Abstract Coal Gasification slag, a solid waste produced during the process of coal gasification, has some characteristics such as a large storage vo-lume, high carbon content, weak cementitious reactivity, and heavy metal enrichment, and its large-scale and harmless utilization faces significant challenges. This paper systematically reviews the mineralogical properties of coal gasification slag and the mechanisms influencing its cementitious reactivity enhancement. The study shows that the highly polymerized aluminosilicate glass phase and residual carbon in coal gasification slag are the core factors limiting its reactivity. physical activation through mechanical grinding to destroy the crystal structure and increase the specific surface area, but the role of the effect is limited. chemical activation is mainly through the acid, alkali, salt, organic solvents to depolymerize the aluminosilicate network to release active ions (Al3+, Si4+, Ca2+), but requires precise control of hydration reaction pathways. Thermal activation removes residual carbon and reconstructs crystalline phases through high-temperature treatment, yet faces high energy consumption. Composite activation and bio-mineralization techniques demonstrate synergistic potential, but the current research is insufficient. In the future, it is necessary to develop low-carbon and high-efficiency multi-technology paths from the mineralogical properties of coal gasification slag, overcome bottlenecks in high-dosage applications, and provide theoretical foundations for high-value utilization of coal gasification slag as building mate-rials.
