Advanced investigation of water sorption isotherms measured on raw earth construction blocks

Abstract This study offers a detailed analysis of water sorption isotherms in raw earth materials, which are increasingly recognized as sustainable alternatives to traditional building materials. The water retention behavior of Compressed Earth Blocks (CEBs) was examined under steady-state conditions using sorption isotherms, which do not fully capture transient moisture buffering performance at the building scale. In this context, we focus on their ability to adsorb and desorb moisture as a mea
