  • Ground Granulated Blast Furnace Slag an overview

    Ground granulated blast furnace slag (GGBS) was employed as the main component of an alternative binder. Ground agricultural gypsum and construction-grade hydrated lime were used as activators in the proportions of 0.88:0.10:0.02 (GGBS:gypsum:lime) by mass as previously discussed (Oliveira et al., 1999).Sisal (Agave sisalana) field by-product was selected from a variety of Brazilian fibrous

  • Blast Furnace Slag an overview | ScienceDirect Topics

    Molten blast furnace (BF) slag and steel slag are produced simultaneously with iron and steel manufacturing. BF slag results from smelting iron ore, coke, and fluxes during the operations of extracting iron from the iron ore. Steel slag is formed during refining operations converting crude iron into steel by combining fluxes with the nonferrous oxides and other unwanted elements in the raw

  • Dry Granulation of Blast Furnace Slag Steel360 News

    Dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag. Atomization is done using a rotary cup air blast atomizer (Fig 1). The particles cool as they travel through the air and are then cooled further in a fluidized bed. Both of these cooling processes provide the rapid cooling necessary for the formation of

  • Basics of slag production Article on the slag industry

    2011-10-27· Air-cooled Blast Furnace SlagThe simplest treatment of the liquid slag is to lead it into a slag pit where layers build up until the pit is full. When it has fully solidified and then cooled somewhat, the slag (commonly known as air-cooled blast furnace slag or ACBFS) is excavated and transported away for further treatment (such as magnetic removal of any iron, or crushing and screening).

  • Processing of Granulated Blast Furnace Slag and its

    After the granulated blast furnace slag is formed, it must be dewatered, dried and ground, using processes similar to those used with Portland cement clinker to make Portland cement. Typically, granulated slag is ground to an air-permeability (blaine) fineness exceeding that of Portland cement to obtain increased hydraulic activity at early ages. As with Portland cement and pozzolans, the rate

  • Investigating the Local Granulated Blast Furnace Slag

    Mechanically activated granulated blast furnace slag was used in the range of 20% 75% to replace clinker in Portland slag cement. The slag and clinker were acti- vated separately using a mill and mixed to prepare ce-ment formulations [4]. Use of activated slag resulted in a remarkable increase in strength vis-à-vis slag cement. Both 2-day, 28-day and 90-day strength were found to increase

  • Ground Granulated Blast Furnace Slag

    Ground granulated blast furnace slag (GGBFS) is designated in ASTM C 989 and consists mainly of silicates and aluminosilicates of calcium. GGBFS is divided into three classifications based on its activity index.
