SikaPlast®-355 X 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®-355 X 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.
Advantages
SikaPlast®-355 X 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
