Ground Granulated Blast Furnace Slag

Ground Granulated Blast Furnace Slag or GGBS, is one of the most sought after sustainable and eco-friendly building materials in India as well as across the world. Tata Steel is one of the leading GGBS manufacturers in India offering premium quality product.

All over the world, GGBS is used as an eco-friendly building material because it is a perfect replacement of OPC Cement. Buildings and structures made from GGBS as a replacement of OPC cement are far more durable and offer unmatched strength.

The inherent properties of GGBS make it the first choice for builders looking at strong, durable as well as environment-friendly building material for their projects. GGBS from the Industrial By-Product Managament Division (IBMD) of Tata Steel has been used as a replacement of OPC cement in construction of many iconic structures across India such as the renowned Ganga Setu Bridge, Vrindavan Chandrodaya Mandir, Garden Reach Flyover Project, Kalyani Expressway among others.

Tata Steel, one of the acclaimed GGBS manufacturers in India, has earned another feather in its cap with its GGBS being awarded the ‘Green Pro Certification’ for its varied applications, and usage as a long-lasting and viable eco-friendly building material in India. The product, apart from offering environmental benefits, is also cost effective.


Ground-granulated blast-furnace slag (GGBS) is a supplementary cementitious material used in concrete and is produced by drying & grinding of Granulated blast furnace slag into a fine powder.

GGBS’s intrinsic properties contribute towards manufacturing sustainable concrete with higher compressive strength, reduced permeability & resistance to chloride and Sulphate attacks.

Physical Properties of GGBS:

  • State: Fine Powder
  • Dimensions: ~4000 cm2/gm (Blaine)
  • Color: Whitish


Awarded "GreenPro" Certification by CII-Godrej GBC.

Tata Steel has earned its name as one of the leading GGBS manufacturers in India and holds a prominent place among the eco-friendly building materials suppliers in India.

GGBS is one the most preferred eco-friendly building materials in construction of high-rise buildings, marine applications such as dams, shore protection structures, effluent and sewage treatment plants both in India and across the world.
