GGBS is primarily a binder used as an addition to cement which uses the latent hydraulic properties of GGBS to produce Portland blastfurnace cement (6-35% of GGBS) or blastfurnace cement (36-90% GGBS) produced by blending at the concrete mixer, or as a factory blend at the cement factory. When produced at the concrete plant mixer these …

CSIRO has been working on a dry granulation process, integrated with heat recovery, since 2002. It involves a rotary disc that atomizes molten slag to produce liquid droplets, which are rapidly quenched to become solid granules. The hot granules are fed to a counter-current moving packed bed heat exchanger, where they are further cooled …

BOS Slag. Process. When molten iron (referred to as "hot metal") from the blast furnace is to be converted into steel, the main tasks are the removal of carbon, silicon and phosphorus. The LD (Linz-Donawitz) process is by far the most widely used, and takes its name from the towns where it was developed.

Many restrictions exist, however, on the utilization of steel slag. When steel slag is used internally, in steel plants, the most obvious problem is that of the enrichment of P and S (Drissen et al., 2009).The Bhilai Steel Plant in India was shut down because of its high S and P content (Das et al., 2007).The amounts of free lime and free MgO are …

Aluminosilicates can be obtained from natural roots like pozzolan and metakaolin or industrial by-products like fly ash and ground granulated blast furnace slag (GGBFS). GGBFS, an iron production by-product, can produce better quality mixes than OPC and fly ash-based GPC, but its GPC has a lower initial flow and setting time .

10.2.2 Blast furnace slag. Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.

To limit the amount of impurities in the process, the slag-to-liquid ratio should remain below a certain value, which depends on the slag composition. Also, the design of a continuous test setup (total volume ∼75 L) is described, which enables quick process variations needed to adapt the system to the varying slag quality.
