Sika Viscocrete HE - 10AT is a 3 generation polymer based high perfor-mance superplasticizer. Sika Viscocrete HE-10AT meets the requirements of ASTM C494 Type F & G.

Sika Viscocrete HE - 10AT is a multipurpose admixture for the manufac-ture of high performances pre-cast and cast-on-site concretes. Sika Viscocrete HE-10AT excels by its extremely high water reduction capacity, providing good flowability while retaining optimal cohesion of the mix. Sika Viscocrete HE-10AT is used for the following types of concrete:

- High-strength/High performance concrete.

- Concrete with extreme water reduction

- Self-Compacting-Concrete in precast industry

Sika Viscocrete HE-10 combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, Sika ViscocreteHE-10 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.

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

- Improved creep and shrinkage resistance characteristics.

Sika Viscocrete HE-10 contains neither chlorides nor other corrosion - inducing subsances and can therefore be used without any restrictions for reinforced and prestressed concrete structures.

Dosage: 0.5 - 2.0 ltr. per 100 kg of cement

Typical Dosage: For soft/plastic concrete 0.5 - 0.8 ltr per 100 kg of cement

For SCC concrete: 0.9 - 1.8 ltr. per 100 kg of cement.

Compatibility: Sika Viscocrete HE-10AT 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 HE-10AT is compatible with all Portland Cement types.

Addition/Mixing: Sika Viscocrete HE-10AT is added to the gauging water prior to its addi-tion to the dry mix or added separately to the wetted concrete mix. For optimum utilisation of the ultra high range water reducer we recom-mend a minimum wet mixing time of 60 seconds. When adding the balance of the batching water to adjust concrete consis-tency 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 HE-10AT, 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
