Correlation of hollow and solid cylinder dynamic pressurization tests for measuring permeability / Christopher A. Jones in Cement and concrete research, Vol. 39 N° 4 (Avril 2009)  

Public ISBD [article]  inCement and concrete research > Vol. 39 N° 4 (Avril 2009) . - pp. 345–352 Titre : Correlation of hollow and solid cylinder dynamic pressurization tests for measuring permeability Type de document : texte imprimé Auteurs : Christopher A. Jones, Auteur ; Zachary C. Grasley, Auteur Année de publication : 2009 Article en page(s) : pp. 345–352 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Degradation  Durability  Permeability  Transport properties  Poromechanics Résumé : An experimental apparatus and analytical derivation are developed for quantifying the permeability of cementitious materials using dynamic pressurization of a hollow cylinder. Experimental results from the newly developed hollow dynamic pressurization technique for measuring permeability are then compared to results obtained using the solid dynamic pressurization test. The measured permeabilities obtained from testing Vycor® glass and hardened cement paste indicate close agreement between the two test methods, which supports the validation of the hollow dynamic pressurization test as an accurate and repeatable method for measuring the permeability of cementitious materials. Three different pore fluids with widely varying viscosities were tested, each yielding equivalent intrinsic permeabilities. Additionally, the permeability values from this study agree reasonably well with relevant values presented in the recent literature.
