Alkaline solutions, typically composed of sodium or potassium hydroxides and silicates, play a pivotal role in the production of alkali-activated materials (AAMs), providing an alternative to traditional Portland cement in concrete applications. These solutions are key to triggering the chemical reactions necessary to form a hardened binder from aluminosilicate precursors such as fly ash, slag, or metakaolin. The use of alkaline solutions in concrete contributes to enhanced durability and resistance to environmental stresses, making it highly suitable for construction in areas facing severe environmental conditions like chemical exposures, extreme temperatures, and high moisture levels.
