Ground granulated blast-furnace slag - Wikipedia

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. Ground -granulated blast furnace is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing …

Granulated blast furnace slag should contain calcium oxide (CaO), magnesium oxide (MgO), and silicon dioxide (SiO 2), the sum of which should account for at least two-thirds of the mass. The remaining third contains aluminium oxide (Al 2 O 3 ), with small amounts of other compounds.

Blast Furnace Slag - an overview | ScienceDirect Topics

Blast furnace slag (BFS) which is defined “as the non-metallic product consisting essentially of silicates and alumina silicates of calcium and other bases, that is developed in a molten condition simultaneously with iron in a blast furnace” by ASTM C 125-16 (2016) has been widely used in construction industry for more than 80 years. When the mixture of iron-ore, coke, and limestone is …

Blast Furnace Slag - Material Description - User ...

Blast furnace slag is a nonmetallic coproduct produced in the process. It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. The molten slag, which absorbs much of the sulfur from the charge, comprises about 20 percent by mass of iron production.

THE - National Slag

Blast Furnace Slag is defined as the non-metallic product consisting essentially of silicates and alumino-silicates of calcium and other bases that is developed in the molten condition simultaneously with iron in a blast furnace.

Properties of Hardened Concrete with Blast Furnace Slag

Figure-4: Blast Furnace Slag Particles. Permeability of concrete incorporating slag. It is claimed that, concrete incorporating slag perform better in terms of permeability compare with controlled concrete because blast furnace slag in cement paste decreases the size of pores and consequently the permeability of slag concrete is declined.

Fly ash and slag - ScienceDirect

Low-calcium (FA) and high-calcium (HCFA) fly ash and granulated blast furnace slag (GBFS) are the most widely known, standardized and used SCMs in the composition of cement and concrete. In the last 4 years, scientific work has focused on improving binder properties (e.g. long setting time, low early strength etc.) containing large quantities of FA, HCFA and GBFS.

Fertilizers : Iron and steel slag products : NIPPON SLAG ...

Because blast furnace slag contains fertilizer components CaO, SiO 2, and MgO, it is used in rice cultivation as calcium silicate fertilizer. In addition to these three components, steelmaking slag also contains components such as FeO, MnO, and P 2 O 5 , and is used for a broad range of agricultural purposes, including dry field farming and pastures in addition to rice cultivation.

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. The major components of these slags therefore include the oxides of calcium…

Ground Granulated Blast-Furnace Slag: Its Chemistry and ...

Ground granulated blast-furnace slag (GGBFS), sometimes simply referred to as “slag”, is a glassy granular material formed when molten blast-furnace slag is rapidly chilled, as by immersion in water. It is a non-metallic product, consisting of silicates and aluminosilicates of

Effect of basic oxygen furnace slag on succession of the ...

Nov 30, 2019 · In addition, calcium silicate in slag could react with Al 3+ in soil to form stable amorphous hydroxyaluminosilicates and increase soil pH . The conductivity of soil increased after adding slag, which mainly because slag released Ca 2+ , Mg 2+ and other cations in the hydrolysis process ( Yang et al., 2017 ) and these cations exceeded the water-soluble salt ions absorbed by plants.

GGBS - Ground Granulated Blast Furnace Slag for Concrete!

Ground granulated blast furnace slag (GGBS) is a non-metallic product obtained as a byproduct from the blast furnaces used to make iron. Ground granulated blast furnace slag consists of silicates and aluminates of calcium and other bases. The size of its particles is less than 45 microns and specific surface area is about 400 to 600 m 2 /kg.

Two-way Valorization of Blast Furnace Slag: Synthesis of ...

Feb 21, 2017 · 1. Calcium Extraction from Blast Furnace Slag. NOTE: Due to the detrimental effect of acidity on leaching selectivity, the extraction of calcium takes place in two steps, using half the molarity of acetic acid (CH 3 COOH) that would be used in a single step.. Grind the BF slag using a mortar and pestle and sieve it to particle size below 2 mm.

Investigation of Phosphate Removal Capability of Blast ...

May 16, 2019 · Blast Furnace Slag (BFS) is a by-product of iron making with a potential to be used in different applications. In this research, BFS is used to investigate the phosphate removal ability in wastewater. BFS has the required concentrations of surface calcium to potentially precipitate phosphate from wastewater.

Fly Ash, Slag, Silica Fume, and Natural Pozzolans, Chapter 3

SLAG Ground granulated blast-furnace slag (Fig. 3-5), also called slag cement, is made from iron blast-furnace slag; it is a nonmetallic hydraulic cement consisting essentially of sili-cates and aluminosilicates of calcium developed in a molten condition simultaneously with iron in a blast furnace. The molten slag at a temperature of about 1500°C

Effect of ground granulated blast furnace slag on the ...

Dec 10, 2019 · In order to make a good understanding of the properties of calcium sulfoaluminate cement (CSAC) blended with ground granulated blast furnace slag (GGBFS), the effect of GGBFS on the hydration heat, setting time, mechanical strength, pore structure and hydration process of CSAC was investigated using isothermal calorimeter, MIP, XRD, SEM, thermal analysis and so on.
