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.

Blast Furnace Slag is a by-product of the manufacturing of steel in a blast furnace. Initially, in its molten form, it is diverted to a granulator where it is quenched with water and rapidly cooled to form glassy, non-metallic granules which are silicates and aluminosilicates of calcium. These granules are dried to produce Granulated Blast Furnace Slag (GBFS) and then ground to a suitable fineness to produce Ground Granulated Blast Furnace Slag (GGBFS). When used as a cementitious material in concrete, GGBFS enhances long-term performance and durability characteristics while reducing life-cycle and maintenance costs.
ggbfs or steel slag
Our plant has four GGBFS production lines, adopting the imported LM56.3+3S large scale slag three-roller mill equipment. Four lines designed annual production is 4.8 million tons with the 450m2/kg fineness. The GGBFS S75, S95, S105 conform to the GB/T18046-2000 standard and UK BS6699 standard. Remarkable effectiveness: 1. It can economize the 30-70% cement dosage (including the cement plaster) and reduce the concrete cost, every cubic meters of concrete comprehensive cost can be reduced on average about 10-23rmb. 2. It can lower the bleeding and improve the concrete workability. 3. It can significantly reduce the concrete heat of hydration, improve concrete workability, reduce the liquating and bleeding and the massive concrete temperature change and internal stress, especially suitable for massive concrete preparation. 4. It exists in the concrete as cementitious material and can improve the concrete pore structure with the aperture be refined and homogenization, as well as can improve the concrete anti-permeability, the resistance of freezing and thawing and durability. 5. Effectively improve concrete seawater and fresh water resistance corrosion performance, and resist sulphate erosion. Especially it is suitable for resistance seawater, underground and surface engineering. 6. It significantly improves the concrete alkali-resistance aggregate reaction ability. 7. Increase the concrete strength of anti-press, anti-pulling, anti-bending and sheering, easily make up the high strength concrete. 8. Under the condition of invariable water, it can make up the plastic concrete, in order to avoid the quality problem due to the intensive steel bar and poor vibrating. 9. Under the condition of invariable in water, it can make the concrete into the mold as the liquid, and reduce the wear and tear of concrete pump body, pipeline and mould, then prolong its working life. 10. Can make up masonry, plastering cement plaster and low grade cement. Under the situation of meeting the strength requirements, not only it can save 30-70% cement, meanwhile can improve the construction operability. 11. It can be used in fabrication of environmental compatibility type of cement base material and high performance concrete admixture.
