The article describes the possible ways to modify the parameters of earth-based mortar used for the reconstruction of masonry structures on excavations located in the Black Sea area - archaeological site in Tyritake in Kerch on the Crimean Peninsula and Tanais near Rostov-on-Don in Russia. The structures we meet during these archaeological missions are irregular walls made of lime rock on earth-based mortar, which show a significant degree of disintegration due to the poor properties of the mortar and destructive atmospheric impacts. To carry out their reconstruction, it is necessary to select a mortar with appropriate parameters following conservation principles. Since earth-based mortar does not have sufficient characteristics, various possibilities for modification of its composition were considered, such as the addition of hydrated and hydraulic lime or cement. The compressive strength, adhesion, and durability parameters for unmodified and modified mortars were compared. Also, the issue of compatibility of the new reconstruction mortar with the existing stone material will be highlighted, which is crucial in the selection of material for the reconstruction of historic buildings.
