The standard rules of good concreting practice, concerning production and placing, are to be followed.
Laboratory trials before concreting on site are strongly recommended when using a new mix design or producing new concrete components. Fresh concrete must be cured properly and as early as possible.

Sika ViscoFlow®-3267 SL may be combined with the following products:

• Plastiment® P121R
• Plastiment® VZ
• Sika® Fume
• SikaFibre®

Do not use viscocrete / viscoflow series combined with sikament series.

To produce flowing and / or self-compacting concrete, special concrete mix design is required.
Pre-trials are recommended and mandatory if combinations with the above products are required.

Please consult to our Technical Service Department.

Sika ViscoFlow®-3267 SL is added to the gauging water or simultaneously poured with it into the concrete mixer. For optimum utilisation of its high water reduction property and slump keeping property, we recommend to add Sika ViscoFlow®-3267 SL into “wet” concrete mixture and then thorough mixing at a minimal wet mixing time of 60 seconds.
The addition of the remaining gauging water (normally 5 % of designed water quantity to fine tune concrete consistency) may only be started after two-thirds of the wet mixing time, to avoid surplus water in the concrete.
When added directly to the freshly mixed concrete, the plasticizing effects is more pronounced.
When accidental overdosing occurs, Sika ViscoFlow®-3267 SL does not entrain excessive amounts of air, however the set retarding effect increases.
