Moisture dynamics in building sandstone: implications for transport and accumulation of salts

D. McAllister, S. McCabe, S. Srinivasan, B. J. Smith & P. A. Warke
Moisture is an important control on processes of stone decay. Future climate projectionssuggest an increasing seasonality in precipitation in parts of northwest United Kingdom, with10-20 % increases in winter rainfall over the next half century. These changes will invariablybe reflected in stone moisture dynamics. Results show an outer stone layer sensitive toenvironmental moisture cycling, that when subjected to prolonged periods of rainfall (withimbibition exceeding evaporative loss) allows moisture penetration to depths of 25 cm after...
