GGBFS Ground granulated blast furnace slag (GGBFS) The ground granulated blast furnace slag (GGBFS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree Celsius. The process is carried out in a blast furnace. The formation of GGBFS is not direct. The by-product of iron manufacturing is a molten slag and molten iron. The molten slag consists of alumina and silica, also with the certain amount of oxides. This slag is later granulated by cooling it. For this, it is allowed to pass through a high-pressure water jet. This result in quenching of the particles which results in granules of size lesser than 5mm in diameter. The main constituents of blast furnace slag are CaO, SiO2, Al2O3 and MgO. These are the minerals that are found in most of the cementitious substances. The particles are further dried and ground in a rotating ball mill to form a fine powder, known as ground granulated blast furnace slag cement. Now different methods can be employed to perform the main process called as the quenching. Applications & Benefits of GGBFS: In concrete: The incorporation of ground granulated blast furnace slag in concrete manufacture gains many advantages which are mentioned below: GGBFS in concrete increases the strength and durability of the concrete structure. It reduces voids in concrete hence reducing permeability GGBFS gives a workable mix. It possesses good pumpable and compaction characteristics The structure made of GGBFS constituents help in increasing sulphate attack resistance. The penetration of chloride can be decreased. The heat of hydration is less compared to conventional mix hydration. The alkali-silica reaction is resisted highly. These make the concrete more chemically stable. Gives good surface finish and improves aesthetics. The color is more even and light. Lower chances of efflorescence. The maintenance and repair cost of structures are reduced thus increasing the life cycle of concrete structures. Unlike cement, GGBFS does not produce carbon dioxide, sulphur dioxide or nitrogen oxides. White Cement: White Portland Cement is of high quality, whiteness and strength, it essentially has the same properties and characteristics as gray cement, except for color. It is widely used in numerous applications such as precast concrete, cast-in-place concrete, terrazzo, median barriers, curbs, tile grout, paint, masonry units, swimming pools, glass fibre reinforced surface bonding mortars.

Granulated Blast Furnace Slag : Granulated blast furnace slag or gbfs is the residue of combustion in the furnace of the steel refining process. It is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. Ggbfs or ground granulated blast furnace slag is formed when gbfs is further processed or ground using conventional cement clinker grinding technology. Uses and benefits of GBFS/GGBFS uses : - GGBFS or GBFS is the most used raw material in cement industry to make slag cement. - Lightweight fill - Raw material for the manufacture of glass - GBFS can be used as a substitute for sand in building materials - GGBFS can be used as a replacement for portland cement

Ground Granulated Blast Furnace Slag (GGBFS) is a by-product from the manufacture of Iron and a high-performance substitute to traditional cement that will rise the technical presentation of your application, improve its appearance and minimize its environmental impact. GGBS is used in combination with Portland cement to produce superior longer-lasting concrete. GGBS will improve performance in any situation, from housing to civil engineering applications. GGBFS also improves the concrete toughness, reduces preservation and repair costs, progresses workability and compression features, extensions compressive and flexural strengths, decreases cement and water consumption, advances concrete grading and also improves impermeability and water resistance. Arij Global Trading LLC is a professional Ground Granulated Blast Furnace Slag supplier. We are a global company operating in the fields of the mineral industry, trade, and logistics. Reliable and responsible entrepreneurship, combined with flexibility and innovative logistics solution, plus our motivated and skilled employees, our core proficiencies and efficient work processes, we continuously achieve an above-average value contribution. GGBFS Ground Granulated Blast Furnace Slag (GGBFS) is gained by grounding the Granulated Blast Furnace Slag into the desired fineness. This product is usually intended to be used in concrete either as an element of composite cement such as Blast furnace Cement/High Slag Blast Furnace Cement or as a straight addition to the concrete mix by the concrete producer. GBFS Granulated Blast Furnace Slag GBFS can be used like sand as an additional aggregate for building materials. Granulated Blast Furnace Slag is obtained by quickly chilling (quenching) the molten ash from the furnace with the help of water. Throughout this procedure, the slag becomes fragmented and changed into amorphous granules (glass).
Features Of Granulated Blast Furnace Slag (GBFS) Granulated Blast Furnace Slag or GBFS is formed when Blast Furnace Slag or BFS is successively at a fast rate quenched from the furnace rather than left for cooling. It has a density of about 60% to 70% that of natural sand. This material has a much increased resistance to sulfate attack. This eventually leads to better performance in countering acids of any type. In GBFS, no type of reaction related to alkali and silica occurs. Also the material provides a huge saving in connection to carbon dioxide emission which is an extra boon. What constitutes GBFS are its properties that consist of durability, appearance, higher ultimate strength than concrete which is made up of Portland cement and high sustainability level of the product made out of this material.
