This research investigates the incorporation of aluminum and EFACO as strategic substitutions for metakaolin in potassium-based geopolymers. The primary objective is to assess the effects of these substitutions on the geopolymer structure, while maintaining a stable Al:Si:K:H₂O ratio. The focus is on compacting aluminum content within the geopolymer matrix while preserving the ratio's stability. Comprehensive analyses will provide insights into the structural, thermal, compositional, and environmental aspects of the modified geopolymers. The comparative analysis with the original geopolymer results aims to elucidate the impacts of these substitutions, contributing valuable information to the understanding of tailored geopolymer formulations.
