SikaPlast®-2004 NS

Water reducing and set retarding concrete admixture

SikaPlast®-2004 NS is the latest development of superplasticizer for concrete. It meets the requirements for high range water reducing superplasticizers.

SikaPlast®-2004 NS is a powerful superplasticiser based on advanced technology which gives the following advantages:
  • Strong water reduction, resulting in high density and high strength
  • Improved water tightness
  • Less sensitive against variations in aggregates and / or different cement types
  • High efficiency even at low dosage rates
  • Extended workability in conjunction with subsequent strength development
  • Superior plasticising effect, resulting in improved flow, placing and compaction characteristics
  • Water reduction up to 20-30 % depending on dosage*
  • 28 days strength improved by up to 30 %*
    * This will depend on dosage and mix design

Application Information

Compatibility

SikaPlast®-2004 NS may be combined with many other Sika® products.

Compatible with all types of cements and cementitious materials.

Important: Always conduct trials before combining products in specific mixes and combinations. Compatible with all types of cement and cementitious materials.

DISPENSING

SikaPlast®-2004 NS can be added into the mixing water or directly into the concrete mixer after 50 – 70% of the mixing water has been added.

The addition of SikaPlast®-2004 NS to dry aggregate or cement is not recommended.

To achieve optimum performance a minimum wet mixing time, which is depending on the mixing conditions and the mixer performance, of 60 seconds is recommended.
Consumption

Recommended Dosage

Standard dosage will vary from 0.5% to 1.5% by weight of cement. Exact dosage rates are dependent on the quality of cement, aggregates,
water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.
Higher dosage may be used if agreed by engineer and consultant.
Stir well before use.
