GGBS 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%). The higher the proportion, the better is durability for concrete. GGBS is also in other forms of concrete including site-batched and pre-cast.

Replacement of Portland Cement by adding up to 70% GGBS, reduce cement content in concrete from about 530 Kg/m3 to 160 Kg/m3 and despite of this large reduction of cement in concrete, ultimate strength is not affected, also considerable improvement in durability properties is observed.

GGBS is used as green construction material.

• High rise building construction
  
• Marine applications such as Dam, Shore protection construction.
  
• Effluent treatment plant
  
• Sewage system construction
  
• Cement products like Pipe, Tiles, Blocks etc.
  
• Substantially replacement of cement.
