Valorization of aplite in alkali-activated materials

Journal of Materials Science
AbstractGeopolymers belong to the broad family of alkali-activated materials that are considered to have much smaller carbon dioxide (CO2) footprint than traditional Portland cements. A wide range of metallurgical wastes are utilized as silicious sources to produce geopolymer components with a prospect of numerous applications in the construction field.
