Sika® ViscoCrete®-3300 LS
Sika® ViscoCrete®-3300 LS is a third generation superplasticiser for concrete.
- High water reduction, resulting in high density, high strength and reduced permeability
- Excellent plasticising effect, resulting in improved flow, placing and compaction characteristics
- Reduced shrinkage during curing and reduced creep when hardened
Usage
Sika® ViscoCrete®-3300 LS is a unique multi purpose superplasticiser that is particularly suitable for the production of ready mixed concrete and precast concrete. It provides ultra high water reduction and excellent flow characteristics. With its outstanding combination of workability time and early strength development Sika® ViscoCrete®-3300 LS is used for the following:- A wide range of applications where excellent workability and early strength development are required
- Concrete with ultra high water reduction (up to 30 %)
- High performance concretes
- High strength concrete
- Precast
Advantages
Sika® ViscoCrete®-3300 LS is a powerful superplasticiser based on advanced technology which gives the following advantages:- High water reduction, resulting in high density, high strength and reduced permeability
- Excellent plasticising effect, resulting in improved flow, placing and compaction characteristics
- Reduced shrinkage during curing and reduced creep when hardened
- High flow concrete and long slump retention
- Provides many opportunities for cost improvement, e.g. cement reduction, more economic mix design, reduced energy costs for steam cured precast elements
and prestressed concrete structures.

Important: Always conduct trials before combining products in specific mixes and contact Sika Technical Service Department for information about specific combinations.
DISPENSING
Sika® ViscoCrete®-3300 LS 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 of at least 60 seconds is recommended.
The standard rules of good concreting practice, concerning production and placing, are to be followed.
Laboratory trials before actual 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.
Recommended Dosage
| Medium workability | 0.6–1.0 % by weight of cement |
| High workability | 0.8–1.5 % by weight of cement |
| SCC with high slump retention | 1.0–2.0 % by weight of cement |
