“…Analysis conditions on an ARLX'TRA diffraction system are the following: interval -5-65°; speed: 5-6 degrees / min; voltage -40 kW; current -30 mA. The interpretation of diffraction patterns was carried out using appropriate methods, by comparison with similar studies, as well as using international databases [11,12]. Sample preparation for X-ray phase analysis was carried out by soft destruction of samples from which a fraction less than 0.08 mm was extracted, i.e.…”

The paper describes the process of recrystallization of portlandite of limestone mortar in calcite. The degree of crystallinity of calcite in limestone mortar of some medieval objects of the north of the Byzantine oecumene is shown through the example of Abkhazia and calcite in natural limestone and marble. The work provides a comparative analysis of the calcite crystallinity and the estimated age of the building objects according to historical and architectural data. It is proven that the higher the calcite crystallinity is the elder the lime mortar and, accordingly, the architectural object is.
