Pore expansion upon drying
Webauthors hypothesize that upon drying, a high capillary force forms in the materials of fine pore structures like AAS (Collins & Sanjayan, 2000; Neto et al., 2008). This assumption has not been verified though, as drying shrinkage tests under a broad range of relative humilities (e.g. from 30% RH to 100% RH) have not yet been conducted.
