MALTE INNOVATIVE PER LA COPERTURA DELLE CRESTE MURARIE IN AMBITO ARCHEOLOGICO
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 …
MALTE INNOVATIVE IN AMBITO ARCHEOLOGICO
The aim of this study is the formulation of a special mortar with improved adhesion, elasticity, workability, water resistance compared to traditional mortars. This has been achieved thanks to the addition of nanostructured products able to influence the reaction of water with the hydraulic binder, in order to reduce the drying shrinkage and the subsequent micro-cracks, increasing the elasticity of the material and favoring the anchoring to the surface application. The study focused on laboratory testing of innovative mortars, based on a mixture of hydraulic lime, pozzolana and a nanostructured additive based on silica nanoparticles in aqueous solution. The physical and mechanical character…
