Abstract
Samples of a soft calcareous sandstone taken from the wall were exposed under a porch with or without temperature control. Lowering the temperature increased water absorption but did not influence sulphate increase rate. In absence of rain or capillary rise sulphates provenience is only from atmosphere.
