Together with about 1180 million tons of hot metal (2017) about 380 million tons of blast furnace slag are produced yearly worldwide. Most of it (about 280 million tons) is quenched forming the glassy granulated blast furnace slag (GBS). For more than 130 years, this by-product is used as a clinker substitute in cement and concrete. Many approaches exist to …
