Recently, polyelectrolyte (PE) hydrogel has attracted attention among tough hydrogels. This hydrogel possesses the physical ionic crosslinking of cation and anionic monomers with a reversible network structure. It features strong mechanical properties, biocompatibility, self-healing property, and adhesion to tissues with positive and negative charges. Previous studies in our group reported that PE hydrogels also adhere to concrete structures. It was also confirmed that this mechanism is an electrostatic bonding between PE hydrogel and concrete material. In this study, we investigated the adhesion behavior in concrete mixed with two environmentally friendly additives. Changes in adhesion properties according to the composition of the additives were shown. In addition, long-term stability of the bonding system consisting of PE hydrogel and concrete under various salt conditions was studied. |
