Sika Viscocrete 20HE - High Range Water Reducer

Sika Viscocrete 20HE

High early strength superplasticiser

Description

Sika Viscocrete 20HE is a third generation superplasticiser specifically designed for the production of soft plastic concrete with very high early strength characteristics. the special formulation of sika viscocrete® 20 he optimises the dispersion of the binder and at the same time improves the concrete consistency and cohesion.

Uses

Sika Viscocrete 20HE is suitable for the production of concrete mixes which require high early strength development, powerful water reduction and excellent flowability.

• Precast concrete
• Concrete with high water reduction
• High strength concrete
• In situ concrete requiring fast stripping time
• Self compacting concrete (s.c.c)

Advantages

Sika viscocrete® 20 he is an effective superplasticiser, which through surface absorption and sterical effects, the following properties can be achieved:

• Promote high density and impermeable concrete through extreme high water reduction.
• Improves workability and finishability.
• Improves shrinkage and creep behaviour.
• Pronounced increase in the early strength development and set times.
• Higher ultimate strengths.
• Suitable for the production of self compacting concrete.
• Increases the durability of the concrete
• Optimises cement utilization

Sika Viscocrete 20HE does not contain chlorides or other ingredients promoting corrosion of steel reinforcement. it is therefore suitable for reinforced and prestressed steel.
