Il consolidamento dei materiali moderni tra conservazione e sostituzione. Un problema di restauro o di manutenzione ordinaria?

The present paper is a critical reflection on the surface consolidation regarding the materials used in modern buildings with an acknowledged value of cultural heritage. The acknowledgment of the historical and artistic value of a modern building does not simply entail the necessity of operating according to the common standards of building maintenance but also the necessity of applying the preservation criteria. Consequently, it is important to develop an in-depth theoretical analysis of the criteria and methodologies for the conservation of modern buildings, in particular as regards surface consolidation. The following materials were analysed: finished concrete, ceramic coatings and plaster surfaces containing asbestos. The paper aims to understand whether the conservation principles applied to historic buildings are suitable for reproducible and serial materials which are close to our technologies.
