Cinetica di assorbimento dell'acqua tramite NMR imaging per la valutazione della efficacia di trattamenti idrorepellenti

    Research output: Contribution to conferenceOther


    [automatically translated] The effectiveness of the treatments normally used to protect and / or consolidating stone materials may be evaluated using the imaging technique in nuclear magnetic resonance imaging (MRI), which allows to study in a quantitative way, non-invasive, non-destructive, the kinetics of capillary absorption water. In homogeneous samples (Lecce Stone) forms a front plate (with a sharp discontinuity at the scale of measurement) and the MRI technique allows to follow the kinetics since it allows to measure, as a function of time, the height reached by that front in any internal cross section of the sample. They are compared to the results obtained on the same litotype using two different water-repellent products. the results are interpreted in the light of the washburn model for capillary absorption,
