The Ground Granulated Blast Furnace Slag (GGBS) is obtained by grinding blast furnace slag in water or steam. This process leads to a glassy, granular product that is then dried and ground into a fine powder. GGBS offers a more sustainable concrete having higher compressive strength, reduced permeability and resistance to chloride and sulphate attacks.
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 increases the strength, durability and appearance of the concrete.
Blast Furnace Slag - an overview | ScienceDirect …
Granulated blast furnace slag (GBFS) is obtained by rapidly quenching the molten slag by using high-pressure water jets. It is glassy granular particles having generally smaller than 5 mm particle size like sand. The GBFS is often used after further processed by drying and then grinding to a very fine powder. GBFS can be used as a direct replacement for ordinary cement with varying replacement ...
Blast Furnace Slag | National Slag Association
Granulated slag is rapidly cooled by large quantities of water to produce a sand-like granule that is primarily ground into a cement commonly known as GGBS (Ground Granulated Blast FurnaceSlag), or Type S slag cement. It is also mixed with Portland cement clinker to make a blended Type 1S cement. Air-cooled Slag. Blast furnace slag is allowed to slowly cool by ambient air, is processed through ...

Ground Granulated Blast Furnace Slag - an …
Slag. Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the ...
Processing of Granulated Blast Furnace Slag and …
The most common process for granulating blast furnace slag involves the use of high water volume, high pressure water jets in direct contact with the molten blast furnace slag at a ratio of approximately 10 to 1 by mass. The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a #4 sieve. The efficiency, which the molten blast furnace slag is ...
Blast Furnace Slag - Material Description - User ...
Granulated Blast Furnace Slag. If the molten slag is cooled and solidified by rapid water quenching to a glassy state, little or no crystallization occurs. This process results in the formation of sand size (or frit-like) fragments, usually with some friable clinkerlike material. The physical structure and gradation of granulated slag depend on the stone composition of the slag, its ...

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 aggregate and coarse ...

Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a saleable product (granulated slag sand used as CO 2-friendly substitute of clinker in cement production) rather than a difficult and costly waste material.Paul Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.
Tarmac | Blast Furnace Slag
The rapid cooling of molten slag by large quantities of water produces sand-like granule aggregate. Primarily ground into a cement replacement known as ground granulated blast furnace slag (GGBS) this is used in ready-mixed and precast concrete and masonry, floor levelling compounds and high temperature resistant building products.
Ground Granulated Blast Furnace Slag
Since the granulated blast furnace slag is ground, it is not round. An admixture is needed to increase workability rather than increasing the water content. GGBFS only provides increased sulfate resistance or resistance to ASR if > 35% by mass is added. The time of set is slightly delayed by approximately 20 minutes, and early compressive strengths are decreased. GGBFS also causes increased ...

Dry Granulation of Blast Furnace Slag - Steel360 …
However, water granulation of liquid BF slag consumes large volumes of water (1000-1500 litres of evaporative loss/ton of liquid slag processed) and can generate acid mist causing air pollution. Also,there is need of a proper water management on one hand and necessity of drying of the granulated slag on the other hand. So, not only the sensible heat of the liquid slag is lost, but it is also ...

This slag is later granulated by cooling it. For this, it is allowed to pass through a high-pressure water get. This result in quenching of the particles which results in granules of size lesser than 5mm in diameter. The main constituents of blast furnace slag are CaO, SiO2, Al2O3 and MgO. These are the minerals that are found in most of the cementitious substances. The particles are further ...
