GGBS

Granulated Blast Furnace Slag is obtained by rapidly chilling (quenching) the molten ash from the furnace with the help of water. During this process, the slag gets fragmented and transformed into amorphous granules (glass), meeting the requirement of IS 12089:1987 (manufacturing specification for granulated slag used in Portland Slag Cement). The granulated slag is ground to desired fineness for producing GGBS.

CHARACTERISTICS OF GGBS

Consistent Quality

High Durability

Sustainable

Value for Money

Advantages with GGBS

  • Reduces the temperature rise and helps to avoid early-age thermal cracking

  • Improved workability

  • High resistance to chloride penetration

  • High resistance to sulphate attack

  • It is off-white in color and substantially lighter than Portland Cement. Resultantly it helps soften the visual impact of a large structure as bridges and retaining walls.

Replacement in Concrete

  • Replacement rates for GGBS vary form 30% to upto 70%.

  • Higher replacement rates up to 70% are used in specialist applications such as in aggressive environment and to reduce the heat of hydration
