Abstract: In this study, chemical, mineralogical and hydraulic characteristics of binders of mortars,
composed of fine siliceous aggregates and carbonated lime in some ancient Roman
buildings, located Xanthos (Antalya), Patara (Antalya) and Tlos (Muğla) in Southern Turkey
were investigated. Mineralogical compositions of binders were determined with X-Ray
Diffractometer (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) analysis. Chemical
compositions and microstructures were determined with a Scanning Electron Microscope
Coupled with X-Ray Energy Dispersive Spectrometry (SEM-EDS). Hydraulic properties of
binders were identified by determining the weight losses between 200-600°C and 600-900°C
by Thermogravimetric Analysis (TGA). The pozzolanic activity of the fine aggregates was
determined by measuring the differences in electrical conductivity. Analysis results showed
that binders of Roman mortars are composed of lime and pozzolanic fine aggregates. Due to
the use of pozzolanic fine siliceous aggregates, mortars are hydraulic.
