vastdamp
Vastdamp is a term used in discussions of moisture transfer within porous media to denote a hypothetical state in which moisture becomes highly persistent within a material. In this regime, capillary retention and interconnected pore pathways create large-scale damp conditions that are slow to dry under typical conditioning or drying processes.
The word vastdamp combines "vast" (extensive) with "damp" (moisture). It is a neologism that has appeared in
Vastdamp is described as arising when a porous medium exhibits strong capillary action, high surface area,
Characterization approaches include gravimetric moisture content, relative humidity profiling, electrical impedance spectroscopy, and pore-network modeling. Experimental
Vastdamp is used to explain stubborn damp spots in buildings, persistent soil moisture pockets, and materials
