Ferrous Slag – general information - Euroslag
Iron and steelmaking slags (ferrous slags) are co-products of the iron and steel making industry. They are non-metallic rock-like materials which are produced together with the metallic products of these processes. Depending on the iron and steel production process different slag types can be manufactured.
Euroslag - Euroslag
Ferrous slag is the by-product of iron and steel manufacturing. It arises from the conversion of ores to iron, hot iron to steel, from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel. Each year, about 45 million tonnes of ferrous slag (iron and steel slag) is generated in Europe.
slag in concrete Topic
30.07.2020 · The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. Various types of slag are produced: - Blast-furnace slag—The nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast furnace…
Slag Aggregate - an overview | ScienceDirect …
A synthetic aggregate may also be the byproduct of manufacturing and a final burning process—blast furnace slag is an example of a synthetic aggregate. Briefly, blast furnace slag is formed when iron ore or iron pellets, coke, and a flux (such as limestone, CaCO 3, or dolomite, CaCO 3 ·MgCO 3) are melted together in a blast furnace.
Characteristics and applications of iron and steel …
Today, iron and steel slag is used in many fields where its unique characteristics can be put to effective use. As a result of growing environmental awareness, iron and steel slag is highly regarded as a recycled material that can reduce impacts on the environment due to its resource-conservation and energy-saving effects.
Properties of Slag Concretes - P2 InfoHouse
Ground granulated iron blast-furnace slag has been in use in Australia since the mid-sixties. On the east coast, slag as a cement alternative in the form of milled slag and in blended cements did not enjoy continuous availability until its reintroduction in 1982.
Slag Cement - Lehigh Hanson, Inc.
Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag.

What is Slag? | Australian Steel Mill Services
Blast Furnace Slag is a co-product of the iron making process. It is removed from the blast furnace and allowed to cool. ASMS then further process the blast furnace slag into useful products for the construction industry such as concrete aggregates and road base products.
Slag | Cement Australia
Ground-granulated blast-furnace slag (GGBFS) is produced by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water, to produce a granular product that is then dried and ground into a fine powder.
Iron and Steel Slag Statistics and Information - …
Slags are nonmetallic byproducts of many metallurgical operations and consist primarily of calcium, magnesium, and aluminum silicates in various combinations. Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the
