Performance evaluation of fly-ash and silica-fume based geopolymer concrete at different alkaline molarities with machine learning-based strength prediction

Abstract The high environmental impact of conventional Portland cement has driven the need for sustainable alternative binders with improved performance characteristics. Geopolymer concrete (GPC), particularly using industrial by-products such as fly ash and silica fume, has emerged as a promising s...
