The technological factors required to improve the operational properties of granulated metallurgical slags demanded in the building industry have been analyzed. In order to satisfy these factors, a new technology for hydro-vacuum granulation of slag melts (HVG) has been developed. It is shown that the main advantage of the proposed HVG This paper compares and studies the particle morphology, particle size distribution (PSD) characteristics, powder characteristics and hydration characteristics of ground granulated blast furnace slag prepared by a ball mill and a vertical roller mill. Both types of slag particles are found to comply with the Rosin–Rammler–Bennett (RRB) Study on the particle morphology, powder ScienceDirect

Alkali-activated copper and nickel slag cementitious materials (ACNCMs) are composite cementitious materials with CNS (copper and nickel slag) as the main materials and GGBFS (ground-granulated blast-furnace slag) as a mineral admixture. In this paper, the activity indexes of CNS with different grinding times were studied using CNS The possibility of obtaining gray, pink, light brown, crimson, olive green pigments based on blast-furnace slag is substantiated. Blast-furnace slag was studied using X-ray analysis, energy-dispersive X-ray microanalysis, and digital electronic microscope. The high efficiency of the low-temperature process for obtaining pigments is shown. It Utilization of Furnace Slag for Pigments Production
