摘要：
The development of solid waste-derived activators for the preparation of alkali-activated systems is of great significance for further enhancing the environmental friendliness and sustainability of alkali-activated materials. In this review, the potential feasibility of applying solid waste-derived activators to prepare alkali-activated systems is explored. Through a discussion of alkali-activation mechanisms, the effect of activators on high-calcium and low-calcium systems is highlighted first. The properties and limitations of commonly used industrial-grade alkali activators are reviewed next. Finally, recent reports on waste-derived activators in alkaline activation systems are summarized, revealing the advantages and development trends of solid wastes with CaO, K2O/Na2O, and SiO2 as the main components of effective substitutes for alkaline industrial exciters.
