Abstract

Permanently changing temperature and moisture gradients, sometimes in conjunction with frost and ice formation as well as partially arising crystallisation processes of solved salts in the building sand- stones lead to a weakening of the sandstone material. For the description of the deterioration process due to these main actions, which cause primarily a gradual failure of the grain bonding proceeding from the surface to inner parts of the cross section, an appropriate model for the weathering of sandstone is presently being de- veloped.
