Strength and microstructural evaluation of sustainable geopolymer mortars using calcium carbonate sludge and fly ash as precursors

This study investigated the effects of alkaline activation on geopolymer mortars synthesized from fly ash and calcium carbonate sludge precursors. The research systematically examined key parameters including NaOH molarity (5 M, 10 M, 15 M), sodium silicate-to-sodium hydroxide ratio (0:100–90:10), f...
