Investigation of mechanical activation of steelmaking slag and obtaining fine filler

Abstract

The article presents the results of the mechanical activation of steel-smelting slag affecting the properties of the gypsum composition. As a result of the study, parameters were identified that characterize the reactivity of the slag during mechanical activation. It was established that the increase in the number of Bronsted active adsorption centers on the surface of the formed powders is responsible for their reactivity. However, the maximum increase in surface activity leads to a large percentage of residue on the sieve. Also, polynomial models were obtained that adequately describe the entire process of mechanical activation of waste from metallurgical production.
