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.
added in calcium aluminate slag, we experimented, in the laboratory phase, the steel treatment with a mechanical mixture consisting of lime, aluminous slag and slag obtained from the titanium making process through the aluminothermic technology. The steel melting was carried out in an induction furnace of 10 kg

Calcium aluminate cements containing blast furnace slag are considered to be used as alternative material. The present study is to discuss the mechanism of sulfuric acid resistance between calcium aluminate cement containing blast furnace slag and ordinary Portland cements. CH and C-S-H were mainly produced in ordinary Portland cement.
Blast furnace slag materials are generally available from slag processors located near iron production centers. Cements containing ground granulated blast furnace slag are available from many producers of Portland cement or directly from ground granulated blast furnace slag cement manufacturers.
Recycling of ladle furnace slags Abstract Ferrous industry slag is waste product of all steelmaking manufactures. These materials should be reused or stocked. There is abundant literature on the subject of reuse and recycling of blast furnace(BF), basic oxygen furnace(BOF), electric arc furnace(EAF).
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
In addition to cement, the inquiry concerns cement-based products (eg ready-mix concrete) and other materials used to produce cement-based products (eg clinker, aggregates, blast-furnace slag, granulated blast-furnace slag, ground granulated blast-furnace slag, etc).
Cemsave is the proprietary name of granulated blast-furnace slag, dry-ground to the same fineness as cement. The Cemsave concrete mixers were chosen so as to be comparable in workability and 28
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.
A surface modification method for blast furnace slag particles is newly proposed to retard the setting time and to mitigate the flow loss in alkali activated slag pastes. BFS particles were treated by a NaOH solution and then were carbonated to modify the surface of the particles.
Blast furnace slag is a byproduct of iron making. For 1000 kg of iron, approximately 290 kg of slag is formed. When the melted slag leaves blast furnace, its temperature is about 1800 K. In Japan, approximately 24 million tons of blast furnace slag is formed annually (1). The heat of melted slag produced annually in Japan is
Calcium Aluminate For Synthetic Slag Applications. BPI produces a range of calcium aluminate products with low melting points for synthetic slag applications primarily in ladle metallurgy operations. We offer complete start to finish ladle practice analysis with recommended synthetic slag additions for metallurgical operations.
Calcium Sulfide 20548-54-3 234-873-5 2-4 EC - European Community CAS - Chemical Abstract Service * The majority of components in Granulated Blast Furnace Slag are various glassy Metallic Silicates (Iron, Calcium, Magnesium, Aluminum, and Titanium Silicates), including:
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.
The following is a brief description of Blast Furnace Slag chemistry and the phenomenon of leaching as it relates to this material. BLAST FURNACE SLAG - Defined 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
The most common process for granulating blast furnace slag involves the use of high water volume, high pressure water jets in direct contact with the molten blast furnace slag at a ratio of approximately 10 to 1 by mass. The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a #4 sieve.
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.
Refractory fused synthetic slag Discription Calcium Aluminate for Metallurgy is a kind of auxiliary material for steelmaking, as it speeds up secondary metallurgy process, especially faster desulphurization, Improves overall steel cleanliness and makes high grade steel with cheaper cost.
