1.1 Blast-Furnace Slag—An Overview 1.1.1 History of Blast-Furnace Slag The latent hydraulic reactivity of granulated blast-furnace slag (gbfs) was discov-ered in 1862 by Emil Langen in Germany (Lea 1971; Smolczyk 1978). The first use of slags in cements dates back to 1865, when in Germany a slag-lime cement was commercially produced.

Slag cement or GGBFS is granulated blast-furnace slag that has been finely ground and that is hydraulic cement. When slag cement is mixed with water, however, the initial hydration is much slower than portland cement mixed with water; therefore, portland cement or salts of alkali metals, principally sodium and potassium or lime, are used to ...

The rapid quenching ("granulation") "freezes" slag cement in a glassy state and imparts cementitious properties to the product when ground finely. Blast furnace slag aggregate comes in two forms: Air cooled blast furnace slag, results when molten slag from a blast furnace slag cools slowly by ambient air (as opposed to rapid quenching), and is ...

The goal of the current study is to determine the dissolving effect of slag in water. Five percentage values of slag were taken up for the study: 0%, 2.5%, 5%, 10%, and 20%. The study is based on two methods of mixing. The first method is the traditional mixing process, which involves addition of slag directly with other concrete proportions …

What is Ground Granulated Blast Furnace Slag (GGBFS) GGBFS is a byproduct of the iron and steel industry, specifically from the production of iron in blast furnaces. It is obtained by rapidly quenching molten slag from the blast furnace with water or steam, which results in the formation of glassy granules.
