  Preparation and hydration process of copper slag …

  2024329 · Abstract Replacement of cement by solid wastes is an effective method to utilize secondary resources and reduce CO 2 emissions. In this study, copper slag (CS) and granulated blast furnace slag (GBFS) were used to replace cement to address the low activity of CS, which limits its large-scale utilization. The dissolution characteristics, …
