The gas relative permeability of a reference mortar and a concrete, which is used in the low and intermediate level waste storage center in Soulaines, has been measured. A method to measure water relative permeability of two concretes CEM I and CEM V, which will be used in the building of a underground disposal, has been proposed. But the difficulty of isolating the part due to the permeation in the unsaturated flow shows that the flow of capillarity is predominant in unsaturated flow. The capillary adsorption of concretes CEM I and CEM V has been measured. At the same level of water saturation, the gas relative permeability of sample pre-treated by capillary adsorption is less than that of sample pre-treated by adsorption in relative humidity. A double retention model has been proposed and it can describe the sorption isotherm of two concretes CEM I and CEM V. The curves of gas and water relative permeability are deducted. The hysteresis of sorption leads to the hysteresis of water relative permeability while there is not notable hysteresis of gas relative permeability. With double-retention model and water relative permeability expression, we can simulate sorption process under relative humidity by using a proper value of water intrinsic permeability which is in the domain of measured values """ ; dct:identifier "NNT: 2011ECLI0018" ; dct:issued "2026-05-24T14:34:27.855473"^^xsd:dateTime ; dct:language "fr" ; dct:modified "2026-05-24T14:34:27.855487"^^xsd:dateTime ; dct:publisher ; dct:title "Experimental study on gas and water relative permeability of cementitious materials and numerical simulation of water transport of concrete" ; dcat:contactPoint [ a vcard:Organization ; vcard:fn "CCSD" ] ; dcat:distribution ; dcat:keyword "beton", "capillarite", "capillarity", "concrete", "infoeu-reposemanticsdoctoralthesis", "permeabilite", "permeability", "simulation", "spiotherengineering-sciences-physicsother", "theses" ; dcat:landingPage . a dcat:Distribution ; dct:format "HTML" ; dct:issued "2026-05-24T14:34:27.877966"^^xsd:dateTime ; dct:modified "2026-05-24T14:34:27.816387"^^xsd:dateTime ; dct:title "Experimental study on gas and water relative permeability of cementitious materials and numerical simulation of water transport of concrete" ; dcat:accessURL . a foaf:Agent ; foaf:name "test_moissonnage_selune" . a foaf:Document .
