Mar 01, 2019· 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.
furnace slag aggregate crushing plant - woodenlacecoza. crushing lightweight slag aggregate - ekopradeu Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either, is processed through a screening and crushing plant and is processed into many, Due to its reduced weight, it is perfectly suited for aggregate in lightweight.
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

Ground granulated blast-furnace slag (GGBFS), sometimes simply referred to as "slag", is a glassy granular material formed when molten blast-furnace slag is rapidly chilled, as by immersion in water. It is a non-metallic product, consisting of silicates and aluminosilicates of
Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.

In addition to environmental benefits, the use of recycled aggregates in pavement concrete lowers the overall, Blast Furnace Slag and Dolomite as Coarse Aggregates Blast furnace slag HOME: Euroslag Blast furnace slag is formed during the production of hot, Get Price
HOME > About Iron and Steel Slag > Types of iron and steel slag. ... When it is ejected from a blast furnace, the slag is molten at a temperature of approximately 1,500℃. Depending on the cooling method used, it is classified either as air-cooled slag or granulated slag.
Corrosivity: Blast furnace slag is mildly alkaline, with a pH in nonstagnant water mixtures in the range of 8 to 10. Despite the fact that blast furnace slag contains a small component of elemental sulfur (1 to 2 percent), the leachate is slightly alkaline and does not present a …

Slower cooling leads to crystallization of a number of minerals; the ... The chemical composition of blast furnace slag is a significant factor in the potential.
Air-Cooled Blast Furnace Slag. If the liquid slag is poured into beds and slowly cooled under ambient conditions, a crystalline structure is formed, and a hard, lump slag is produced, which can subsequently be crushed and screened. Expanded or Foamed Blast Furnace Slag
Aggregates - general information - Euroslag. The aggregate standards contain additional requirements for blast furnace slag and steel slag with respect to volume stability In general the properties of iron and steel slag aggregate are comparable with the properties of natural aggregateFor some specific uses slag is even superior to natural aggregate
Pelletized blast furnace slag, in contrast to air-cooled and expanded blast furnace slag, has a relatively smooth texture and rounded shape. Grinding reduces the particle size to a cement fineness for use as a hydraulic cement, which is typically less than 3500 cm 2 /g. (8)
Smelting - Wikipedia, The Free Encyclopedia Flux and slag can provide a secondary service after the reduction step is complete: In this, a blast furnace was used to make pig iron, which then had to undergo a further process to make forgeable bar iron.
The formation of all kinds of minerals in slag is influenced by the cooling rate and slag chemical composition. For blast furnace slag, rapid cooling results in a noncrystalline structure with a high amount of glass, which is responsible for its hydraulic activity.
Euroslag is the European association of all main organisations and companies concerned with all aspects of manufacturing and utilisation of ferrous slag products. Thessaloniki's main university, Aristotle University (AUTH), is the largest in Greece and in the Balkans.
PROPERTIES: Euroslag. In contrast to blast furnace slag, basic oxygen furnace slag (BOS) and electric arc furnace (EAF) slag (steel slags) are generated in an oxidizing process and therefore have iron contents that are In the end, the chemical, mineralogical and physical properties of iron and steel slags are similar to those of natural rocks. Thus
Blast furnace slag - HOME: Euroslag. Blast furnace slag is formed during the production of hot metal by thermo-chemical reduction in a blast furnace. During this continuous process, iron ore or pellets as well as fluxes (lime[stone] and/or dolomite) are heated under reducing conditions in …
Blast furnace slag. Blast furnace slag is formed during the production of hot metal by thermo-chemical reduction in a blast furnace.During this continuous process, iron ore or pellets as well as fluxes (lime[stone] and/or dolomite) are heated under reducing conditions in the presence of heated air.
The steel industry produces not only metal, but also a by-products which has been successfully used in many construction or agriculture applications. Nowadays, about 87 wt% of ferrous slag produced in Europe is used for building purposes. Using slag instead of natural materials is a sustainable alternative with high durability in several applications.

Blast furnace slag granulation at cast house. Blast Furnaces normally generate 250 to 350 Kg of liquid slag for every ton of hot metal produced. This molten slag is at around 1400 – 1550 deg C temperature. Till seventies blast furnace (BF) slag was considered a waste product and was being dumped at a convenient place away from the blast furnace.
