Abstract | Coatings can extend the service life of concrete structures exposed to marine environments by inhibiting the intrusion of corrosive ions. In the present paper, the possibility of using geopolymer as an innovative inorganic coating for marine concrete protection was evaluated by 5 basic properties: setting time, permeability, anticorrosion and bond strength as well as volume stability. Fresh coat needed about 2h to finally set at 25°C. A compound geopolymer was developed by adding 10% granulated blast furnace slag (GBFS) in metakaolin as starting materials at the liquid/solid ratio of 0.60 ml/g. The presence of GBFS had a beneficial effect on reducing the permeability of the geopolymer. Although the strength development was |
