Expanded blast furnace slag is angular and cubical in shape, with negligible flat or elongated particles. Due to the action of the water and resulting steam on the solidification process, the open cellular structure of the particles is even more pronounced than particles of air cooled blast furnace slag. Grading Expanded blast furnace slag is ...
Blast-furnace: A furnace used to reduce raw materials into molten iron. Combustion is forced with pressurized air. Air-cooled blast-furnace slag: The material resulting from the solidification of molten blast-furnace slag under atmospheric conditions. Subsequent cooling may be accelerated by application of water to the solidified surface. (This ...

Blast furnace slag is allowed to slowly cool by ambient air, is processed through a screening and crushing plant and is processed into many sizes for use primarily as a construction aggregate. Common uses are as aggregates in ready-mix concrete, precast concrete, hot mix asphalt aggregate, septic drain fields and pipe backfill.
Iron Blast Furnace Slag (BFS) This is the co-product from the reduction of iron ores to produce molten iron and molten slag. 1. When allowed to cool slowly to a crystalline rod< form It becomes a light gray vesicular rock known as Air-Cooled Blast Furnace Slag. Principle uses include:
Slag--Iron and Steel in 1999 - USGS Mineral Resources Program. Processed slag is either shipped to its buyer for immediate use or ... domestically produced air-cooled blast furnace slag, about 9.0.
Blast furnace slag (BFS) is a non-metallic industrial by-product, which is produced in blast furnaces by the melting of the iron ore, producing molten pig iron [1]. Worldwide, more than 500 million tons of blast furnace slag are produced every year [2]. The blast furnace slag can be granulated slag (GBFS) or air-cooled blast furnace slag (ACBFS).
GBFS can be used as a direct replacement for ordinary cement with varying replacement ratio between 30% and 85%. If the molten slag is directed into pits or ground bays where solidification takes place under the prevailing atmospheric conditions, it will form air-cooled blast furnace slag (ABFS) having crystalline structured rock-like mass.

When the molten slag, on leaving the furnace, is not water quenched, it is directed into ground bays to be air cooled. This material is commonly called blast furnace rock slag, and it is a crystalline rock-like material that has little cementitious value and is essentially inert in concrete.
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 …

This is the Turner-Fairbank Highway Research Center. BLAST FURNACE SLAG User Guideline. Embankment or Fill. INTRODUCTION. Both air-cooled blast furnace slag (ACBFS) and expanded blast furnace slag can be used as a conventional aggregate in embankment or fill.
Granulated Blast furnace slag (GBS) is a light coloured 0/4mm glassy sand produced by the rapid quenching of molten blast furnace slag using large volumes of water. Production and Processing . GBS or Granulate as it is sometimes known is produced by rapidly cooling molten Blast furnace slag with water as the slag is tapped from the furnace.

Foamed slag is distinguishable from air-cooled blast furnace slag by its relatively high porosity and low bulk density. Pelletized Blast Furnace Slag. If the molten slag is cooled and solidified with water and air quenched in a spinning drum, pellets, rather than a solid mass, can be produced.
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 iron ore, limestone and coke at a temperature about 1500 degree ...
Use of Air-Cooled Blast Furnace Slag as Coarse Aggregate in Concrete Pavements Final Report Report No. FHWA-HIF-12-008 . March 2012 . Notice—This report is disseminated under the sponsorship of the U.S. Department of Transportation in the interest of …
Pelletized blast furnace slag, in contrast to air-cooled and expanded blast furnace slag, has a relatively smooth texture and rounded shape. Grinding reduces the particle size to a cement fineness for use as a hydraulic cement, which is typically less than 3500 cm 2 /g. (8)
What is the abbreviation for Air-Cooled Blast Furnace Slag? What does ACBFS stand for? ACBFS abbreviation stands for Air-Cooled Blast Furnace Slag.

Air-cooled blast-furnace slag: The material resulting from the solidification of molten blast-furnace slag under atmospheric conditions. Subsequent cooling may be accelerated by application of water to the solidified surface. (This material can be mined and crushed for use as aggregates in concrete or fill material; it is not cementitious).

In the same way as air-cooled blast furnace slag, converter slag is cooled slowly by natural cooling and water spray in a cooling yard. It is then processed and used for various iron and steel slag (converter) applications. Approximately 110 kg of slag is generated for each ton of converter steel.
This paper is the first in a series presenting engineering data sets that successfully supported the permit approval process in a US midwestern state bordering the Great Lakes to use air-cooled blast furnace (ACBF) slag for phosphate removal in passive stormwater runoff systems.
