Slag cement has good water retention, good plasticity, less bleeding, and good workability. It can inhibit the dissolution of heavy metals such as high-valent chromium in concrete. Reducing the heat of hydration is beneficial to prevent cracks caused by the internal temperature rise of mass concrete.

In 2016, the production of BF slag in the world was 430 Million tonnes; from that 66% of the total volume was GBF slag whereas 34% accounts for ACBF. The distribution of the production data of BF slag on an area wise is shown in Fig. 1. Globally, 32% of the total slag is produced in China (TMR, 2017), which is about 139 million tonnes.
