Samenvatting

Salt weathering is one of the major causes of deterioration of buildings and monuments. We have detd. the underlying moisture and ion transport within a representative building material by measuring the time evolution of NaCl satd. samples during one-sided drying with Magnetic Resonance Imaging. The obtained NaCl concn. profiles reflect the competition between advection to the surface and redistribution by diffusion. By representing the measured moisture and NaCl profiles in a so-called efflorescence pathway diagram (EPD) also information about the crystn. process is obtained. The pathways followed in the EPDs indicate that for historical objects in general crystn. at the surface cannot be avoided, when evapn. cannot be prevented.
