Granulated blast furnace slag is a by-product from the iron industry available in large quantities. Since it has high percentage of CaO (i.e. 30–45%), it has latent hydraulic properties.
Ground granulated blast-furnace slag (GGBFS), sometimes simply referred to as "slag", is a glassy granular material formed when molten blast-furnace slag is rapidly chilled, as …
The mix proportion of concrete in this paper is shown in Table 2.A total of 12 groups of concrete mixtures were designed. For the first nine groups, a fixed w/b ratio of 0.38 was used, and they were used to examine the influences of fly ash and GGBFS on the development of the mechanical properties of the concrete.
Granulated blast-furnace slag (GBFS) and unclassified low calcium fly ash were used as sole binders for alkali-activated concretes. Liquid sodium silicate with silica modulus of 1.15 was used as ...
Ground granulated blast furnace slag (GGBFS) is known to possess latent hydraulic activity, i.e., it shows cementitious properties when in contact with water over a long period of time.Results are presented in this article to show that, in sharp contrast to published literature on the hydration of neat GGBFS, the complete hydration of slag is possible in a short time (days), even without a ...
It is converted to granulated blast furnace slag (GBFS) or ground granulated blast furnace slag (GGBFS) by quickly cooling molten slag with industrial water or air. Headquarters. ...

Ground Granulated Blast Furnace Slag (GGBFS), otherwise known as slag, is a by-product of the steel and iron industry which is milled to a fine consistency.
GGBFS is formed when granulated blast furnace slag (GBFS) is further processed or ground using conventional cement clinker grinding technology. On a casual examination, GGBFS can be off-white in appearance and could pass …
In this study, soft clay was stabilized with ground granulated blast furnace slag (GGBFS) and fly ash (FA)-based geopolymer, which is a mixture of solid aluminosilicate precursor (Al-Si raw ...
Ground granulated blast-furnace slag (GGBFS) is a byproduct of making iron and steel, i.e., a fine powder grounded from the glassy, granular material that forms when molten iron blast furnace …
Granulation occurs when the molten slag (2,650° F to 2,800° F) is quenched with large quantities of water. This results in granulated blast furnace slag (GBFS). The granules are similar in size and appearance to beach sand. GBFS is a …
In this paper, the time development of mechanical properties of concrete mixes with various fly ash and GGBFS was experimentally investigated. Four different cement replacement levels …
In the 1990's, Maxi-Blast became a leading distributor of top quality, heavy-duty pressure blast cabinets. We now offer a full line of suction and pressure blast cabinets that are designed specifically for individual applications such as screw cleaning or ambient deflashing.
Granulated slag is the glassy, granular material formed when molten slag is rapidly chilled. Slag cement or GGBFS is granulated blast-furnace slag that has been finely ground and that is …
The ground granulated blast furnace slag (GGBFS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of …
According to Attah et al. 7, in recent years, there has been a growing interest in identifying sustainable alternatives to traditional stabilizers for various engineering applications.Snail shell ash and ground-granulated blast-furnace slag (GGBS) have emerged as potential candidates due to their abundance and the potential they hold for reducing the …
The granulated blast furnace slag has hydraulicity, and the internal pore structure of the concrete is optimized to a certain extent under the condition of long-age curing. The strength growth rate of long-age granulated blast …

A. Blast-furnace slag is the nonmetallic product consisting essentially of silicates and aluminosilicates of calcium and other bases that develop in a molten condition simultaneously with iron in a blast furnace. Granulated slag is the glassy, granular material formed when molten slag is rapidly chilled.
The iron is drawn off to be further refined into steel, and the slag is tapped off to be granulated. Granulation occurs when the molten slag (2,650° F to 2,800° F) is quenched with large quantities of water. This results in granulated blast …
