Sikament® NNG

Superplasticizer / High range water-reducer and Retarding admixture

Sikament® NNG is a highly effective admixture for concrete especially suitable for the production of free flowing concrete and for the production of high strengths concrete, especially in hot climatic conditions.

Sikament® NNG provides the following properties:
As superplasticizer
  • Workability is greatly improved.
  • Increase place ability in slender components with densely packed reinforcement.
  • Enables easy placing, less vibration needed.
  • Good slump keeping effect.
As high range water-reducer
  • Up to 25% of water reduction.
  • Pronounced increase of final strengths.
  • Reduced permeability for water.

Usage

Sikament® NNG acting as superplasticizer or as high range water-reducer and retarder, promotes a very high plasticity and good slump keeping properties to concrete.
Sikament® NNG is mainly used for the following applications:
  • Concrete with strong fluidity.
  • High quality concrete.
  • Concrete applied in precast.
  • Concrete submitted to long transportation, delayed placing and high temperatures.  
  • Concrete with high water reduction while maintaining favourable consistency enabling good early strength development.

Application

Application Information

Dispensing

Sikament® NNG is added to the gauging water or can be added separately to the freshly mixed concrete (the plasticizing effect is more pronounced). Never add Sikament® NNG directly to dry cement or aggregates (will cause efficiency reduction)


Sikament® NNG can also be added to the concrete immediately prior to discharge and after further mixing has taken place for at least three more minutes.
Consumption

Recommended dosage

0.5 – 3.0 % by weight of cement, depending on the requested performance of the concrete.

It is advisable to carry out trial mixes to establish the exact dosage rate required
