Adding to the complexity, the church houses important murals from the 14th to the 18th century that are also affected. To assess the situation and provide advice, both moisture and salt contents were analysed. The actual and hygroscopic moisture contents were determined gravimetrically, and the quantification of the ions was carried out by ion chromatography. The results show extreme concentrations of moisture and salts, with salt contents, excluding gypsum, up to 17 wt.%, containing, besides sodium carbonate, mainly sodium chloride and sodium sulfate and in lower quantities also potassium chloride and potassium nitrate. The results show extreme concentrations of moisture and salts. The values of the ion mixtures were used to model the behaviour of the salts in changing climatic conditions with ECOS/RUNSALT. Furthermore, the theoretically determined crystalli sation behaviour of several salt solutions was further investigated within a micro-climate chamber at 95 %RH and Raman spectroscopy. At this RH gypsum and gorgeyite formed in the salt solution derived from the plaster. The results led to the conclusion that once rising damp is stopped and the RH is maintained below 60 %, the main phase transitions of the salt mixtures could be prevented, thus minimizing future salt damage to the masonry and murals. }, key = {SWBSS 2021}, url = {https://predict.kikirpa.be/wp-content/uploads/2021/12/SWBSS2021_Procedings.pdf }, author = {Crevals, V. and Godts, S. and Desarnaud, J.} }
