In another study, Jenni et al. stained MHEC with a fluorescent dye and visualized and quantified the migration of MHEC through the capillaries of mortars.

In a later publication from this group they state that the dissolved CE is transported downwards through the capillary pores, but accumulates at the contact layer and substrate surface, which act as micro-filters [19].
