The study shows the analysis of the various Roman mortars in the survival structure of the Danube Bridge in Drobeta-Turnu Severin, Romania, which is particularly relevant, and the results provided will help clarify the technology used for its construction through spectral, XRD and thermoanalytic techniques. It is intended to establish similarities or differences between the studied subjects. This paper highlights the complementary nature of the various techniques: XRD for the identification of major crystalline phases, FTIR for a more detailed evaluation of the composition comprising non-crystalline and TGA phase for the quantitative determination of volatile phases (especially CO2 and H2O).
