Ground Granulated Blast Furnace Slag GGBS 1. Packageing & Delivery Packing details: 1000 kg/bag or In bulk Delivery Details: 30 days after receiving your 30% deposit or L/C 2. Product Description: The Ground Granulated Blast Furnace Slag (GGBS) is a type of eco-friendly green building material and high quality secondary cementitious material for concrete and cement. It is recognized as one of the best secondary cementitious material for building high durable concrete strecture in the world today !GGBS has taken over top place of high-performance cement and concrete mineral additives with its unique characteristics of hydration,low-price raw material.GGBS is obtained by quenching molten iron blastfurnace slag (a by- product of iron and steel making) in water or steam. It is then further grounded into the desired fineness in terms of the required particle size distributionm. 3. Applications & Benefits For the product: ?, Super-reactive cementitious additives, especially suitable for:A. Production of medium content (30-50%) slag cement, improving the strength of all ages.B.
