Comparison of the Saturated Salt Solution and the Dynamic Vapor Sorption techniques based on the measured sorption isotherm of barley straw
Résumé
9 For Heat, Air and Moisture modelling, one of the most crucial hygrothermal properties of porous 10 construction materials is the sorption isotherm. Current techniques for measuring the sorption 11 isotherm rely on the standardized Saturated Salt Solution (SSS) method which is known to be time 12 consuming. Recently, a device called Dynamic Vapor Sorption was applied on building materials 13 allowing faster measurements but limiting the mass and volume of the sample. As this technique is 14 not yet standardized, an experimental procedure was developed and validated on barley straw. 15 Results were also in good agreement with the measurements from the SSS technique. 16 17
