Engineered for Durability and Long-Term Performance

Ground Granulated Blast Furnace Slag (GGBFS) is a hydraulic cementitious material produced by drying and finely grinding granulated blast furnace slag. It has been used in concrete construction for over a century and is widely recognized for its ability to enhance durability, performance stability, and lifecycle cost efficiency in modern concrete design.

By partially replacing Portland cement, GGBFS improves concrete performance while reducing long-term maintenance requirements.

Key Performance Benefits

When used as a cement replacement or concrete admixture, GGBFS provides:

  • Improved workability and easier placement

  • Higher long-term compressive and flexural strength

  • Lower permeability and enhanced durability

  • Improved resistance to chemical attack

  • Reduced heat of hydration and cracking risk

  • More stable plastic and hardened concrete behavior

  • Lighter concrete color and improved surface appearance
