Current applications

  • Reinforced concrete for in-ground and above-ground works requiring good final strength
  • Concrete for foundations and works in aggressive environments
  • Concrete in contact with seawater
  • Concrete for massive pours requiring the controlled development of the heat of hydration
  • Concrete for road and rail works, including paving
  • Wet-process sprayed concrete for tunnel linings
  • Sewage works
