Ground granulated blast-furnace slag - Wikipedia
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing ...
A review on lead slag generation, characteristics, …
The compressive strength of concrete prepared from lead slag was superior to that of ordinary concrete. In addition, concrete containing lead slag absorbed gamma radiation more, which made it different from ordinary concrete. Saikia et al. (2012, 2008) used lead slag to replace 25–35% of the fine aggregate in the preparation of the cement mortar.
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.
