Abstract

The main objective of this study is to evaluate the opportunities offered by nanotechnologies to the production of innovative mortars with enhanced performances for the reconfiguration of walls ridges in the archaeological field. In particular, an already existing additive, based on silica nano-particles in aqueous solution, was tested mixing it in varying percentages to a hydraulic lime mortar and pozzolana. The following tests were carried out on different samples: resistance to bending and compression, adhesion to the surface, water absorption coefficient through capillarity, accelerated ageing test using salt mist. In the final stage, some comparative considerations among the different mortars were deducted, offering several possibilities for the adoption of mortars with nano-additives even in the conservation of artefacts of great historical and artistic value such as the ones constituting the archaeological heritage.
