Molten blast furnace slag, which is rapidly quenched from the furnace, air-cools slowly to form . Ground Granulated Blast Furnace Slag (GGBFS) has a positive effect on the flexural and compressive strength of concrete. It also needs longer period to gain required strength. UltraTech Premium is a concrete special cement, produced in UltraTech's state-of-the-art manufacturing facilities with carefully selected premium ingredients to deliver to the customer cement that produces both exceptionally strong as well as exceptionally durable concrete. Ground granulated blast furnace slag consists of silicates and aluminates of calcium and other bases. 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. Bulk density, particle size, porosity, water holding capacity and surface area makes it suitable for use as an adsorbent. Slag is a by-product from steel plants, which is obtained from blast furnaces, during the separation of iron from iron ore. PRODUCTION OF BOS SLAG. Portland Blast Furnace Slag Cement is particularly suitable for rivers, ports, roads and tunnels. 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. Production and composition. A. Blast-furnace slag is the nonmetallic product consisting essentially of silicates and aluminosilicates of calcium and other bases that develop in a molten condition simultaneously with iron in a blast furnace. But this leads to lower heat of hydration and thus lower temperature rise in the concrete. This product is marketed to the cement industry by ASMS as a cementitious material. The heart of the process is the blast furnace that refines iron ore into iron. When produced at the … It is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. A Guide to the Use of Iron Blast Furnace Slag ii Cement and Concrete. It is a by-product of the iron-making industry. Ground Granulated Blast Furnace Slag (GGBS) is a cement substitute that improves durability and also the environmental credentials of concrete mixes. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. For every tonne of GGBS used in a concrete mix, the embodied CO 2 levels are reduced by around 900 kg compared to the use of one tonne of traditional Portland Cement. Granulated slag is the glassy, granular material formed when molten slag is rapidly chilled. What is GGBFS? IDENTIFICATION OF THE MATERIAL AND SUPPLIER Product Name GRANULATED BLAST FURNACE SLAG Supplier Contact Cockburn Cement A.B.N. 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. Blast Furnace Slag can be processed into another form by Granulation. 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. Blast Furnace Cement (BFC) is created through the addition of blast furnace slag with Portland cement clinker and gypsum. 1 a INTRODUCT Throughout the world there is an increasing focus on the need to recycle and to more fully utilise by-products of manufacturing processes in an attempt to conserve our finite natural resources.
