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.

Effect of Ground Granulated Blast Furnace Slag
1 天前 This study was conducted to investigate the effect of ground granulated blast furnace slag on the structural performance of precast concrete beams, evaluating the flexural, shear and bonding performance by using the replacement ratio of the ground granulated blast furnace slag as a variable. The design strength of the concrete was set at 45 MPa in consideration of the characteristics of ...

In addition, 7.4 Mta of steelworks slag was produced. Fig. 9 shows the amounts recovered. It can be seen that only granulated blast furnace slag (GBFS) can be used as a cement additive. For ready-mixed concrete and other types of concrete, both normal blast furnace slag and steelworks slag are used with respective totals of 38.7 % and 20.3 %.
