Sika ViscoFlow®-3300

HIGH RANGE WATER REDUCING CONCRETE ADMIXTURE WITH ENHANCED WORKBILITY RETENTION

Sika ViscoFlow®-3300 is a 3rd generation polymer based high performance superplasticizer for producing soft consistency concrete. It is particularly suited for use in concretes that require low water/cement ratios and / or high water reductions with excellent workability retention properties of up to 3 hours.
Sika ViscoFlow®-3300 meets the requirements of ASTM C 494 type D & G.

Sika ViscoFlow®-3300 combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, Sika ViscoFlow®-3300 effects the following concrete properties:
  • Extended consistence retention;
  • Improved cohesion properties;
  • Improved early and ultimate strengths;
  • Excellent placement characteristics;
  • Improved rheology;
  • Improved durability;
  • Reduced segregation and bleeding;
  • Reduced drying shrinkage.
Sika ViscoFlow®-3300 contains neither chlorides nor other corrosion inducing substances and can therefore be used without any restrictions for reinforced
concrete structures.

Usage

Sika ViscoFlow®-3300 is mainly suitable for the manufacture of concrete for RMC plants and site batch concrete.
Sika ViscoFlow®-3300 is used for the following types of concrete:
  • Applications that require extended consistence retention without delayed setting;
  • Suitability for use across broad range of consistence classes from S4 – SF3;
  • High performance concrete;
  • Self compacting concrete;
  • High rise/pumped concrete;
  • Slip form concrete;
  • Improved effectiveness in higher ambient temperatures.

Technical Information

Concreting Guidance

Concrete placing: With the use of Sika ViscoFlow®-3300, concrete of highest quality is being produced, however state of the art concrete technology, such as mixing, placing, vibrating and curing must be respected and applied.
Curing: Effective measures for concrete curing must be followed.

Specific Advice

Sika ViscoFlow®-3300 is added to the gauging water prior to its addition to the dry mix or added separately to the wetted concrete mix.
For optimum utilization of the ultra-high range water reducer we recommend a minimum wet mixing time of 60 seconds.
When adding the balance of the batching water to adjust concrete consistency this should be done after a minimum of 2/3 of the wet mixing time to avoid surplus water in the concrete.

Application

Application Information

Compatibility

Sika ViscoFlow®-3300 may be combined with all Sikament, Sika® Aer, Sika® Pump, Sikacrete® PP-1 products, but must be added separately to the mix and not premixed prior its addition.
Sika ViscoFlow®-3300 is compatible with all Portland cement types.
