Organic-inorganic composition for stone masonry walls of ancient tower and necropolis buildings in the North Caucasus

Search works were performed based on archival and bibliographic research, which allowed us to get an idea of the monuments of archeology, history, and culture. For laboratory physical and physicomechanical studies, samples collection of the masonry wall solution was taken. Based on the conducted laboratory studies, a conclusion was made about the necessary grade strength of the masonry mortar of 25-75 kg/cm2 with the following physical and mechanical properties of the solution are as follows: average compressive strength-8.3 MPa; water absorption-11.7%; porosity-18.3%; volume weight-1.56 g / cm 3 .stress-related properties: average compression strength – 8.3 MPa; water absorption – 11.7%; porosity – 18.3%; volume weight – 1.56 g/cm 3 . The testing of new experimental compositions was performed in places accessible for observation and documented. Local inert, reinforcing, and binding materials were used to select the composition of the stone masonry solution for the walls of ancient tower and necropolis buildings. The research was carried out using existing methods, adjusted to take into account the peculiarities of the historical and cultural monuments under consideration. Based on the study results were developed organic-inorganic compositions of solutions of stone masonry walls of ancient tower and necropolis buildings in the North Caucasus.
