Development of transient permeability theory and apparatus for measurements of cementitious materials Roy, DM et al
Publication details: Washington DC Strategic Highway Research Program, 1993; SHRP-C-627, Description: 30 sSubject(s): Online resources: Bibl.nr: VTI P1408:627Location: Abstract: A permeability apparatus was designed and constructed that would allow a rapid and accurate measurement of water transport in concrete. The test specimen acts as a permeable membrane between the two pressurized, large-volume reservoirs. Very rapid measurements are possible for specimens possessing permeabilities on the order of a microdarcy to a nanodarcy. In order to measure permeabilities below a nanodarcy, however, the problems of establishing pressure equilibration throughout the test specimen becomes more difficult.Holdings: VTI P1408:627
