Abstract: Mortars made by lime and pozzolans were a standout amongst the most critical contribution
of Romans to the architectural history. Roman lime mortars have been exceptionally
renowned for their quality and durability which generally relied upon the resources utilized
in Roman domains. A comprehensive examination of this past technology leads us to better
conservation practice and more sustainable construction.
To have a broader perspective this research was carried out in different Roman provinces.
This paper aims at presenting the characteristics of Roman mortars from three
archaeological sites in Spain (Mérida), Egypt (Alexandria) and Turkey (Labraunda).
Characterization was carried out through polarized optical microscopy (POM), X-ray
diffraction (XRD), thermal analysis and differential scanning calorimetry (TGA-DSC), scanning
electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS), X-ray
fluorescence (XRF), Fourier Transform Infrared spectroscopy (FT-IR).
The central focus of the study is to understand the usefulness of the analytical methods
which give clue about the construction technology, selection of raw materials according to
the function and conservation state of mortars. We will also discuss to what extent we can
find answers concerning aggregates, natural and inorganic additives and their effect on
shrinkage, the manufacture of lime, the effects of environmental conditions and the
interaction between adjacent building materials.
