Sikament® NN

High range water-reducing concrete admixture

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 provides the following properties:
As a superplasticizer:
  • 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
As a water-reducer:
  • Allow substantial cement reduction compared to plain concrete

Usage

Sikament® NN is used as a superplasticizer in the production of flowable concrete such as in:
  • Slabs and foundations
  • Walls, columns and piers
  • Slender components with densely packed reinforcements
Sikament® NN is also used as a water-reducing agent leading to high early strength concrete such as:
  • Precast and pre-stressed concrete elements
  • Bridges and cantilever structure

Application

Application Information

Compatibility

Possible to combine with all Sikament®, Sika® Aer, Sika® Pump, Sikacrete®
PP-1, but must be added separately to the mix and not pre-mixed prior
addition.
Cement types: All Portland cement including sulfate resistant cement

DISPENSING

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 m3.
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.
Consumption

Recommended Dosage

Dosage: 0.60 – 2.00 ltr per 100 kg of cement
Typical dosage: 0.80 - 1.20 ltr. per 100kg of cement
