Ground Granulated Blast-Furnace Slag

What Is GGBS ?

GROUND GRANULATED BLAST FURNACE SLAG (GGBS OR GGBFS) Is an Environmentally Friendly Product And Made From A By-Product Of Iron Manufacturing. Ground-Granulated Blast Furnace Slag Is Highly Cementitious And High In Calcium Silicate Hydrates (CSH) Which Is A Strength Enhancing Compound Which Improves The Strength, Durability And Appearance Of The Concrete. Harikrishna Groups Introducing New Green Building Product Known as Ground Granulated Blast Furnace Slag (GGBS / GGBFS).

Applications Of GGBS / GGBFS

For Making Concrete In Construction Site, Manufacturing Of Ready Mix Concrete Units, Manufacturing Of Precast Nature. Roads, Bridges, Tunnels, Retaining Walls, Dams, Canals, Concrete Pipe, Precast Bricks, Precast Walls, Residential & Commercial Constructions, and Other Infrastructure Works. GGBS Is A One Of The Most Important Role In Manufacturing Of Geopolymer Concrete. GGBS Is A Proven Material For Soil Stabilization Globally. All Structural Concrete Applications. (Airport Roads, Bus Stand, Metro & Other Railway Stand) Cement Based Manufacturing Like AAC Blocks, Cement Pipe Roofing Sheets, Solid Block, Hollow Block, Bricks, Wall Putty, Mortar And Other Precast Products.
