GGBS . GGBS Ground Granulated Blast Furnace Slag is a fine powder, used in concrete as "cement", major use in ready mixed concrete (RMC) or in the production of Portland slag cement. GGBS replaces a substantial proportion of normal cement (Ordinary Portland Cement) in RMC. The mixing varies from 30% to 70% approximately (generally 50%).

A successfully running plant of GGBS (Ground Granulated Blastfurnace Slag) since 2011 is available for sale in Karnataka. It is a running plant doing slag grinding and producing GGBS powder which is used in ready to mix concrete plants. Granulated blast furnace slag is a by product of steel plants, granulation is done by quenching with water.
