As these materials are relatively new, their durability and long-term performance need to be evaluated. Wet-dry conditions may occur in many applications where bentonite liners are in use. In this study, two amended materials, the MultiSwellable bentonite and a DPH (Dense Prehydrated) GCL were subjected to simulated wet-dry ageing. Distilled water (DW) and natural seawater (NSW) were used as permeant liquids. After five wet-dry cycles, the hydraulic conductivity of both materials increased by two to three orders of magnitude. Unhealed desiccation cracks were identified as responsible for the increase in permeability. Conversely, wet-dry ageing in DW did not impact significantly the permeability of the DPH GCL. For both materials, post-test swell index and XRD diffraction indicated a loss of the chemical amendment, likely solubilised and/or eluted during the wet phases. The results point out that further investigation is necessary to fully address the permanence of swelling and permeability performances of these amended clays after long-term field service. Adequate measures are recommended to prevent or limit desiccation damage for use in applications where aggressive inorganic permeant liquids (e.g., NSW) are present.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effect of wet-and-dry ageing in seawater on the swelling properties and hydraulic conductivity of two amended bentonites","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Bentonite; Amendment; Polymers; Swelling; Hydraulic conductivity;Ageing; Desiccation","OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2019-07-10","DateCreate":"2018-05-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000405048000005","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.clay.2016.10.031"},"refs":null,"anarec":{"AnaID":295638,"PubliDate":2017,"Pagination":"40-51","XtraPublOfAnaID":null,"ISBN":null,"Volume":"142","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":258828,"SerRR":"Applied Clay Science.
