Air-cooled blast furnace slags ABS are a crystalline by-product produced by the solidification of molten blastfurnace slag. Production and Processing Iron production is via a continuous batch process with the iron and slag produced in the blastfurnace at a temperature around 1500ºC.
BLAST FURNACE SLAG USAGE AND GUIDANCE FOR INDIANA Introduction INDOT permits the use of air cooled blast furnace slag (ACBFS) as a conventional aggregate. The material can be used in granular base, hot mix asphalt, Portland cement concrete, embankments, and fill applications. ACBFS has been used in unbound applica-
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).

Jul 14, 2012· Morphology characteristics of mix aggregates with crushed air-cooled blast furnace slag (SCR) and crushed limestone (LCR) with 5–20 mm and 20–40 mm gradation were represented by numerical parameters including angularity number (AN) and index of aggregate particle shape and texture (IAPST). The effect of mix aggregates containing SCR on compressive strength and splitting …
Oct 04, 2018· This paper is the second in a series on the potential use of air-cooled blast furnace (ACBF) slag for phosphate (PO 4) removal from passive stormwater runoff systems—that is, the ACBF slag aggregates function as reactive base/subbase layers beneath porous pavement systems.Batch tests containing simulated stormwater stock solutions of 1, 5, and 10 mg / L PO 4 were equilibrated with …
The chemical composition of slag from a given source varies within relatively narrow limits since raw materials charged into the furnace are carefully selected and blended. Formed during the manufacture of iron, molten blast furnace slag is cooled and processed in three ways to form slag aggregates for different applications.
After cooling to 93°C (200°F) or lower, the slag is transported to a plant for crushing and screening to a size appropriate for concrete use (Dobrowolski, 1998 ). Air-cooled blast furnace slag has been extensively used as a construction aggregate. View chapter Purchase book. Read full chapter.
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.
The normal blast furnace operation type is characterized by smooth inner wall surface and stable slag skin. However, in actual blast furnace production, due to the influence of changes in the slagging system, charging system, air supply system, thermal system, and external raw materials, the blast furnace operating furnace model will undergo changes such as sticking or slag peeling, which will ...
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.
Blast furnace slag is a versatile, economical byproduct of production of iron. The four distinct methods of processing molten blast furnace slag - air cooled, expanded, pelletized and granulated - produce unique materials, although all varieties of blast furnace slag …
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.
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).
The air cooled blast furnace slag, granulated slag, lime mixes and the air cooled blast furnace slag, granulated slag, basic oxygen steelmaking slag mixes exhibited the characteristics of excellent stabilised base materials (A). (TRRL) Corporate Authors: Newcastle University, Australia. Newcastle, New …
When it is ejected from a blast furnace, the slag is molten at a temperature of approximately 1,500℃. Depending on the cooling method used, it is classified either as air-cooled slag or granulated slag. Air-cooled slag The molten slag flows into a cooling yard, where it is cooled slowly by natural cooling and by spraying with water.
Nov 15, 2016· Air-cooled blast furnace slag (ACBFS) is produced by the solidification of the molten slag that forms at the top of the molten iron in a blast furnace under ambient conditions. It is reported that in 2012, 47.5% of the ACBFS was used as road base and in road surface layers, 21.1% in asphalt concrete, whereas only 13.1% of the ACBFS was used as ...
Air-cooled slag (ABS) Cooled slowly by ambient air, the slag is processed into different sizes for use primarily as a construction aggregate in ready-mixed and precast concrete, asphalt and, as a fill material. Also used as a filter media in water and sewage treatment. The largest air-cooled slag aggregate product, called riprap, is used to ...
