Abstract
Nuclear Magnetic Resonance was employed to obtain information on the pore filling during the absorption process. A porous carbonate stone, largely employed for buildings and mainly outdoor decorations was studied during water absorption by capillary rise, and filled pores radii were evaluated by comparison between experimental and theoretical parametric magnetization decay curves. Non mono-exponential T-2 allowed spin populations to be split among the associated different relaxation times. (C) 2003 Elsevier Science Inc. All rights reserved.File in questo prodotto:
