Calcination Effects on 3D-Printed Phosphate-Activated Geopolymer Lattices: Structure, Strength, and Stability in Acidic Media
Phosphate-activated geopolymers (PAGPs), a class of acid-activated rather than alkali-activated binders, are promising monolithic materials, yet optimizing porosity while maintaining stability in highly acidic waters remains challenging. Here, a metakaolin–phosphoric acid geopolymer ink containing laponite and Pluronic...
