Sikament® NNG

SUPERPLASTICIZER / HIGH RANGE WATER-REDUCER

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
  • Pronounced increase of final strengths.
  • Reduced permeability for water.

Usage

Sikament® NNG acting as superplasticizer or as high range water-reducer, 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 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. In this case, further mixing should take place for at least one minute per cubic meter.


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

0.4 – 3.0 % by weight of cement, depending on the requested performance of the concrete.

Usual dosage : 0.5 - 2.0 % by weight of cement.

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

APPLICATION INSTRUCTIONS

Sikament® NNG allows the production of high performance concrete, as long as the composition is well design and standard rules of good concreting practice are followed (production as well as placing).
Fresh concrete must be cured properly and as early as possible especially in hot climatic conditions in order to prevent plastic and drying shrinkage.

  • We recommend previous tests to determine the correct dosage of the admixture and whenever concrete composition is changed.
  • When accidental overdosing occurs, the set retarding effect increases. During this period the concrete must be kept moist in order to prevent premature drying out.
  • For further details contact our Technical Department.
