Granulated blast furnace slag

  • is formed by intensive, rapid water-cooling
  • amorphous
  • hard
  • light coloured
  • glass-like product
  • has good water absorption capacity
  • does not crystallize – due to rapid quenching intensity
  • hydraulic binder property
  • bulk density: 1.1 t/m3
  • homogeneous: 0-5 mm

For cement production, granulated slag as raw material should not be verified with a conformity certification process – in this case, the cement itself is considered to be a construction industry product.
