Iron blast furnace slag is the major nonmetallic product consisting of silicates and aluminosilicates of calcium. They are formed either in glassy texture used as a cementitious materials or in crystalline forms used as aggregates. Other slags such as copper slag have poz zolanic properties and react with lime.

How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved ...

What is Slag? There are two distinct types of slag produced at the Blupe Steel Port Kembla Site; Blast Furnace Slag and Steel Furnace (or BOS) Slag. BLAST FURNACE SLAG. Iron is extracted from iron ore in a blast furnace by a process known as reduction. The raw materials iron ore, coke and fluxes are fed into the top of the furnace.

Traditionally, the reactivity of blast furnace slag is enhanced by prolonged grinding in a ball mill. Reference may be made to ACI Committee 233, Ground Granulated blastfurnace slag as a cementitious constituent in concrete, ACI Mater J 1995;92(3): 3212, wherein the Portland slag cement produced by existing processes using blast furnace slag have lower early strength and longer setting time ...

Abstract. Ground granulated blast furnace slag (GGBS) is a byproduct from the blastfurnaces used to make iron. Blastfurnaces are fed with controlled mixture of ironore, coke and limestone, and operated at a temperature of about 1,500°C. When ironore, coke and limestone melt in the blast furnace, two products are produced—molten iron ...

Unbound steel slag in contact with groundwater initially increases the pHvalue of groundwater to about 1112 but this 'first flush finite' effect diminishes once lime and magnesia have been washed from the surface. Similarly, blast furnace slag increases the pHvalue and may also deoxygenate stagnant groundwater.

Slag cement, originally known as granulated blastfurnace 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. The iron is used to produce steel, and the molten slag is ...
