known for bulk samples, but the direct characterization of pore morphologies at nm-scale in very fine-grained samples is difficult due to sample preparation. In this study, the combination of Broad-Ion-Beam (BIB) cross-sectioning and SEM-imaging was used to produce high quality, polished cross-sections and image pores down to a few nm in size. Three samples of Boom Clay from the Mol-Dessel reference site for radioactive waste disposal (Mol-1 borehole, Belgium) were investigated and compared with regard to their porosity and grain-size.
