This work reports a characterization of the possible effects that might affect the hydration properties of Mg-exchanged low-charge montmorillonite (SWy-2-Mg) when undergoes an external environmental solicitation. The latter was created by an alteration of relative humidity rates (i.e. RH%) over two hydration-dehydration cycles with different sequence. The study was mainly based on the X-ray diffraction profile modeling approach. Obtained results show strong hydration dependence as a function of the RH sequence. The interlayer configuration presents a heterogeneous hydration behavior which was systematically observed at different stages of both cycles. The interlayer water uptake process presents similar hysteresis characterized by fluctuations of interlayer water molecule abundances.
