Slag was processed by 28 companies servicing active iron and steel facilities or reprocessing old slag piles at about 129 processing plants (including some iron and steel plants with more than one slag-processing facility) in 33 States, including facilities that import and grind unground slag to sell as ground granulated blast furnace slag (GGBFS).
Iron and Steel Slag Utilization: A Comprehensive Analysis ... This results in a crystalline, rock-like air-cooled slag. Granulated slag is formed when the molten slag is cooled rapidly by jets of pressurized water, ... as per the requirement. Different percentage of slag …
Granulated slag is formed by quenching molten slag in water to form sand-sized particles of glass. The disordered structure of this glass gives the material moderate hydraulic cementitious properties when very finely ground into granulated blast furnace slag, but if it can access free lime, the granulated blast furnace slag develops strong hydraulic cementitious properties.
Requirement Of Free Iron Granulated Slag. As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
The influence of using Ground Granulated Blast Furnace Slag (GGBFS) on various properties of Pavement Quality Concrete (PQC) and performance of concrete pavement has been brought out. The amount of GGBFS in PQC mixes was varied from 10 to 60 percent.
Granulated Blast Furnace Slag is a main by-product generated during iron and steel production in the steel industry. Blast Furnace Slag are generated at two different stages of steel production i.e., Iron making and Steel making, known as Blast Furnace slag and Steel Slag respectively.
granulated slag as a sand substitute. The ingredients of BF slag such as CaO, SiO 2 and MgO are used for fertiliser and soil improvement as well. The production of granulated slag was replaced by air-cooled slag and increased to 80% of total BF slag (Figure 2), in order to meet the demand for BF slag with higher performance.

iron in blastfurnace or electric pig iron furnace. Granulated slag is obtain- ed by further processing the molten slag by rapidly chilling or quenching it with water or steam and air. 3. COMPOSITION 3.1 The physical state of aggregation of granulated slag shall be in the form of granules.
3.1 The physical state of aggregation of granulated slag shall be in the form of granules. The proportion of lumps exceeding 50 mm size shall not constitute more than 5 percent of the mass of slag. 3.2 When tested in accordance with the methods given in IS : 4032-1985*, the composition of granulated slag shall comply with the following chemi- cal requirements:
This slag powder has optimum setting time with high compressive strength. Low heat of hydration, low alkali content and excellent setting time is qualities of offered furnace slag powder. Moreover, our clients can purchase this Granulated Iron Blast Furnace Slag Powder in plentiful packaging options in accord with customers needs.
Blast Furance Slag is a nonmetallic co-product which is produced in the process of iron manufacturing, Granulated Blast Furnace Slag is a glassy granular material formed when molten blast furnace slag is rapidly cooled by direct water.
granulated slag. KIC Metaliks, West Bengal reported production of 41,365 tonnes of granulated slag. Uttam Galva Mettalics reported production of 331,077 tonnes of Granulated Slag. The information regarding plant-wise capacity of iron and steel slag in the country is given in Table- 1.
Normally, blast furnace slag is either quenched by water (granulated slag) or slowly cooled in air. In 2013, nearly 82% of the blast furnace slag was quenched by water [ 2]. Converter slag and electric arc furnace slag are generally slowly cooled at a slag yard in air. Almost 72% of blast furnace slag is used as cement, and other main uses are road
In particular, in a steel slag the free calcium oxide content is reduced, on granulating to a porous granulated steel slag, from about 5 to 6% to 0.1%. Moreover, the porous granulated steel slag obtained can be made more valuable by the magnetic removal of the iron from the granulated slag. This technique is know. Read More →
17-02-2014· The BF Slag. All of the iron making slag generated today can be utilized. Based on application, the slag is treated in one of the following two ways after exiting the BF. Quenching: The slag is poured in a stream of water which cools it immediately. The water is then filtered out to obtain slag granules.
29-10-2019· Granulated blast furnace slag (GBFS) was taken from Kirloskar Ferrous Industries Limited, Koppal, Karnataka, India, located at 15.335547° N, 76.278816° E. Marine clay was replaced by granulated blast furnace slag in various percentages (10%, 20%, 30%, 40% and 50%) and cement was added in various percentages (2%, 4%, 6%, 8% and 10%) of the dry weight of soil.
