Slag Aggregate - an overview ScienceDirect Topics

James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016 1.5.1.6 Slag. Slag aggregates are obtained by crushing of smelter slag or by special treatment of fire-liquid slag melt (molten slag aggregates). Currently there are many types of concrete that are developed and used in construction that include metallurgical slags both as a binding component and as fillers.
