Geopolymer-based Coating Material for Metal Substrate

Coating is an applied layer on the substrate to enhance properties of the substrate. Geopolymer is produced through geopolymerization between alumina-silicate and alkaline solutions and has a great potential to be utilized as geopolymer-based coating material. The aim of this study is to investig...
