 · Basic Oxygen Furnace slags are byproducts of the conversion of pig iron to steel in a Basic Oxygen Furnace (BOF). The operating principle of pig iron refining is to blow oxygen in order to oxidize carbon and then decrease the carbon content. During this operation, lime is added in the converter in order to fix undesirable elements in slag and protect refractory lining. At the end of the ...

GBFS is slag from the iron production in Basic Oxygen Furnaces. When this slag is actively cooled and ground, GBFS is produced, which can be utilised as a cement or concrete addition. GBFS is said to increase durability of concrete due to an increased setting time, which reduces the possibility of cracks. This increased setting time can be problematic in some appliions of concrete. Precise ...
