Discretization of the Water Uptake Process of Na-Montmorillonite Undergoing Atmospheric Stress: XRD Modeling Approach

Figure 3

Schematic representation of the structure model used to fit the experimental XRD pattern in the case of the unstressed sample along the sorption process. Relative proportions, expressed in wt.%, of the three elementary mixed-layer structure (MLS) contributions are plotted on the y-axis, whereas their compositions (relative proportions of the different layer types) are plotted on the x-axis.
