Abstract

In the framework of the European project “Desalination”, the Saint Philibert site has been selected as a field study to assess and compare the effectiveness of five desalination poultices after one application. These poultices were applied on two inner walls on the south side of the church. The decrease of salt concentration as well as the depth of desalination was taken into consideration in the definition of the effectiveness. This paper strongly underlines the close link between the effectiveness of desalination treatments and the properties of both stone and poultice materials. Analyses suggest that pore size distribution of the poultices should overlap pore size of the substrate for optimization of desalination efficiency. Moreover, size and arrangement of grains are probably important parameters to take into consideration when formulating poultices, as they directly influence the capillary suction of the solubilized salt solution.
