Blast Furnace Slag - Material Description - User ...
and blast furnace slag production. Air-Cooled Blast Furnace Slag. If the liquid slag is poured into beds and slowly cooled under ambient conditions, a crystalline structure is formed, and a hard, lump slag is produced, which can subsequently be crushed and screened. Expanded or Foamed Blast Furnace Slag
Blast Furnace Slag - Material Description - RMRC
Air-Cooled Blast Furnace Slag Crushed ACBFS is angular, roughly cubical, and has textures ranging from rough, vesicular (porous) surfaces to glassy (smooth) surfaces with conchoidal fractures. There can, however, be considerable variability in the physical properties of blast furnace slag, depending on the iron production process.
Blast Furnace Slag | National Slag Association
Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.
Blast Furnace Slag - User Guideline - Granular Base - User ...
Gradation: Blast furnace slag should be crushed and screened to produce a material that satisfies the grading requirements of granular base and subbase specifications, such as AASHTO M147. Compacted Density : The compacted density varies with size and grading of the slag, method of measuring, and bulk specific gravity of the slag.
1. PRODUCT NAME BLAST FURNACE SLAG BASE AND …
cooled blast furnace slag is a crushed product having angular, roughly cubical particles with pitted, vesicular surfaces. Granulated blast furnace slag has a cellular structure resulting from rapid quenching in water, is cementi-tious in nature, and sets to form a solid concrete-like mass. Applicable Standards: Air-cooled blast furnace slag
Ground Granulated Blast Furnace Slag - an overview ...
Ground granulated blast furnace slag (GGBS) was employed as the main component of an alternative binder. Ground agricultural gypsum and construction-grade hydrated lime were used as activators in the proportions of 0.88:0.10:0.02 (GGBS:gypsum:lime) by mass as previously discussed (Oliveira et al., 1999).Sisal (Agave sisalana) field by-product was selected from a …

Slag : Air-cooled blast furnace slag (ABS) What is ABS? ... Sinter typically consists of 10% lime derived from calcined dolomitic limestone and crushed fine ores which consist of 60% Fe ( 90% Fe 2 O 3), silica and alumina depending on the source. Approximately 10-20% of sinter is recycled materials from the iron and steel works.
Tarmac | Slag Aggregates
Blast furnace slag can also be used to make Ground Granulated Blast-furnace Slag (GGBS) which is used as a cement replacement in concrete. Blast Furnace Slag Formed during the manufacture of iron, molten blast furnace slag is cooled and processed in three ways to form slag aggregates for different applications.
Can you tell me what “SLAG” is for driveways. Does it ...
Oct 30, 2014 · Hello again, Slag is equivalent to crushed rock for durability. It *solidifies as soon as it comes out of the blast furnace at the steel mill and cools down below 1,000 degrees F.... by the time it is used in paving materials it has long since solidified to glass/ rock like substance and will stay that way forever.

Slag Cement Benefits and Use in Concrete - Slag Cement News
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield ...
Replacement of Aggregates by Industrial Waste Steel Slag ...
Ground Granulated Blast furnace slag (GGBS) is a byproduct for manufacture of pig iron and obtained through rapid cooling by water or quenching molten slag. If slag is properly processed then it develops hydraulic property and it can effectively be used as a pozzolonic material.
4 Aggregate Specifications and Requirements
40 percent. For air-cooled blast furnace sl ag or granulated blast furnace slag sand, the acid insoluble content is required to not be less than 25 % for this application. Acid insoluble requirements do not apply to crushed gravel, limestone, or dolomite sands. The acid insoluble content is determined by ITM 202.
