As with fly ash, processing blast furnace slag into slag cement or slag aggregate eases the burden on our environment in a number of ways It reduces the air emissions at the blast furnace as well as the material in landfills Most significantly, slag decreases Portland cement usage by as much as 50 percent, thereby diminishing CO2 emissions
Granulated Blast Furnace Slag is obtained by rapidly chilling (quenching) the molten ash from the furnace with the help of water During this process, the slag gets fragmented and transformed into amorphous granules (glass), meeting the requirement of IS 12089:1987 (manufacturing specification for granulated slag used in Portland Slag Cement)
Blending of pozzolans with Portland cement is of limited interference in the conventional production process and offers the opportunity to convert waste (eg fly ash) into durable construction materials A reduction of 40 percent of Portland cement in the concrete mix is usually feasible when replaced with a combination of pozzolanic materials
Silica fume, also known as microsilica, (CAS number 69012-64-2, EINECS number 273-761-1) is an amorphous (non-crystalline) polymorph of silicon dioxide, silicaIt is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm
Slag cement is a recovered material from the iron production process and because of this, reduces the environmental impact of concrete mixtur Additionally, slag cement is very effective in reducing permeability and increasing durability in concrete Click the links below to learn more on slag cement and how it creates a more sustainable .
In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (012 in) to 25 millimetres (098 in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage

Safety Data Sheet Slag Cement Section 1 Identification GHS product identifier: , Any concentration shown as a range is to protect confidentiality or is due to process variation Slag is a nonmetallic byproduct from the production or iron Trace amounts of chemicals may be ,
The most important method of regulation used with the low-percentage Al2O3 slag cements in the USA is the Whiting process This process includes the use of caustic soda, caustic potash, sodium chloride, &c, added either as aqueous solution or in a dry state at some stage of the process of cement ,
Slag cement replaces as much as 50 percent in normal concrete (and up to 80 percent in special applications such as mass concrete) Fly ash is usually limited to 20 or 30 percent Slag cement is the co-product of a controlled process, iron production, which results in a very uniform composition from source to source
Among these three kinds of slag, GGBFS is the most valuable one in cement industry Due to its cementitious properties mixing with lime, alkalis or Portland cement, GGBFS is often used to make blast-furnace slag cement The history of the production of slag cement in Germany, France, Luxembourg and Belgium has been more than one century
Slag cement, or ground granulated blast-furnace slag (GGBFS) is a recovered byproduct of the iron manufacturing process and can be used to replace a portion of portland cement in concrete mix design To learn more about how slag cement is created, click here
Blast furnace slag, an essential part of the blast furnace process, is increasingly sold as a valuable by-product to cement producers When selecting a slag composition, competing requirements must be considered to meet blast furnace and cement producer needs To better understand the optimum slag .
