Sika® ViscoCrete®-5002 N

HIGH PERFORMANCE SUPERPLASTICISER

Sika® ViscoCrete®-5002 N is a third generation superplasticiser for concrete and mortar and designed for used as high range water reducing superplasticisers.

Sika® ViscoCrete®-5002 N is an economical superplasticiser based on advanced technology which gives the following advantages :
  • High water reduction, resulting in high density, high strength and reduced permeability.
  • Extended workability in conjunction with subsequent fast strength development.
  • Excellent plasticising effect, resulting in improved flow, placing and compaction characteristics.
  • Reduced shrinkage during curing and reduced creep when hardened.
  • Provides many opportunities for cost improvement e.g.: Cement reduction, More economic mix design, Reduced energy costs for steam curing precast elements, Reduction of potential claims etc.
Sika® ViscoCrete®-5002 N does not contain chlorides or any other ingredients which promote the corrosion of steel. It is therefore suitable for use in reinforced and prestressed concrete structures.

Concreting guidance

The standard rules of good concreting practice, concerning production and placing, are to be followed.

Laboratory trials before concreting on site are strongly recommended when using a new mix design or producing new concrete components.

Fresh concrete must be cured properly and as early as possible.

Application

Compatibility

Sika® ViscoCrete®-5002 N may be combined with the following products:

  • Plastiment® P121R
  • Plastiment® VZ
  • Sika® Fume
  • SikaFibre®

Do not use viscocrete / viscoflow series combined with sikament series.

To produce flowing and / or self-compacting concrete, special concrete mix design is required.

Pre-trials are recommended and mandatory if combinations with the above products are required.

Please consult to our Technical Service Department.

DISPENSING

Sika® ViscoCrete®-5002 N is added to the gauging water or added with it into the concrete mixer.

To take advantage of the high water reduction, a wet mixing time of at least 60 seconds is recommended.

Recommended dosage

For medium workability :0.6 % - 1.0 % by weight of binder
For concrete with high workability, very low water/cement ratio :1.1 % - 2.0 % by weight of binder
