Sikament® NN

High Range Water Reducer / Superplasticiser Admixture For Concrete

Sikament® NN is a highly effective admixture for concrete especially suitable for the production o ff dual action liquid superplasticiser for the production of free flowing concrete and for the production of high strength concrete, especcially in hot climatic conditions.

As Superplasticizer
  • Improved workability 
  • Improves concrete placement
  • Especially suitable for slender components with congested reinforcement
  • Improved compacting behaviour
  • Improves cohesion of the concrete mix which significantly reduces the risk of segregation
  As high range water-reducer
  • Up to 25% of water reduction.
  • Pronounced increase of final strength.
  • 16 hours compressive strenghth increased by up to 100%(depende on dosage).
  • Reduced permeability for water.

      Technical Information

      Concreting guidance

      The standard rules of good concreting practice, concerning production and placing must be followed.
      Laboratory trials must be carried out before concreting on site, especially when using a new mix design or producing new concrete components.
      Fresh concrete must be cured properly and curing applied as early as possible.

      Application

      Application Information

      Dispensing

      Sikament® NN must be measured using suitable equipment then added to the batching gauging water or both added together at the same time into the  batching plant concrete mixer.

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

      Compatibility

      Sikament® NN may be combined with many other Sika products. Trials must always be carried out before combining products in specific
      mixes.
      Consumption

      Recommended dosage

      0.5 - 3% 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.
      Application steps

      CLEANING OF EQUIPMENT

      Clean all tools and application equipment with water immediately after use.
