Product Code GBF004

ASMS GBF004 Masonry Grade Granulate is a coarse sand-like material with a porous, amorphous structure ranging from white to golden brown in colour.


APPLICATIONS

GBF004 is suitable for use in a range of manufacturing and civil applications including:

  • Block making
  • Roadbase stabilisation
  • Water treatment


COMPOSITION AND MATERIALS

GBF004 is a glassy, granular material produced by granulating blast furnace slag.

Blast furnace slag is the non-metallic product consisting essentially of silicates and aluminosilicates of calcium and other bases developed in a molten condition simultaneously with iron in a blast furnace.

Molten slag is passed through high volume water sprays which break the slag stream into small droplets which are rapidly quenched, suppressing crystallisation and resulting in a material with a porous, amorphous structure.


ADVANTAGES 

  • Consistent chemistry
  • Cementitious properties
  • Low iron levels
  • Bright colour
  • Low chloride content

ENVIRONMENTAL VALUE

  • Effective utilisation of an industrial by-product
  • Conserves natural resources and preserves natural landscape
  • Reduces the need for landfill sites
  • Reduces greenhouse gas emissions
