From mining wastes to mineral sources - investigating the REE-bearing occurrences in the Arburèse District (SW Sardinia)

In recent years, the search for possible sources of REE minerals in Europe involved numerous old mine areas with high volumes of mining wastes that may offer significant amounts of Critical Raw Materials (CRMs). In some cases, strong evidence of CRMs anomalous concentrations arises from environmental characterization of wastes, so that an interesting problem is that of finding their sources, i.e., the original CRMs - rich mineral phases in the residual ore. An excellent example is provide...

BIM based workflow for 4D construction planning

The studies conducted on Building Information Modeling methodology and its associated tools spotlight the related great improvement in managing the construction phase. This paper shows how BIM4D simulation can boost the accuracy of the temporal and economic forecast of the constructive intervention. This approach can reduce problems related to the incorrect interpretation of the work program because it is able to directly relate the information model with the work program in a single environm...

Numerical approches for soil-structure interaction in a historical industrial masonry building

Different numerical approaches were considered to investigate the possible causes of the structural damages detected in the masonry walls of an historical industrial building built at the beginning of the XX century in Italian Lombardia region; the building has a strategic role working as part of a drainage plant used for the reclamation of an extensive area close to the Po River. The structural analyses were performed with two different levels of complexity. In the first approach, structural...
