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)
GREENPRO GREEN PRODUCT CERTIFICATION
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.

Higher compressive strength
Reduces permeability and thereby enhances durability of the concrete structure
Reduces carbon footprint
Reduces sulphate, chloride, alkali-silica and thermal cracks
Reduces voids in concrete hence reducing permeability
Possesses good pumpable and compaction characteristics
