Sika ViscoCrete-1600 is a third generation superplasticiser for concrete and mortar. It is specially designed for the production of high flow concrete with exceptional flow retention and workability properties.
Sika ViscoCrete-1600 facilitates extreme water reduction, excellent flowability with optimal cohesion and strong self-compacting behaviour making it ideal for the following applications:
The combination of high water reduction, excellent flowability, extended workability, and high early strength provides clear benefits in the above mentioned applications.
Sika ViscoCrete-1600 acts by surface absorption on the cement particles producing a sterical separation effect. Concrete produced with Sika ViscoCrete-1600 exhibits the following properties:
Sika ViscoCrete-1600 does not contain chlorides or other ingredients which promote steel corrosion. Therefore, it may be used without restriction for reinforced and prestressed concrete construction. Sika ViscoCrete-1600 gives the concrete extended workability and depending on the mix design and quality of materials used, self-compacting properties can be maintained for more than 1 hour at 30°C.
