Blast Furnace Slag Blast furnace (BF) slag is a nonmetallic by product produced during the process of iron making in a blast furnace. It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. The molten slag usually absorbs most of the sulfur from the blast furnace charge.
Granulated blast furnace slag Just like air-cooled blast furnace slag, this slag has a hydraulic property and there is no risk of alkali-aggregate reaction. Because of the powerful latent hydraulic property that results from fine grinding, this slag is used in products such as Portland blast furnace slag cement.
Granulation characteristics of molten blast furnace slag by hybrid centrifugal-air blast technique. ... we discussed the influences of the blast air volume flow rate on the granulation characteristics under different granulator rotating speeds and different molten slag mass flow rates. 2.
Blast furnace slag is a non-metallic byproduct consisting essentially of calcium silicates and other bases. The exact concentrations of elements vary slightly depending on where and how the slag …
Slag is a waste product from the pyrometallurgical processing of various ores. Based on over 150 published studies, this paper provides an overview of mineralogical and geochemical characteristics ...
Granulated blast furnace slag or slag sand is the product of rapid quenching of molten blast furnace slag with an excess amount of water to produce a sand-like product. In Australia, granulated slag is used primarily in the production of ground granulated blast furnace cement.
Granulated blast furnace slag can have up to 99.5% reactive glassy material, which accounts for its self-cementing properties. Stabilising binder: one of the major benefits of using slag products in a stabilised pavement is the slow rate of the cementation process.
To enhance general understanding of the physical and chemical characteristics of this material, slag samples from 58 active mills with blast furnaces, basic oxygen furnaces, and/or electric arc …
A laboratory study was conducted to determine the environmental conditions necessary to reproduce leachates observed emerging from blast furnace slag acting as the foundation of highways in northwest Indiana. The leachates in the field are often highly alkaline with a pungent sulfur odor, a distinct ...
Blast furnace slag products have been used successfully in virtually all phases of bridge construction. Projects such as the bridge pictured here can utilize blast furnace slag as a concrete aggregate. Blast furnace slag has been utilized in concrete masonry for many years.
Granulated blast furnace slag and vitrified pelletized blast furnace slag are also used in the manufacture of blended hydraulic cements (AASHTO M240). (3) When used in blended cements, granulated blast furnace slag or vitrified pelletized slag are milled to a fine particle size in accordance with AASHTO M302 requirements.
A study of flow characteristics of blast furnace slag helps determine its softening and flow (liquid-mobility) temperatures. The slag with a narrow difference between the two temperatures is termed a "Short Slag".
