a-d Reflected light photomicrographs of the polished surface of the damaged field mortar (a and b) and lab-cast mortar (c and d), respectively, showing horizontal cracks/microcracks at two different depths from the exposure surface. Zones in (a) and (c) are closer to the exposure surface. Yellow and red arrows indicate cracks/microcracks with and without secondary deposits, respectively. e Fresh delamination sheets in the damaged lab-cast paste. f Transparent secondary deposits on the surface of the delamination sheet in (e)
