- hardness of blast furnace slag
Granulated Blast furnace slag (GBS) is a light coloured 0/4mm glassy sand produced by the rapid quenching of molten blast furnace slag using large volumes of water. Production and Processing . GBS or Granulate as it is sometimes known is produced by rapidly cooling molten Blast furnace slag with water as the slag is tapped from the furnace.

Blast furnace slag particles (BFSP), generated in large quantities during steel manufacture, consisting of SiO 2 and Al 2 O 3, have been used to develop glass fiber (GF) and blast furnace slag particles (BFSP) reinforced epoxy based hybrid composites by hand lay-up. The composites exhibit improved hardness,
Jan 10, 2014· Slags are one of the most natural products of all. Slags are principally divided into blast furnace slag and metallurgical slag. At voestalpine the slags resulting from the steelmaking process are separated into blast furnace and metallurgical slags and then recycled. The separated slags are processed into valuable products.

Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace.
blast furnace slag. Grading Expanded blast furnace slag is crushed and screened to desired product sizing. Typically this is a blend of coarse and fine aggregate particles. The actual grading of products should be reviewed with the local supplier. The Process In the pelletizing process, a molten blast furnace slag stream is directed onto an ...
Iron (Blast Furnace) Slag Blast furnace slag is often used when maximum durability, higher strength, hardness of aggregate, fire resistance, better insulation and lighter weight are required. The shape and texture of blast furnace slag promote excellent bonding with cement mortar. Blast furnace slags can be used as aggregates although they
Changes in coke hardness affect the working of the blast furnace, for soft coke is an obstacle to proper furnace operation. Soft coke is due to a low hydrogen-oxygen ratio in the coal charged; increasing this ratio increases the hardness of the coke.
The blast furnace slag powder (Iron & Steel Company, Shandong Province, China) and the fluorite tailings (Jiangxi Province, China) were used as starting materials for parent glass formation. With respect to the selected basic composition of parent glasses (), additional 3 wt% P 2 O 5 was incorporated.

Blast furnace slag is the one major byproduct of pig iron production, regularly generated each year in signifi-cant volumes as thousands of tons. Granulated blast furnace slag (GBF slag) is obtained by quenching molten iron slag (a byproduct of iron making) from a blast furnace in water or steam, to produce a glassy, granular product.
Blast Furnace Steel Slag Blast Furnace Slag % Ground Granulated Blast Furnace Slag (Ger.) % Ground Granulated Blast Furnace Slag (UK) % Basic Oxygen Furnace Slag % Electric Arc Furnace Slag % Calcium Oxide (CaO) 32 to 45 39.2 40 43 35 ... Hardness (Moh's) 5 to 6 6 to 7 . 15 .
We prepared four slabs using blast furnace slag powder of various percentages i.e. 0%, 5%, 10% and 15%), for first slab preparation blast furnace slag is 0%, so only epoxy and hardener mixture is placed in between the two successive layers. Based on the weight of nil (0%) slab, 5% blast furnace slag is calculated and added for next slab.
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 - 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.
May 09, 2018· Ground Granulated Blast Furnace Slag (GGBS) The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs proper method for disposal. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components such as cement, fine …
PDF | In this paper, blast furnace slag was investigated as a source of the basic Si-Al ingredient of geopolymer. On the basis of compressive strength, the effects of grinding time on the activity ...
Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.
The vast quantity of blast-furnace slags pro-duced in Brazil and the successful conversion of these materials into glass-ceramics in other coun-tries [3,4] were the main reasons this study was undertaken. Properties such as high strength, hardness and wear resistance have allowed slag glass-ceramics to be used successfully in several
1.2 Fibre (Blast Furnace Slag) Ground granulated blast furnace slag (GGBFS) is a by-product from the blast furnaces used to make iron. When blast furnace is fed with proportionate mixture of iron-ore, coke and limestone and operated at the temperatures of about 15000C, molten iron and molten slag is formed. Molten slag being lighter than molten ...
* The majority of components in Granulated Blast Furnace Slag are various glassy Metallic Silicates (Iron, Calcium, Magnesium, Aluminum, and Titanium Silicates), including: Dicalcium Silicate (Ca2SiO4) 14284-23-2, Merwinite (Ca3MgSi2O8) 13813-64-4, and Gehlenite (Ca2Al2SiO7) 1302-56-3.

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.
What is the hardness of slag coal? ... Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted ...
Mohs' Hardness (Typical) of Abrasives table from READE. Abrasive blasting for surface preparation is an important step in providing a foundation for protective coatings. For years, tests have concluded that high-performance coatings provide excellent corrosion protection and durability when applied over a blast-cleaned surface with a consistent anchor profile.
