Capillary absorption of water and n-decane by autoclaved aerated concrete
Ioannou, Ioannis; Hamilton, Andrea; Hall, Christopher (2008)An autoclaved aerated concrete was one of three construction materials used in the round-robin study of hygral properties carried out in the European Commission funded Heat, Air and Moisture Standards Development [HAMSTAD] ...

Direct measurement of the wetting front capillary pressure in a clay brick ceramic
Ioannou, Ioannis; Hall, Christopher; Wilson, Moira A.; Hoff, William D.; Carter, Margaret A. (2003)The absorption of a liquid into a rectangular bar of an initially dry porous material that is sealed on all surfaces except the inflow face is analysed in terms of Sharp Front theory. Sharp Front models are developed for ...

On the role of organic adlayers in the anomalous water sorptivity of Lépine limestone
Ioannou, Ioannis; Hoff, William D.; Hall, Christopher (2004)Sorptivity data are reported for the capillary absorption of water, ethanol, propan-2-ol, and n-heptane by the calcitic limestone Lépine (Lavoux à grain). The data confirm that the water sorptivity is anomalously low, an ...

Synchrotron radiation energy-dispersive X-ray diffraction analysis of salt distribution in Lepine limestone
Ioannou, Ioannis; Hall, Christopher; Hoff, William D.; Pugsley, Victoria A.; Jacques, Simon D. M. (2005)We describe an analytical application of synchrotron radiation energy-dispersive diffraction tomography to map the distribution of crystalline sodium sulfate deposited by evaporation from solution within a building limestone.
