SikaPlast-5201 NS

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.

Advantages

SikaPlast®-5201 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
