Abstract :In this study, physicochemical, petrographic and mechanical properties of original lime mortars from a Roman Period basilica in Amasra dated to the 1 st or 2 nd centuries are examined. The study of mortar samples has been performed through polarising and stereo microscope observations, mineralogical (XRD) analyses, chemical (ICP-ES), physical and mechanical analyses. The micro structure and semi-quantitative chemical composition of the binding media and aggregate phases were determined by Scanning Electron Microscope with Energy Dispersive (SEM-EDS) analysis. This mortar possessed its hydraulic characteristic is due to the addition of volcanic rock with pozzolanic nature. Mechanical tests revealed that the average compressive strength of mortars is 6,1 N/mm 2 and flexural strength is about 3,3 N/mm 2 . Pull-off tests for determining the adhesion properties proved that a good adhesion is established between mortar and andesite stone owing to its pozzolanic nature.Keywords : Basilica, lime mortar, physicochemical- mechanical characterization, andesite, adherence
