Ground granulated blast furnace slag is produced in a blast furnace where iron ore is converted into iron. This slag forms when the silica and alumina compounds of the iron ore combine with the calcium of the fluxing stone (limestone and dolomite). The newly formed slag floats on the liquid iron and is drawn off from a notch at the top of the ...
May 09, 2018· Ground Granulated Blast Furnace Slag (GGBS) The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs proper method for disposal. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components such as cement, fine .
Slag. Slag is produced during the ironmanufacturing process. During the manufacturing process the materials are heated in a blast furnace to a molten state. The slag rises to the top and is separated from the iron for further processing. When slag is separated from iron and rapidly cooled with water (granulated), the morphology of the 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. Blast furnace slag is used predominately as base and concrete aggregate ...
This blast furnace slag is used to make a cementitious material by grinding it into a fine powder, which is called Ground Granulated Blast Furnace Slag or GGBS. The same blast furnace slag is used to make a glassy granular product (GBFS) which can be used as fine aggregate.
Attempt has been made to collect information about the locally available constituents of geopolymer ... Granulated BlastFurnace Slag (GGBS) based Geopolymer ... Geopolymer concrete is produced by ...
Granulated Blast furnace slag (GBS) is a light coloured 0/4mm glassy sand produced by the rapid quenching of molten blast furnace slag using large volumes of water. Production and Processing . GBS or Granulate as it is sometimes known is produced by rapidly cooling molten Blast furnace slag with water as the slag is tapped from the furnace.
Non ferrous slags make up only 12% of the total annual production Described below are the main types and uses of slag commercially available in Ferrous Slag products . Iron Blast Furnace Slag (BFS) This is the coproduct from the reduction of iron ores to produce molten iron and molten slag. 1.
blast furnace" [1]. It results in the production of gas com pounds (blast furnaces gas), of liquid (slag castiron), and of solid (gas dust). The granulated blast furnace slag may be used to make blast furnace slag cement either by being interground with the Portland cement clinker or by grinding the blast furnace slag separately and then blend
Granulated Blast Furnace Slag Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than mm (No. 4 sieve) in diameter to dense, sandsize grains passing a mm (No. 4) sieve.
Slag is a grainy, grey and metallic byproduct of steel production that can be used to produce slag cement and composite cement. One of the most sustainable construction materials available, slag decreases greenhouse gas emissions and the use of materials. ... Shun Shing Group trades both granulated blast furnace slag and ground ...
Granulated Blast Furnace Slag. Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than mm (No. 4 sieve) in diameter to dense, sandsize grains passing a mm (No. 4) sieve.
(2) Granulated slag is the glassy, granular product formed when the molten blast furnace slag is rapidly chilled by immersion in water. Basic Use: Aggregates are used for all types of base and subbase construction. In addition to applications requiring graded aggregates, pit run blast furnace slag is extensively used for subbase
The physical properties of Ground Granulated blast furnace slag (GGBFS) provides advantages to the concrete in fresh state as well as in its hardened state. It is always recommended for a concrete mix design, that would provide us with a denser mass of concrete, a solid that is free from voids ...
The promotion of blast furnaces slag in construction industry aims at protecting the environment, fighting against the nuisance such as waste dumps and promoting local products. The use of granulated slag as a part replacement of Portland cement or in the production of clinker free binder constitutes a valuable outlet for this product. The aim of this study is the characterization of local ...
Slag cement is often referred to as "ground granulated blastfurnace slag" (GGBFS). As requested in 2001 by slag cement manufacturers and the Slag Cement Association, the American Concrete Institute officially reviewed and changed the terminology from GGBFS to slag cement (ACI Committee 233, 2004).
Use of Blast Furnace Slag Aggregate in Concrete Hiraskar and Chetan Patil AbstractThe Iron industries produce a huge quantity of blast furnace slag as by–product, which is a non–biodegradable waste material from that only a small percentage of it is used by .
Francis Flower recycles blast furnace slag from the steel industry for production of ground granulated blast furnace slag for use in cement production, among other offerings for industrial and agricultural use. It employs 130 people across four sites in the UK: Scunthorpe, Wicken, Gurney Slade and Runcorn.

As is well known, cement, which accounts for about 20% of the volume of concrete, is its most expensive constituent. The huge quantities of granulated blast furnace slag produced by this plant have mainly been used by the local cement factories to develop a CEM II type cement (Composed Portland Cement).
Blast furnace slag (BFS, see Wikipedia ground granulated blastfurnace slag) is a nonmetallic byproduct of the manufacture of pig iron in a blast furnace. BFS consists primarily of silicates, aluminosilicates, and calciumaluminasilicates.
These guidelines on ground granulated blastfurnace slag substitution rates are intended to provide a starting point for designers with little or no experience in the use of cement and concrete containing ground granulated blastfurnace slag. If local data shows good performance at greater percentages, this information can be used in lieu of ...
