  • Pavements
  • Hard Stand Areas
  • Carparks
  • Farm Roads
  • Road Shoulder

COMPOSITION AND MATERIALS

SFS530 is produced from steel slag by crushing, screening and processing to remove metals resulting in a 20mm minus steel slag roadbase. Steel furnace slag is a non-metallic product consisting essentially of calcium silicates with fused oxides of iron and aluminium. The material is produced simultaneously with steel in a basic oxygen furnace and is a predominantly crystalline, solid rock-like product.


ADVANTAGES

  • Inherent cementitious properties
  • Interlocking particle shape
  • Well graded
  • High load bearing capacity
  • Lower dust emissions
  • Effective utilisation of an industrial byproduct conserving natural resources
