Special Features:

Workability is greatly improved

Increased placeability in slender components with packed

reinforcements

Sikament NN is a highly effective dual action liquid as superplasticizer for the production of flowable concrete and as a substantial water-reducing agent for promoting high early and ultimate strength.

Sikament NN complies with ASTM C494 Type F.

Sikament NN is used as a superplasticizer in the production of flowable concrete such as in:

Uses:

Slabs and foundations

Walls, columns and piers

Slender components with densely packed reinforcements

Precast and pre-stressed concrete elements

Bridges and cantilever structure

Advantages:

Workability is greatly improved

Increased placeability in slender components with packed

reinforcements

Decreases the amount of vibration

Normal set without retardation

Significantly reduces the risk of segregation

Water-reduction up to 30% depending on dosage

Allow substantial cement reduction compared to plain concrete

Product Da Ta

Liquid / Dark Brown

5 / 25 / 200 litres drum

Dry, cool, shaded place.

Min. 1 year if stored properly in original unopened packaging

Application:

.80 - 1.20 ltr. per 100kg of cement

Possible to combine with all Sikament, Sika Aer, Sika Pump, Sikacrete PP1, but must be added separately to the mix and not pre-mixed prior addition.

All Portland cement including sulfate resistant cement.

Sikament NN is either added to the gauging water prior to its addition to the dry concrete mix or added separately to wetted concrete mix, further mixing should take place for at least 1 minute per m .

When added directly to the freshly mixed concrete, the plasticizing effect is more pronounced.

For addition at job site, Sikament NN is added to the concrete immediately prior to discharge and after further mixing has taken place for three minutes.

Significant overdosage will result in a much increased flow of the cement paste and setting time of the concrete. To avoid bleeding or segregation it is recommended to wait until the slump has dropped to specified range prior to placement of concrete.

Typical mix design for grade 45 concrete on cube (at 28ºC)
