Our simulations does not catch electrolyte intrusion in chabazite as shown in experiments which may be attributed to the absence of defects in our models of zeosil or even other phenomenon that are not taken into account using classical force field such as reactivity of water with zeolites. Nontheless, it was shown by in situ X-ray diffraction experiments on NaCl aqueous solutions intrusion in pure silica chabazite and LTA-type zeosil that only the water molecules penetrate firstly (or at low pressure) into the pores, and we will work henceforth within this hypothesis.
