Abstract

In this study, the effects of two types of waste glasses on the performance of glass-ceramic artificial aggregates (AAs) were investigated to determine the contribution of the glass in the crystallization processes and provide theoretical support for the subsequent use of the solid wastes to prepare glass-ceramic-based AAs. The results showed that introducing glass mainly provided amorphous materials to facilitate crystallization and fluxing components to reduce liquid viscosity. The crystallization mechanism of the AAs was explained by understanding the SiO₂ characteristics and the liquid viscosity on the AAs properties. The results showed that amorphous SiO₂ and low viscosity were beneficial to the crystallization process, and the properties of [Si–O] significantly influenced the viscosity of the liquid phase. AAs prepared with multiple solid wastes were compared with pure muck AAs, and they showed higher strength with similar densities.
