Slag : Ground granulated blast furnace slag (GGBS) GGBS is primarily a latent hydraulic binder used as a type 2 addition to cement which produces Portland blastfurnace cement (635% of GGBS) or blastfurnace cement (3690% GGBS) which is produced primarily by blending at the concrete mixer but can also be used to produce factory blends generally at the cement factory.
The refining process using an aluminum deoxidizer for fabricating stainless steel generated steel slag (STSrefining slag (SRS)) that contains a large amount of Al2O3 and is a compound of mainly 12CaO·7Al2O3 and 3CaO·Al2O3. When SRS was mixed with slag cement, rapid exothermic reaction occurred in the initial phase of hydration.
The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.

Slag : Aircooled blast furnace slag (ABS) What is ABS? ABS is a crystalline byproduct produced by the solidification of molten blastfurnace slag. Production and Processing. Iron production is via a continuous batch process with the iron and slag produced in .
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine granulated blast furnace is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing ...
In order to compare the properties of alkaliactivated carbon steel slag (CSS) and stainless steel slag (SSS), the effects of sodium hydroxide/sodium silicate solution mass ratio (NH/NS), liquid/solid ratio and blast furnace slag (BFS) dosage on the compressive strength, hydration products and hydration degree of CSS and SSS were studied.
Stainless steel slag waste 93 The stainless steel slag waste used in this investigation was obtained from a producer of 94 ferritic stainless steel produced by a steel plant Acerinox in Algeciras, Cádiz, Spain. The 95 steel slag is produced during the direct reduction of iron in an electric arc furnace.
