SikaPlast®-5203 NS

High efficient superplasticizer

SikaPlast®-5203 NS is the latest development of superplasticizer for concrete. It meets the requirements for high range water reducing superplasticizers

SikaPlast®-5203 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

Application

Application Information

Compatibility

SikaPlast®-5203 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®-5203 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

0.2 % to 2.0 b. w. o. c. Optimum dosage has to be finalized through site trials. And also if any Air entraining admixture is used separately then the dosage should be adjusted by site trial. Stir well before use.
