Granulated Blast Furnace Slag (GBFS) - A Key Product In The Cement Industry

Granulated Blast Furnace Slag (GBFS)is a non-metallic co-product thats produced in the process of iron manufacturing. When molten slag is passed through high-volume high-pressure water sprays, a glassy sand-like (granulated) material is formed, known as Granulated Blast Furnace Slag. The color of this co-product is quite similar to that of beach sand. 

Granulated Blast Furnace Slag (or GBFS), when ground into a fine powder is called Ground Granulated Blast Furnace Slag (or GGBS). Ground Granulated Blast Furnace Slag is widely used in the construction industry as a cement replacement to enhance the strength, durability, and life span of concrete structures. 

The applications of Granulated Blast Furnace Slag (GBFS) include:
 

• Slag Cement
• Glass manufacturing
• Trace elements in agriculture
• Concrete block manufacturing
• Reinforced earth embankments
• Sporting field sub-base (for drainage)
• Filtration medium
• Mine backfilling

• Foundations, Piles, Underground Structures, Aqueducts, Canals, Culverts, and Flyovers
• Multi-storied building construction
• Pre-cast concrete
• Mass concreting project works like Dams, Bridges, and Barrages
• Structures in swamp areas and footings, Plinth beams, etc. 
• Water tanks and other water retaining structures
• Construction in coastal areas and saline areas

• Higher ultimate strength
• Improved durability
• Lower permeability of concrete 
• Higher resistance to salts and aggressive/ toxic environment
• Reduced chloride-related corrosion of reinforcement
• Lower heat of hydration
• Better aesthetics 
• Greatly reduced carbon dioxide emissions
• Lower overall costs
