Blast Furnace Slag an overview ScienceDirect Topics
2017-10-18 7.2.2 Blast-furnace slag BFS is a by-product obtained in the manufacture of pig iron in the blast furnace. It taps out from the blast furnace as a molten liquid at a temperature of 1400°C–1500°C and occurs either as a crystalline or granulated form depending on the treatment method for the molten liquid slag.

Activation of blast furnace slag by a new method
2009-8-1 Conclusions. Blast furnace slag is usually activated by mixing with Portland cement clinker. At very high pH values (> 13.0) corrosion of the slag particles is enhanced and the reaction of blast furnace slag is accelerated. Alternatively, the use of low pH values (11.8–12.4) was investigated in this study.
