Ground Granulated Blast Furnace Slag (GGBS) is a byproduct of Iron industry and which is obtained from during the manufacture of iron. The molten slag is a secondary product of sintering of the raw materials and this is quenched under high pressure of water jets, which results as granulates . The GGBS is obtained when the granulated slag is ...
Blast furnace slag is made during the melting and reduction of iron ore in a blast furnace. Steel making slag (also: steel slag) is produced during the conversion of hot metal to crude steel in a basic oxygen furnace or during the melting of scrap in an electric arc furnace.
of blast furnace slag aggregate (including in-house use) annually in the first half of the 2000s, but due to the latest fall in the demand for concrete aggregate (264 million t in 2011 2)), the sale fell to below 1 million t (see Fig. 2), and it is now necessary to cultivate new fields
93 IRON AND STEEL SLAG Events, Trends, and Issues: Air-cooled blast furnace slag is in declining domestic supply owing to depletion of old slag piles and the closure of many blast furnaces over the years for economic and/or environmental reasons.
With growing opportunities and pursuits, Prakhyath Minerals has emerged as a leading player in the era of excellent quality Ground Granulated Blast Furnace Slag & OPC Cement. As a prime Supplier of it, we ensure that our clients receive the best slag which suits their purpose.
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Blast Furnace Slag is a by product obtained in the manufacturing of Pig iron in the Blast furnace and is formed by the combination of earthy constituents of iron ore with lime stone flux. Quenching process of molten slag by water is converting it into a fine, granulated slag of whitish color.
For years the construction industry has used ground granulated blast furnace slag (GGBFS) as a replacement for ordinary portland concrete cement (OPC) to lower curing temperatures.
Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. These operate at a temperature of about 1, 500 degrees centigrade and are fed with a carefully controlled mixture of iron-ore, coke and limestone.
Slags, ferrous metal, blast furnace The following components comprise this Basic Blast Furnace Slag product and were used for hazard determination: Metallic Silicates and Aluminosilicates * Various Various 94-100
Blast furnace slag is formed during the production of hot metal by thermo-chemical reduction in a blast furnace. During this continuous process, iron ore or pellets as well as fluxes (lime[stone] and/or dolomite) are heated under reducing conditions in the presence of heated air.
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).
Ground Granulated Blast furnace Slag (GGBS)[1] is a by product from the blast furnaces used to make iron. These operate at a temperature of about 1500 degrees centigrade and are fed with a carefully controlled mixture of iron ore, coke and limestone. The iron ore is reduced to iron and the remaining materials from a slag
ground granulated blast furnace (GGBF) slag was reported as early as 1774. GGBF slag has been used in concrete in Japan and Western Europe since the 1940s. Concrete containing slag is estimated to comprise approximately 20 percent of the hydraulic cement produced in Europe.
It is fully called as Ground-granulated blast-furnace slag (GGBS or GGBFS) and is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Grinding of blast furnace slag is conventionally performed in a tube mill with a dryer, which is a power-intensive option. Energy efficiency of this process can be improved by grinding the blast furnca slag using vertical roller mills (VRM) or by using a VRM as a pre-grinding step for the tube mills.
Supersulfated cement usually contains about 80% ground granulated blast furnace slag, 15% gypsum or anhydrite, and a small amount of Portland clinker to act as an activator.[13]
A transparent glass product resulting from the fusion in a glass furnace of a mixture of glass forming materials consisting essentially of sand, from about 20% to 500% based on the weight of the sand of blast furnace slag containing less than 0.3% sulfur, and from about 16% to based on the weight of the sand of an agent selected from the ...
Blast Furnace Slag (BFS) Brief Description . BFS is formed in a blast furnace with molten iron from iron ore in the reducing presence of heated air, coke and limestone. The resulting molten slag and iron, once removed from the furnace, ...

Global Ground Granulated Blast-Furnace Slag (GGBFS) Market Insights, Forecast to 2025 is a market research report available at US $3900 for a Single User PDF .
Blast furnace slag is the main byproduct in the ironmaking process, which contains large amounts of sensible heat. In addition, it''s the major raw material for cement.
blast furnace slag powder as partial replacement of cement 5 to 30%. Compressive strength of blast furnace slag concrete with different dosage of slag was studied as a partial replacement of cement. From the experimental investigations, it has been observed that, the
The blast furnace (BF) slag waste heat was recovered by an integrated system stage by stage, which combined a physical and chemical method. The water and coal gasification reactions were used to recover the heat in the system.
Both Ground Granulated Blast Furnace slag and Iron slag have very similar appearance. The end result of both these slags is entirely different on the mechanical properties of concrete.
