SikaPlast®-5202 NS

Retarding Superplasticizing Admixture

SikaPlast®-5202 NS is the latest development of superplasticizer for concrete. It meets the requirements for high range water reducing superplasticizers.

SikaPlast®-5202 NS is a powerful superplasticiser based on advanced technology which gives the following advantages:
  • Strong water reduction, resulting in high density, high strength and reduced permeability
  • 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
  • Reduced shrinkage during curing and reduced creep when hardened
  • Provides many opportunities for cost improvement

Application Information

Compatibility

SikaPlast®-5202 NS may be combined with many other Sika®  products.

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

DISPENSING

SikaPlast®-5202 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®-5202 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

0.5% to 2.0% by weight of cementitious. Higher dosage may be used if agreed by engineer and consultant

Actual dosage to be finalised on the basis of site trials. Stir well before use.
