JSW PSC replaces some portion of OPC with Ground Granulated Blast Furnace Slag (GGBFS), whose secondary hydration produces more C-S-H gel and improves concrete performance. It is produced with a roller press and vertical roller mill so fineness and microstructure can be controlled for consistent quality. The brochure positions it as an all-purpose cement and notes IS 456 recommends PSC for stronger and more durable construction; its use adds points towards green building certification (LEED, CII, IGBC).

Key features

• Better surface for painting
• Incomparable long-term strength
• Reduced thermal cracks due to lower heat of hydration vs OPC
• Reduced shrinkage cracks vs OPC, PPC
• Improved workability and smooth finish
• Improved cohesion
• Better resistance against chlorides, sulphates and carbon dioxide
• Improved durability
• Green product
• Higher flexural strength
• Concrete strength keeps increasing beyond 28 days versus OPC and fly ash concrete

Applications

• Residential, commercial and industrial complexes
• Concrete roads and flyovers
• Mass concrete works
• Dams and foundation/subsoil works
• Pile construction
• Water retaining structures
• Marine works
• Effluent treatment plants
• High-rise buildings
• Metro
• All civil, structural and non-structural works
