Slag Content Governs Compressive Strength of Ambient-Cured Alkali-Activated Mortars: An Experimental and Ensemble Machine Learning Study
Alkali-activated materials are a sustainable alternative to Portland cement, yet the relative importance of activator and precursor parameters under ambient curing is unquantified, and literature-trained models are rarely validated against independent mixtures. Twelve fly ash–GGBS mortars were prepared in a 2 × 2 × 3 f...
