The resultant product is portland slag cement. Portland blast furnace slag cement contains up to 60% ground granulated slag from steel production processes. Slag cement has low heat of hydration, low alkali aggregate reaction, high resistance to chlorides and sulphate and it can substitute the use of 43 and 53 grades of ordinary Portland Cement.

In the same way as aircooled blast furnace slag, converter slag is cooled slowly by natural cooling and water spray in a cooling yard. It is then processed and used for various iron and steel slag (converter) applications. Approximately 110 kg of slag is generated for each ton of converter steel. Electric arc furnace slag
Processing slag at the mill site. Blast furnace slag (BFS) and steel furnace slag (SFS) have a long history of being utilized as industrial byproducts, going back almost 100 years in the United States. BFS is composed of the nonmetallic components removed from iron ore during processing in a blast furnace.

slag is one of them. Blast furnace slags are byproducts of metallurgical processes. Steel and iron making industries generate different types of slag. Blast furnace slag, which is a byproduct of iron making process, has a high SiO 2 content and hence rapidly cooled blastfurnace slag, has an amorphous structure and pozzolanic properties ...
In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense readymixed concrete. Blast furnace slag can also be used to make Ground Granulated Blastfurnace Slag (GGBS) which is used as a cement replacement in concrete.

Nov 19, 2018· In total, between 1– million tonnes of metallurgical slag were produced at iron and steel plants in Sweden during 2010. This production was distributed among a series of different slag types: blast furnace slag, LD slag, electric arc furnace slag, AOD slag, ladle furnace slag and slag from desulphurisation.
Granulated Blast furnace slag (GBS) is a light coloured 0/4mm glassy sand produced by the rapid quenching of molten blast furnace slag using large volumes of water. Production and Processing . GBS or Granulate as it is sometimes known is produced by rapidly cooling molten Blast furnace slag with water as the slag is tapped from the furnace.
Waste slag as alternative raw material in the cement production . Ferrous slag is produced by adding slagging agents such as limestone or dolomite and/or fluxing materials to blast furnaces and steel furnaces to strip the impurities from iron ore, steel scrap, and other iron or steel input feeds.
