Slag Cement. 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. The iron is used to produce steel, and the

is normally less than 3% in the slag. Iron content including FeO, Fe0, and Fe 2O 3 is another important factor to evaluate the possibility of slag as cement due to the concerns on the volume stability and appearance. Generally, the production of cement from slag can be simply processed as grinding, treating, and blend-ing. The order of the procedure is varied based on the treatment methods

SLAG - IRON AND STEEL - IBM

The iron content is the major basic difference between BF slag and steel slag. In BF slag, FeO is around 0.70%, whereas in case of steel slag, total iron content varies from 16 to 25%. JSW Steel has set up a unique BOF slag granulation plant, producing slag with lower free lime content and is vigorously pursuing with BIS.

Slag recycling - recovery

With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron. In the case of inferior grade ores below 60 %, the amount of slag is typically 0.35 to 0.50 slag/t of pig iron [1].

Iron and Steel Slag Statistics and Information

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 reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and

Some literature reported that, if iron could be lowered by one or the other method/s, can be use in cement making and more suitable than BF slag because of high basicity.

233R-17: Guide to the Use of Slag Cement in Concrete and

The use of slag cement as a cementitious material dates back to 1774, when a mortar was made using slag cement in combination with slaked lime (Mather 1957). In 1862, a granulation process was proposed to facilitate removal and handling of iron blast-furnace slag leaving the blast furnace. The use of granulation produced glassy material that played
