SikaPlast®-5201 NS

HIGH EFFICIENT SUPERPLASTICIZER

SikaPlast®-5201 NS is the latest development of superplasticizer for concrete. It meets the requirements for high range water reducing superplasticizers

SikaPlast®-5201 NS is a powerful superplasticizer 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 plasticizing effect, resulting in improved flow, placing and compaction characteristics
  •  Reduced shrinkage during curing and reduced creep when hardened
  • Water reduction up to 26-35 % depending on dosage*
  • 28 days strength improved by up to 30 %*
* This will depend on dosage and mix design

Application Information

Compatibility

SikaPlast®-5201 NS may be combined with many other Sika® products.

Compatible with all types of cement and cementitious material.

Important: Always conduct trials before combining products in specific mixes and contact our Technical Service Department for information about specific combinations.

DISPENSING

SikaPlast®-5201 NS 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, which is depending on the mixing conditions and mixer performance, of at least 60 seconds is recommended.
To avoid excess water in the concrete, the final dosage must begin only after 2/3 of the wet mixing time.

 
Consumption

Recommended dosage

Standard dosage will vary from 0.2% 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.
