The ability to replicate and generalize the results of applying practical methods using laboratory methods on the statistical population makes researchers more confident in analyzing the results of objective experiments to achieve reality. However, access to scientific and standard laboratory methods is one of the essential requirements of experimental techniqes that can be employed to accurately measure and evaluate the various physical, chemical, and mechanical properties of historical and cultural samples. The purpose of this study is to find a standard test that can use to measure the permeability and insulation properties of materials used in historical buildings against moisture. To achieve this goal, for the first time, falling head method was used to measure the permeability and insulation of traditional and ancient Kahgel plaster against moisture in historical buildings and architectural heritage. The samples of Kahgel plaster improved with different additives were compared to the typical Kahgel plaster samples as a control sample. Results of the study showed that using the laboratory method, reconstructed the conditions and behavior of water during adsorption and penetration into historical samples materials and represent their actual performance against moisture and rainfall. Therefore, it is possible to measure their permeability and insulating properties of earthen materials against water ‎quantitatively‏ ‏in saturated conditions with this method. }, URL = {http://jra-tabriziau.ir/article-1-304-en.html}, eprint = {http://jra-tabriziau.ir/article-1-304-en.pdf}, journal = {Journal of Research on Archaeometry}, doi = {10.52547/jra.7.2.36}, year = {2021} }
