MOISTURE CONDENSATION IN MASONRY WALLS OF ARCHITECTURAL MONUMENTS UNDER HUMID CLIMATE

Abstract

The need to save cultural heritage for future generations makes the task of predicting the moisture of masonry walls of architectural monuments urgent. The average monthly values of climatic parameters required for calculation have been clarified. Despite the absence of moisture condensation under the specified boundary conditions, an increase in the sorption humidity of building materials was detected. The boundary of the layer of temperature and heat flux fluctuations in masonry was determined. Increasing the humidity of materials located in this layer is dangerous. The calculation demonstrates that the plane of maximum humidification is located in this layer. This means that the joint of the brickwork and the outer plaster layer is subject to thermal risk. Further studies are related to the need to clarify the thermal characteristics of the enclosing structures of architectural monuments based on dynamic modeling of complex heat and mass transfer processes under complex climatic impacts, including taking into account humidification by oblique rains.
