SikaFume®-50 S (GB)

Silica Fume Slurry Admixture for High Performance Concrete

SikaFume®-50 S (GB) is a modified concrete additive in liquid form based on Sika® silica fume / microsilica technology. It is a formulated blend of highly reactive pozzolanic materials and stabilisers designed to produce high quality concrete. SikaFume®-50 S (GB) is particularly suitable for chemical resistance, exposure to aggressive atmospheres, abrasion and high strength mixes. It should always be used in conjunction with a superplasticiser from the Sika range, or equivalent, subject to trials.

SikaFume®-50 S (GB) improves properties of the fresh concrete, such as cohesion, bond and water efficiency. In hardened concretethe highly active pozzolanic material reacts with the free lime produced by the hydration of the cement to improve the strength, density and durability of the concrete.  SikaFume®-50 S (GB) enhances the following characteristics:
  • Cohesion
  • Early and final strength
  • Impermeability to liquids and gases
  • Chloride, sulfate and acid resistance
  • Resistance to alkali-silica reaction in aggregates
  • Resistance to freeze/thaw cycles and abrasion
