Project objective

Cultural heritage materials can be the starting point for the experimentation of binding materials to be used in the field of constructions. It is the case of hydraulic mortars from ancient Roman aqueducts. In fact, the preliminary characterization of these mortars revealed the occurrence of an amorphous binder, which composition is comparable to a calcium-sodium/potassium aluminosilicate hydrate (C-(N,K)-A-S-H). However, the factors that allowed the formation of this peculiar binder, not previously attested in other ancient structures, are still unknown. The aim of DAPHNE is to elucidate the chemical composition and physical structure of amorphous/nanocrystalline binders in ancient Roman mortars and understand the processes that lead to their formation using geochemical experimentation. In the future, the assessment of the properties of the amorphous binder can verify its employability as sustainable and durable material for cement industry applications, chasing the goals of the 2030 Agenda for Sustainable Development.
