Specification of Admixture Sika ViscoCrete 3115 N
DESCRIPTION
Ready Mix Beton Sika ViscoCrete-3115N is a third-generation superplasticiser for concrete and mortar. It is particularly developed for the production of high flow concrete with exceptional flow retention properties.
USES
Sika ViscoCrete-3115N facilitates extreme water reduction, excellent flowability with optimal cohesion and strong self-compacting behaviour.
Sika ViscoCrete-3115N is used for the following types of concrete :
- High flow concrete
- Self-compacting concrete (S.C.C)
- Concrete with very high water reduction (up to 30%)
- High strength concrete
- Watertight Concrete
- Precast Concrete
- The combination of high water reduction , excellent flowability and high early strength provides clear benefits in the above mentioned applications.
CHARACTERISTICS AND ADVANTAGES
- Sika ViscoCrete-3115N acts by surface adsorption on the cement particles producing a sterical separation effects. Concrete produced with Sika ViscoCrete-3115 N exhibits the following properties:
- Excellent flowability
- Strong self-compacting behaviour
- Extremely high water reduction
- Improved shrinkage and creep behaviour
- Increased carbonation resistance of the concrete
- Improved finish
- Sika ViscoCrete-3115N does not contain chlorides or other ingredients which promotes steel corrosion. Therefore, it may used without restriction for reinforced and pre-stressed concrete construction.
- Sika ViscoCrete-3115N gives the concrete extended workability and depending on the mix design and the quality of materials used, self-compacting properties can be maintained for more than 1 hour at 30°C.
