Abstract

Plaster and mortar samples have been collected from buildings in Northern Tyrol/Austria and Southern Tyrol/Italy representing the periods from Romanesque to Baroque. The mineralogical composition and the textures of the binding material of these plasters and mortars were studied. One of the most important results is the discovery of dolomitic lime mortars at most localities investigated. Magnesite, hydromagnesite and brucite could be identified using a combination of XRD, DTA/TG, EMPA, Raman spectroscopy. In addition X-ray mapping and DTA/TG analysis indicate the presence of amorphous or poorly crystalline magnesium phases.
