Experimental evaluation of the influence of saturation media on the mineralogical and physicochemical stability of bentonites

Popis výsledku v původním jazyce

Three bentonite buffer materials (Rokle bentonite, FEBEX bentonite, and Mock-Up-CZ mixture composed of 85% Rokle bentonite, 10% silica sand and 5% graphite) interacted with natural water collected from Josef Underground Educational Facility (UEF) Czech Republic, and four different types of artificial groundwater enriched in K+ and/or Mg2+. The experimental material was prepared in the form of (1) highly compacted samples, (2) dispersion of bentonites (both at temperature of 95 degrees C), (3) drill holefilling during in situ tests at the Josef UEF (at ordinary temperature), and (4) common batch laboratory experiments (at 20 degrees C and at 80-90 degrees C). Partial samples were extracted after 3, 6, 12, and/or 18 months of interaction in the first three set-ups, and after 1 week, 2 weeks, 1 month, 2 months, 3 months, 4 months, 5 months, 7 months, 10 months, and 12 months in the batch experiment. Phase composition and its potential changes were evaluated by X-ray diffraction. In the f
