blast furnace slag binder

Blast furnace slag-the ultimate binder Semantic Scholar

The slag that has a chemical role in removing sulfur from molten iron rises to the surface and is tapped off from the blast furnace. Blast furnace slag is a versatile material. If it is air-cooled slowly in pits, it gives a crystalline product resembling an igneous rock and consisting of a mixture of minerals of which melilites are the main series.
