Modern Materials and Methods for Restoration of White Stone Structures of the XII Century on the Example of the Golden Gate in Vladimir

Abstract

AbstractModern building materials and restoration techniques can extend the life of architectural monuments of any age, including ancient Russian architecture, which spans several centuries from the XII to the XIX centuries. One of the most striking examples of white-stone structures of that time is the Golden Gate, an architectural monument located on the territory of the Vladimir region in the city of Vladimir. The activity of living organisms causes the destruction of architectural monuments. The possibility of studying micromycetes of building materials of the Golden Gate is investigated. Samples of white stone, plaster and masonry mortars were taken in different parts of the monument to study their mycological state. In the course of the work, surface biocells were found that in-crease resistance to fungicides and thus resemble the mechanism of metal destruction (corrosion). Studies of the physical and mechanical properties of the masonry material of the Golden Gate showed that they retained strength in the range of 18–23 MPa. The study of the microstructure indicates a high porosity of the white stone. Mycological studies made it possible to identify the presence and deter-mine the dominant type of fungal lesions. Based on the results of the study, methods for restoring damaged areas are proposed in order to avoid their destruction in the future.KeywordsLimestoneStrengthTenacityMycologyRestoration
