Ground Granulated Blast Furnace Slag

Ground Granulated Blast Furnace Slag (GGBS) is obtained by grinding blast furnace slag in water or steam

GGBS, Ground Granulated Blast Furnace Slag, is one of the most sought after sustainable building materials in India. Tata Steel IBMD is one of the leading suppliers of GGBS and the product has been used in construction of many iconic structures in India.

The Ground Granulated Blast Furnace Slag (GGBS) is obtained by grinding blast furnace slag in water or steam. This process leads to a glassy, granular product that is then dried and ground into a fine powder. GGBS offers a more sustainable concrete having higher compressive strength, reduced permeability and resistance to chloride and sulphate attacks.

Tata Steel GGBS has been awarded the Green Pro Certification for its varied applications, and usage as a sustainable building material. The product, apart from offering environmental benefits, also helps in cost saving, and leads to durable constructions.

GreenPro Green Product Certification

Awarded "GreenPro" Certification by CII-Godrej GBC.

Tata Steel IBMD is among the first among the GGBS Suppliers in India to have received this prestigious accreditation for its sustainable eco-friendly GGBS.

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

Spinnaker Tower (UK) - 50% GGBS
Tsing Ma Bridge (Hong Kong) - 60-70% GGBS
Three Gorges Dam (China) - 40% GGBS
Georgia Aquarium (USA) - 20-70% GGBS
Hangzhou Bay Bridge (China) - 40% GGBS

Ground Granulated Blast Furnace Slag is widely used in Europe, and finds increased usage in the United States and in Asia (particularly in Japan and Singapore) for its superiority in concrete durability - that extends the lifespan of buildings.
