Valorization of diatomaceous earth as an alternative activator for pumice–based geopolymer concrete: Experimental and multiple linear regression modeling

Geopolymer cement (GC) is gaining attention as a sustainable alternative to Portland cement due to its lower CO₂ emissions. However, GC formations rely on sodium silicate, which is expensive, and its production has a high carbon footprint. The development of alternative silica an...
