High strength concrete enhanced with silica fume provides architects and engineers with greater design flexibility. Traditionally used in high-rise buildings for the benefit of smaller columns (increasing the usable space) high-strength concrete containing silica fume is often used in precast and prestressed girders allowing longer spans in structural bridge designs.

Key advantages include: -

  • Very low permeability to chloride and water intrusion
  • Extremely high electrical resistivity (20 to 100 times greater than ordinary concrete).
  • Increased abrasion resistance on decks, floors, overlays and marine structures.
  • Superior resistance to chemical attack from chlorides, acids, nitrates and sulfates.
