Experimental selection of a repair and restoration composition of a solution based on hydraulic construction lime

Objective . This study presents the development and investigation of repair and restoration compositions based on hydraulic lime and white cement, as well as their physical and mechanical properties and chemical composition. Method. The work used an experimental method of destructive and non-destructive quality control of building materials and X-ray phase analysis to determine the mineralogical composition of the samples. Result. Physical and mechanical tests of the samples were carried out in order to select a restoration composition for the stone masonry of the walls of tower-type historical and cultural monuments. Conclusion . The developed repair and restoration compositions based on hydraulic lime and white cement have satisfactory physical and mechanical properties, which makes them promising for use in the restoration and reconstruction of cultural heritage sites. The results confirm the possibility of using these compositions in construction practice, which can contribute to the preservation of cultural heritage.
