Ground granulated blast-furnace slag - Wikipedia
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. Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing compound which improves the strength, durability and appearance of the concrete.
Blast Furnace Slag - Material Description - User ...
Granulated Blast Furnace Slag. Granulated blast furnace slag is a glassy granular material that varies, depending on the stone composition and method of production, from a coarse, popcornlike friable structure greater than 4.75 mm (No. 4 sieve) in diameter to dense, sand-size grains passing a 4.75 mm (No. 4) sieve. Grinding reduces the particle size to cement fineness, allowing its use as a ...
Ground Granulated Blast Furnace Slag (GGBS) | …
Ground Granulated Blast Furnace Slag concrete. GGBS hardens very slowly so it is generally used along with ordinary Portland cement in concrete. A typical combination is 50% GGBS and 50% ordinary Portland cement. But percentages of 20 to 80 are commonly used. Greater the percentage of GGBS, greater will be the effect of GGBS in concrete.
Characteristics and applications of iron and steel …
This slag hardens when it reacts with water, with a hydraulic property that provides increasing strength over time. Because of its large load-bearing capacity, it is used in road base course material in the same way as gravel. There is no risk of alkali-aggregate reaction, and this slag contains no clay or organic impurities. As a result, it is also used as a concrete aggregate in the same way as natural …

Properties. stone properties of different types of ferrous slag vary depending on the specific production process. A common characteristic of these slags is that they result from lime and silica based melts, therefore calcium oxide (CaO) and silica (SiO 2) are their primary components.Other components include alumina (Al 2 O 3) and magnesium oxide (MgO).

Copper Slag - an overview | ScienceDirect Topics
Granulated copper slag is more vesicular and porous and therefore has lower specific gravity and higher absorption than air-cooled copper slag. In general, the specific gravity of copper slag will vary with its iron content. The unit weight of copper slag is higher than that of conventional aggregate. As a general rule, the specific gravity will vary with iron content, from a low of 2.8 to as ...

Slag - Wikipedia
Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...

Liquid slag produced in a blast furnace (BF)is at a temperature of around 1500?C and has a sensible heat of around 400Mcal/ton. BF slag is rich in CaO, SiO2, Al2O3, and MgO which are similar to the components of Portland cement. When this liquid BF slag is cooled fast enough then the solidified slag has a large percentage of glassy phase with high cementations activity and hence it can be used ...
