Özet

Over time, the carbonated components of lime-based mortars dissolve and recrystallise, inducing calcite cementation in the resulting micro-cracks and pores, favouring self-healing capacity. In such types of mortars, the binder may originally contain gypsum, or, on the other hand, dissolution and precipitation processes of compounds from different sources (soil, construction materials or airborne particles) may derive in the formation of new saline minerals. The uptake of such components may interfere with chemical and physical analysis, hindering the interpretation of the data needed to determine the identification, provenance of raw materials, formulation, and production processes of mortars, carried out in archaeometric investigations.
