Sika Viscocrete® SP1000 is a 3 generation polymer based high performance superplasticizer with hardening acceleration effect for concrete. Sika Viscocrete® SP1000 increases the development of concrete early strength. Sika Viscocrete® SP1000 meets requrement of ASTM C494 type F & G

Sika Viscocrete® SP1000 is mainly suitable for the manufacture of concrete in precast factories. Sika Viscocrete® SP1000 excels by its extremely high water reduction capacity, providing good flowability while retaining optimal cohesion of the mix. Sika Viscocrete® SP1000 is used for the following types of concrete:

High-strength/High performance concrete spun pile in precast industry.

Concrete with extreme water reduction

Self-Compacting-Concrete in precast industry

Sika Viscocrete® SP1000 combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, Sika Viscocrete® SP1000 effects the following concrete properties:

- Extremely high water reduction (Producing high impermeability and strengths)

- High flowability (considerably reduced placing and compacting work)

- Faster evolution of early strength development. Can reduce the time of steam curing process for getting early strength.

- Workability can be maintained up to 60 minutes (still depends on cement type, temperature and mix design)

- Highly improved waterproofness.

- Improved creep and shrinkage resistance characteristics.

Sika Viscocrete® SP1000 contains neither chlorides nor other corrosion-inducing subsances and can therefore be used without any restrictions for reinforced and prestressed concrete structures

Dosage: 0.50 - 2.0 ltr. per 100 kg of cement

Typical Dosage: For soft/plastic concrete 0.5 - 0.9 ltr per 100 kg of cement

For spun pile 0.6 - 0.9 ltr per 100 kg of cement

For SCC concrete: 0.9 - 2.0 ltr. per 100 kg of cement

Compatibility: Sika Viscocret®SP1000 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 Viscocre® SP1000 is compatible with all Portland Cement types.

Addition/Mixing: Sika Viscocret® SP1000 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 Viscocret® SP1000, 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
