Fig. 3

a Photograph showing the condition of the lab-cast mortar after 142 freeze-thaw cycles under the submersion of a 25 wt.% CaCl2 solution. Scale in millimeters. b Reflected light photomicrograph (RLP) of the polished surface of the lab-cast mortar. White square and red curve indicate the original size and the remaining intact zone of the sample, respectively. The yellow green color in (b) indicates the epoxied damage zone. c and d Photographs showing the condition of the lab-cast paste after 51 freeze-thaw cycles under the submersion of a 25 wt.% CaCl2 solution. Note the delamination near the exposure surfaces
