Abstract: The present thesis examines the grand staircase (1771) of the castle of Harmannsdorf (Lower Austria),
made of zogelsdorfer calcarenite. A material-and-condition survey indicated that the main damage
phenomena of structural damage is caused by repeated freeze-and-thaw cycles. Therefore the
main emphasis during the elaboration of a consevation concept was put on reconstruction mortars
for porous limestones exposed to freezing weather conditions. Test series shall indicate the waterspecific
properties as well as the frost resistence of different mortars that have already been used
successfully in practice. The results show differences between utilised materials by themselves as
well as in interaction with zogelsdorfer calcarenite and illustrate the importance of tailoring materials
to individual objects.


Keywords: Zogelsdorfer limestone, reconstruction materials, frost-thaw-cycle-caused damages, baroque garden
