Blast furnace slag is nonreactive in a high alkali environment, such as concrete and soils. Blast furnace slag concrete can be reliably pumped when the slag is supplied to the ready-mix production in a saturated condition. Use of the cementatious properties of ground granulated blast furnace (GGBF) slag was reported as early as 1774. GGBF slag ...

Blast Furnace Slag – IspatGuru

Apr 10, 2013 · Blast furnace slag is mildly alkaline and exhibits a pH in solution in the range of 8 to 10. Although blast furnace slag contains a small component of elemental sulfur (1 % to 2 %), the leachate tends to be slightly alkaline and does not present a corrosion risk to steels in pilings or to the reinforcement steels embedded in concrete structures made with blast furnace slag cement or .

Blast Furnace Cement - an overview | ScienceDirect Topics

Used as a coarse aggregate in concrete, blast furnace slag reduces concrete workability but increases compressive strength, while the splitting tensile strength and modulus of elasticity are similar to those of conventional concrete [49]. Also, concrete with coarse slag aggregate is more resistant to high temperatures; that is, this concrete has more residual compressive strength than conventional concrete.

Slag - Wikipedia

Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route. To flux the silica produced during steelmaking, limestone and/or dolomite are added, as well as other types of slag conditioners such as calcium aluminate or fluorspar ...

What is Slag Cement

Slag cement, or ground granulated blast furnace slag (GGBFS), has been incorporated into concrete projects in the U.S. for over a century to improve durability and reduce life cycle costs. Among its measurable benefits in concrete are better workability and finishability, higher compressive and flexural strengths, and improved resistance to aggressive chemicals.

The blast furnace is the biggest chemical reactor. Blast furnaces are also called high ovens. A blast furnace is usually built with a steel case and bricks made of magnesium oxide or other refractory material inside the case. The hot furnace cannot melt these bricks. The furnace is cooled with water running inside part of the case and bricks.
