Sika ViscoFlow®-1994 NG

High Range Water Reducer / Superplasticizer Concrete Admixture

Sika ViscoFlow® 1994 is an improved, new generation, non-chlorinated, acrylic
copolymer superplasticizer / high-range water-reducing and slump-retaining
admixture.

ViscoFlow® 1994 combines several actions. Adsorption to the surface and
separation of fines particles by steric hindrance during the hydration process give
the following properties:
  •  Extended workability.
  •  High water reduction (consequently high waterproofing and resistances).
  •  High fluidity (consequently easier application).
  •  High short term resistance.
  •  High waterproofing improvement.
  •  Better creeps and shrinkage behaviour.
  •  Lower carbonation speed.
ViscoFlow® 1994 does not contain any chloride or other component which could
cause or increase steel corrosion. It can be used without restriction for reinforced or
prestressed concrete constructions

Usage

Sika ViscoFlow® 1994 is used for concrete in precast plants, on site and for ready
mix concrete. ViscoFlow® 1994 is used for concrete that need to be transported over
long distance or with extended application time.
ViscoFlow® 1994 is added for production of:
  • Plastic to fluid concrete.
  • Low W/C ratio concrete with or without silica fume.
  • Concrete with high water reduction (up to 35%) and improved strength.
  • Concrete with air entraining
