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.
