blast furnace slag cement

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 (6-35% of GGBS) or blastfurnace cement (36-90% 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. It is used as a mud cake modifier for the cementing of oil and gas wells.. Few reports have studied slag binders with high slag proportions (>90%) and low-cost activators (solid waste is used) that have higher performance than cement for backfilling. Granulated blast furnace slag has product codes commencing with 'GBF'. ash and Ground Granulated Blast Furnace slag cement (GGBFS) for R82 – lean mix concrete subbase [1], and also fly ash and/or GGBFS for R83 – Concrete Pavement Base [2], where reactive aggregates are used. Portland Blast-Furnace Slag Cement UltraTech Premium. Slag is a by-product from steel plants, which is obtained from blast furnaces, during the separation of iron from iron ore. Some of top companies that supply Blast Furnace Slag are AfriSam (South Africa), JFE Steel Corporation (Japan) and Tatametaliks (India). Blast furnace slag cement is contained in 1 match in Merriam-Webster Dictionary. The size of its particles is less than 45 microns and specific surface area is about 400 to 600 m 2 /kg. Blast Furnace Slag (BFS) results in production of GGBS which is a by- product of iron industry and have the potential to replace cement in concrete. Learn definitions, uses, and phrases with blast furnace slag cement. The company says that it will use Suez Cement’s CEM III/A ground granulated blast furnace slag (GGBFS) cement to produce concrete for the 96km monorail network. It has been found that using a slag mix for cementing is beneficial economically and technically as well as better for the environment than Portland cement. Granulated Blast Furnace Slag : Granulated blast furnace slag or gbfs is the residue of combustion in the furnace of the steel refining process. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. The beneficial effect of blast furnace slag on the alkali silicate reaction was reported in [44], and the effect has two parts: First, blast furnace slag cement has a denser pore structure than Portland cement, and this hampers different transport processes needed for alkali silica reaction. Enviroment® is a Ground Granulated Blast Furnace Slag which complies with AS3582.2 as supplementary cementitious material. slag cement, is made from iron blast-furnace slag; it is a nonmetallic hydraulic cement consisting essentially of sili-cates and aluminosilicates of calcium developed in a molten condition simultaneously with iron in a blast furnace. 2.7. Ground Granulated Blast Furnace Slag (GGBFS) has a positive effect on the flexural and compressive strength of concrete. Ground granulated blast furnace slag consists of silicates and aluminates of calcium and other bases. This process leads to a glassy, granular product that is then dried and ground into a fine powder. Ground granulated blast furnace slag (GGBFS) is designated in ASTM C 989 and consists mainly of silicates and aluminosilicates of calcium. Bulk density, particle size, porosity, water holding capacity and surface area makes it suitable for use as an adsorbent. Cockburn Cement markets Ground Granulated Blast Furnace Slag (GGBFS).
