Abstract

In this paper we deal with an experimental activity aimed to the characterization ofa compact local limestone, named Trani stone. Compact limestones are very commonmaterials used in the monumental and historic built heritage. In particular, withreference to the Apulian region (Southern Italy), they are the constituent stones of thenumerous Romanesque Cathedrals, as well as of many other important monuments suchas the UNESCO site of Castel del Monte. They have also been employed for thebuilding of the fortified towns and norman-swabian castles facing the sea. The studyreports mineralogical-petrographical and physical features, with particular reference tothe behaviour with respect to the water. Ultrasonic tests have also been performed asindirect tool for the qualification of the stone in dry and wet conditions. A superficialtreatment with photocatalytic titania (in water and alcoholic solution) has also beenapplied to the stone, in order to study the potential use of self-cleaning and antipollutionnanotitania coatings for stone surface protection; a preliminary assessment ofthe morphology and distribution of the titania films on the stone surface and relatedcolour changes has been carried out.
