Steel Slag an overview | ScienceDirect Topics

Carlos Thomas, Francisco Agrela, in New Trends in Eco-efficient and Recycled Concrete, 2019. 7.1.2 Types and classification of steel slags. Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process.
