Particle-Size-Fractionated Coal Gasification Slag as a Supplementary Cementitious Material: Hydration Products, Microstructure Evolution, and Mechanical Performance via Classified Grinding

To promote the high-value utilization of coal gasification slag (CGS) resources and mitigate the environmental issues caused by its accumulation, CGS was separated into five fractions by particle size (2.36–4.75 mm, 1.18–2.36 mm, 0.60–1.18 mm, 0.30–0.60 mm, and 0.15–0.30 mm) and subsequently ground into CGS powders (CG...
