Physical Properties of Glass and the Requirements for
Weathering of float glass can be categorized into two stages: “Stage I”: Ion-exchange (leaching) of mobile alkali and alkaline-earth cations with H+/H3O+, formation of
Among the promising alternatives for improving waste valorisation of glass, alkali-activated materials (AAMs) emerge as a solution. Waste glasses can be employed both as aggregates and as precursors, with a focus on its application as the sole raw material for synthesis.
This suggests that the molecular mechanism of mild alkali-activated glasses is similar to glass corrosion. Due to the limited molarity, the alkaline solution does not allow for the complete dissolution of the glass used as raw material, but only affects the surface of the glass particles.
However, in mild alkaline solutions, glass components released are considered minimal compared to the surface hydration of powdered particles, a phenomenon that leads to the formation of hydroxyl groups through bond cleavage of strong bonds (Si–O–Si, Si–O–Al, and Si–O–B).
This comprehensive overview results in the following conclusions: Glass has the potential to serve as the sole raw material for alkaline activation, functioning independently of its chemical composition and the molarity of the alkaline solution.
