This article introduces a commercialised energy-saving cement made by co-grinding OPC clinker with steelmaking slag (steel-slag) and blastfurnace slag that represents a different approach to cutting greenhouse-gas (GHG) emission footprints and conserving natural resources.

Slag cement is often referred to as "ground granulated blast-furnace slag" (GGBFS). As requested in 2001 by slag cement manufacturers and the Slag Cement Association, the American Concrete Institute officially reviewed and changed the terminology from GGBFS to slag cement …
Slag is a product of the steel making process. Once scorned as a useless byproduct, it is now accepted and, often, preferred and specified as it is known to be a valuable material with many and varied uses.
Slagment is the registered trade name of our Ground Granulated Blast Furnace Slag (GGBFS). It is a latent hydraulic binder that is used in concrete and other construction applications as a partial cement replacement material.
Cement from steel slag to cut CO2 7th December 2016 5th December 2016 Eindhoven University of Technology professor of building materials, Jos Brouwers, will be working with industrial partners to investigate whether he can make cement out of steel slag.
The slag is less dense than the cement and has a relatively high fineness, which is double that of cement. The chemical composition of the slag shows a similar content of silica and lime. The lime content of the slag is relatively high, giving it latent hydraulic activity.
Being recycled, slag is a 'Green' material. When using slag as an additive in the kiln, cement manufacturers are producing a product which has the same properties as traditional cement, but with the advantage of a lower Co2 emissions, which lowers carbon footprint of buildings which are built using slag cement.

· The American Concrete Institute. Founded in 1904 and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource worldwide for the development, dissemination, and adoption of its consensus-based standards, technical resources, educational programs, and proven expertise for individuals and organizations involved in concrete …
Hello, I'm wondering how much fly ash or slag is used to replace cement in concrete? If a yard of concrete is roughly 4,000 lbs, my understanding is fly ash might replace 20% of the cement (3,200 lbs cement, 800 lbs fly ash) while slag might replace closer to 50% (2,000 lbs slag, 2,000 lbs cement).
Slag Cement for Use in Concrete and Mortars1 This standard is issued under the ﬁxed designation C989/C989M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
The Slag cement is more resistant to the attack of weathering agencies. Low Cost to compare OPC. It gives a smooth finish because the cement particles are more finesse. Disadvantages: The only disadvantage is the PSC cement could not be used in thin RCC structure since its early strength is less.
Copper slag admixed mortar and concrete showed a lesser amount of leaching than solution due to the complex formation with cement mortar. Hence, copper slag can be used (2.5%) in raw mix for OPC and (35%) in manufacture of PSC.
Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as "the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a
Slag cement decreases permeability of the concrete, thus increasing its long-term durability. Slag cement lowers the heat of hydration of a concrete mixture, which reduces the risk of early age thermal cracking, a major benefit for large or mass concrete placements.

Slag content concrete usually contains 30% slag or higher (by cementitous weight), and Graniterock has specially created LEED compliant mixes with substantial quantities of slag to meet the demands of today's green building initiatives. Ground Granulated Blast Furnace Slag is a …
Slag cement is produced by finely grinding granulated blast furnace slag, a glassy by-product of iron production, and blending it with Portland cement to create a product that has a number of advantages over mixes containing Portland cement.
