Sikament® NN Powder

Water-Reducing Concrete Admixture

A highly effective superplasticizer for the production of free flowing concrete or as a substantial water-reducing agent for promoting high early and ultimate stregnth.

  • Complies with ASTM C-494 Type F

Sikament® NN Powder 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:
  • Up to 25% water reduction
  • 28-day strength improved by up to 40%

Usage

Sikament® NN Powder as a superplasticizer in the production of free-flowing concrete such as:
  • Slabs and foundations
  • Walls, columns, and piers
  • Slender components with densely packed reinforcements
  • Textured surface finishes
It is also used as a water-reducing agent leading to high early strength of concrete such as:
  • Precast concrete elements
  • Hollow blocks and pavements
  • Pre stressed concrete
  • Bridges and cantilever structures
  • Areas of concrete where formwork must be removed quickly or earlyloading applied

Application

Application Information

Dispensing

Sikament® NN Powder can added to the mixing water prior to its addition to the aggregates or as in most cases, it can be added directly to the freshly mixed concrete. When added directly to the freshly mixed concrete, the plasticizing effect is more pronounced. For ready-mix concrete, Sikament® NN Powder is added to the concrete immediately prior to discharge and after further mixing has taken place for three minutes.
Consumption

Recommended Dosage

(200 g) by 50 kg bag of cement. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. It is advisable to carry out trial mixes.
