The NE slopes of the Palatine and the Colosseum valley area have been the place of a long archaeological research; here the continuous urban development produced an overlap of architectural complexes distributed over time. The huge amount of archeological documentation elaborated by the research is managed by a data management system. For ancient walls analysis we have introduced the use of image-based-modeling photogrammetry in order to create a very detailed 3D documentation linked to a DBMS dedicated to ancient structural features. Through this methodology we can evaluate specific aspects...

Many papers have been written about geopolymers and their application, but only few of them report about the recipe to obtain suitable product for Cultural Heritage application. As regards to the production costs of geopolymers, we realized that these are not, now, comparable with those of cement Portland mortars, but the possibility of obtaining products for specific applications, makes the geopolymers suitable for specialist uses in the field of Cultural Heritage despite their cost. Starting from a simple metakaolin-based geopolymer we would try to find the right ingredients and proportion...

The sandstones of the Macigno Formation have been widely used in Tuscany as a building material since Roman times and even earlier by the Etruscans. In this work, we focus on the Macigno sandstone of the Monti d Oltre Serchio, on its physical properties and on its chemical, mineralogical and petrographic characteristics.

The sandstones belonging to the flysch-like deposits of the Macigno Formation are nearly the most used stones as a building material in north-western Tuscany. From prehistoric times to date, this stone has been employed to produce a wide variety of stone structures: prehistoric statue-stele, medieval monumental churches, railway infrastructures, town paving and civil buildings. The wide use of Macigno sandstones is responsible for the typical appearance of most towns and villages in north-western Tuscany; in fact, they show the grey to grey-yellowish colour of this stone, which lends them a...

Thermal decay may be one of the causes of monzogranite deterioration. In this work, we study the chemical, mineralogical and petrographic characteristics and the physical properties of the monzogranite of Elba Island as a building material, to better understand the main effects of the degradation caused by artificial thermal cycles on this rock.

During restoring operations of ancient buildings, datable between 1 th and 16 th century, in the city of Ravenna samples of mortars from different archaeological sites has been collected by the Superintendence for Archaeological Heritage of Emilia Romagna. Mineralogical and chemical analyses of these samples allowed to characterize mortars composition, comparing their features in order to highlight changes in construction technologies and chronological discrimination, by defining raw materials used and establishing their places of origin. In particular, mortars from: the Roman age San...

Acqua alta (high water) is a natural phenomenon that generally occurs in the city of Venice (Italy) in autumn and springtime, when a combination of astronomical tide, strong south wind (scirocco) and seiche can cause a large water inflow into the Venetian lagoon. The consequences of these events are the overflowing of the canals and flooding of the pedestrian walkways, leading to the degradation of the stone buildings over time. With the aim to better understand the effects of high water and how to take action for preserving the cultural heritage of Venice, thirty samples of five varieties...

In maritime archaeology, acoustic remote sensing technology has traditionally been used to locate and document inundated archaeological sites and shipwrecks. These methods are constantly evolving as technology advances, allowing for detailed spatial investigation and interpretation of submerged archaeological features. In the last decade, the advent of ultra-high resolution sonars has enabled to solve the three-dimensional (3-D) shape of submerged objects providing a valuable tool for recognizing and describing archaeological resources at the seabed. Remote sensing for seabed archaeology...

The impact of the Great War militarization processes has transformed most of Europe s territories, creating a meaningful warscape both in a material and cultural way. As a result of the inevitable post-war landscape transformations, the dense networks of military buildings designed for the war, as well as the traces of destruction, have been reabsorbed in the dynamics of landscape transformation, and today they remain almost exclusively as isolated fragments and, especially with regard to field fortifications, often barely recognizable. The need to recover a systemic look to give strength to...

A multidisciplinary project is being carried out by an Italian-Montenegrin team in the Roman town of Doclea in Montenegro. Applying a multi- and interdisciplinary approach and multiscalar analysis to the site and its surrounding territory, it has been possible to identify traces of the decumanus maximus, not only in the public centre of the city, where the main road was partially already excavated, but also outside the walls of the town, even into the suburbs of the capital of Montenegro, Podgorica.
