Fine slag powder

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.
