The swelling pressures thus determined were compared with the reported experimental swelling pressures. The study revealed that, in general, at low compaction dry densities of the bentonites, the experimental swelling pressures are less than their theoretical counterparts, with the reverse trend at high compaction dry densities. Based on the reported experimental results for the three bentonites, relationships between the nondimensional midplane potential function, u, and the nondimensional distance function, Kd, were established. New equations for the swelling pressure were proposed on the basis of the diffuse double layer theory and the reported experimental data to compute swelling pressures of compacted bentonites. The suitability of the new equations was also verified with additionally reported experimental swelling pressures from three other bentonites (Kunigel V1, Kunigel, and bentonite S-2) that have been also proposed for use as barrier materials. Very good agreement was found in all the cases between the experimental swelling pressures and the swelling pressures obtained using the proposed equations. The use of the proposed equations is based on the weighted average valency of the cations present in bentonites, since the valency of the cations present has a significant influence on the swelling pressure.Key words: clays, compressibility, swelling pressure, expansive soils, chemical properties, radioactive waste disposal.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388844500345985","@type":"Researcher","foaf:name":[{"@value":"Snehasis Tripathy"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844500345984","@type":"Researcher","foaf:name":[{"@value":"Asuri Sridharan"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388844500345986","@type":"Researcher","foaf:name":[{"@value":"Tom Schanz"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00083674"},{"@type":"EISSN","@value":"12086010"}],"prism:publicationName":[{"@value":"Canadian Geotechnical Journal"}],"dc:publisher":[{"@value":"Canadian Science Publishing"}],"prism:publicationDate":"2004-06-01","prism:volume":"41","prism:number":"3","prism:startingPage":"437","prism:endingPage":"450"},"reviewed":"false","dc:rights":["http://www.nrcresearchpress.com/page/about/CorporateTextAndDataMining"],"url":[{"@id":"http://www.nrcresearchpress.com/doi/pdf/10.1139/t03-096"}],"createdAt":"2004-07-05","modifiedAt":"2021-06-24","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050008244166887424","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Fault weakening caused by smectite swelling"}]},{"@id":"https://cir.nii.ac.jp/crid/1050012570391214336","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Constitutive model for swelling properties of unsaturated bentonite buffer materials during saturation"}]},{"@id":"https://cir.nii.ac.jp/crid/1360294643751751552","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"A double structure model for hydro-mechano-chemical behavior of expansive soils based on the surface phenomena of mineral crystals"}]},{"@id":"https://cir.nii.ac.jp/crid/1360848657453422720","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Smectite swelling in the Miura–Boso accretionary prism: Possible cause for incipient décollement zone formation"}]},{"@id":"https://cir.nii.ac.jp/crid/1361412889695911168","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"A method for extending a general constitutive model to consider the electro‐chemo‐mechanical phenomena of mineral crystals in expansive soils"}]},{"@id":"https://cir.nii.ac.jp/crid/1390289687381580160","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Reversibility of micro and macrostructure in compacted bentonite under chemo-mechanical couplings"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1139/t03-096"},{"@type":"CROSSREF","@value":"10.1186/s40623-019-1108-5_references_DOI_XEiIu5zH9nZ312P1C6ofBb3wF0o"},{"@type":"CROSSREF","@value":"10.3208/jgssp.v09.cpeg021_references_DOI_XEiIu5zH9nZ312P1C6ofBb3wF0o"},{"@type":"CROSSREF","@value":"10.1016/j.enggeo.2021.106366_references_DOI_XEiIu5zH9nZ312P1C6ofBb3wF0o"},{"@type":"CROSSREF","@value":"10.1016/j.sandf.2022.101161_references_DOI_XEiIu5zH9nZ312P1C6ofBb3wF0o"},{"@type":"CROSSREF","@value":"10.1002/nag.3026_references_DOI_XEiIu5zH9nZ312P1C6ofBb3wF0o"},{"@type":"CROSSREF","@value":"10.1016/j.tecto.2010.08.008_references_DOI_XEiIu5zH9nZ312P1C6ofBb3wF0o"}]}
