Ground Granulated Blast Furnace Slag

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

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.

Ground Granulated Blast Furnace Slag plays a vital role in making stronger and durable concrete structures and is among the most sustainable building materials in India. Tata Steel GGBS has been awarded the Green Pro Certification for being a sustainable building material.

GreenPro Green Product Certification

Awarded "GreenPro" Certification by CII-Godrej GBC.

Tata Steel is one of the first organizations 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.
