Sika® Viscocrete 3000 is a 3 generation polymer based high performances superplasticizer for producing soft consistency concrete suitable for pumping. Sika® Viscocrete 3000 meets the requirements of ASTM C 494 Type G

Sika®Viscocrete 3000 is mainly suitable for the manufacture of con-crete for RMC and precast batching plants. Sika® Viscocrete 3000 excels by its extremely high water reduction ca-pacity, providing good flow ability while retaining optimal cohesion of the mix. Sika ® Viscocrete 3000 is used for the following types of concrete:

- High-strength/ High performance cast on site concrete.

- High strength bored piles

- Bridges and cantilever

- Slender components with dense reinforcement

Sika® Viscocrete 3000 combines different modes of actions. By adsorp-tion on the surface of the fine cement grains and keeping them apart while the hydration is in progress, Sika®Viscocrete 3000 effects the following concrete properties:

- Extremely high water reduction.

- Producing soft consistency and suitable for pumping.

- High flowability (considerably reduced placing and compacting work)

- Workability can be maintained up to 90 minutes (still depends on admixture dosage, cement type, temperature).

- Improved creep and shrinkage resistance characteristics.

Sika® Viscocrete 3000 contains neither chlorides nor other corrosion-inducing substances and can therefore be used without any restrictions for reinforced and prestressed concrete structures.

Dosage: 0.8 - 2.0 ltr per 100 kg of cement/Cementitious (Range)

Typical Dosage: 1.0 - 1.5 ltr per 100 kg of cement/Cementitious (Typical)

Compatibility: Sika® Viscocrete 3000 may be combined with all Sikament, Sika Aer, Sika Pump, Sikacrete PP1 products, but must be added separately to the mix and not pre-mixed prior its addition. Sika® Viscocrete 3000 is compatible with all Cement types.

Addition/Mixing: Sika® Viscocrete 3000 is added to the gauging water prior to its addition to the dry mix or added separately to the wetted concrete mix. For optimum utilisation of the ultra high range water reducer we recommend a minimum wet mixing time of 60 seconds. When adding the balance of the batching water to adjust concrete consistency this should be done after a minimum of 2/3 of the wet mixing time to avoid surplus water in the concrete.

Concrete Placing: With the use of Sika® Viscocrete 3000, concrete of highest quality is being produced, however state of the art Concrete technology, such as mixing, placing vibrating and curing must be respected and applied.
