CONDENSATION HUMIDIFICATION OF STONE WALLS OF ARCHITECTURAL MONUMENTS IN HUMID CLIMATE CONDITIONS

Abstract

The need to preserve cultural heritage for future generations makes it crucial to predict the moisture conditions of stone walls of architectural monuments. The average monthly values ​​of climatic parameters required for the calculations have been refined. Despite the absence of moisture condensation under the given boundary conditions, an increase in the sorption moisture content of materials has been detected. The boundary of the layer of sharp temperature fluctuations and heat flow has been determined. Increased moisture content of materials located within the layer of sharp fluctuations is dangerous. Calculations have established that the plane of maximum moisture content is located within the layer of sharp fluctuations. This means that the junction of the brickwork and the external plaster layer is subject to thermal risk. Further research is needed to refine the thermal characteristics of the enclosing structures of architectural monuments based on dynamic modeling of complex heat and mass transfer processes under complex climatic influences, including taking into account moisture from slanting rain.
