Blast Furnace Slag - Material Description - User ...

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 - an overview | ScienceDirect Topics

Expanded blast furnace slag is a small part of the supply of structural lightweight aggregates. Annual production since 1985 has been about 1 million short tons (9×10 5 t); in 1997 that was about 12% of the total lightweight aggregate construction-related usage.

lightweight recycled blast furnace slag - dietisthoofddorp.nl

Blast Furnace Slag | National Slag Association

Air-cooled Blast Furnace Slag rip rap The largest slag aggregate, riprap is a permanent cover of rock used to stabilize shorelines and streambanks, and prevent erosion along slopes and embankments. It is also used in gabion baskets, Mineral Wool manufacture (insulation), and lightweight fill.

UG-Mat Blast Furnace Slag | Recycled Materials Resource Center

Blast Furnace Slag - Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.

Tarmac | Slag Aggregates

In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense ready-mixed concrete. Blast furnace slag can also be used to make Ground Granulated Blast-furnace Slag (GGBS) which is used as a cement replacement in concrete.

Using Slag Cement in Sustainable Construction

Using Slag Cement in Sustainable Construction www.slagcement.org 1 What is Slag Cement? Slag cement, or ground granulated blast-furnace slag (GGBFS), has been used in concrete projects in the U.S. for over a century. Earlier usage of slag cement in Europe and elsewhere demonstrates that long-term performance is enhanced in many ways.

Sustainability for Blast Furnace Slag: Use of Some ...

Jul 03, 2015 · Blast furnace slag is a by-product from blast furnaces which is used to produce iron. Blast furnace slag has been used extensively as a successful replacement material for Portland cement in concrete materials to improve durability, produce high strength and high performance concrete, and brings environmental and economic benefits together, such as resource conservation …

Characteristics and applications of iron and steel slag ...

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.

Road Construction Material – Stein Inc

Durable, strong, and lightweight, blast furnace slag offers high resistance to sulfate attack and alkali-silica reaction. Superior thermal properties, sound absorption and reduced weight loads make blast furnace slag a logical and versatile building material. Many architectural applications require strength, durability with lighter materials.

Slag Cement - Products | Lehigh Hanson, Inc.

Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag.

Tarmac | Blast Furnace Slag

The rapid cooling of molten slag by large quantities of water produces sand-like granule aggregate. Primarily ground into a cement replacement known as ground granulated blast furnace slag (GGBS) this is used in ready-mixed and precast concrete and masonry, floor levelling compounds and high temperature resistant building products.
