Naphthalene Sulfonate Formaldehyde / Poly Naphthalene Sulfonate (SNF/NSF/PNS)
Naphthalene Sulfonate Formaldehyde (NSF) is a naphthalene-based Superplasticizer a chloride-free admixture which is
supplied as a brown powder to be instantly dissolved in water. This concrete admixture is used to affect substantial water
reduction to concrete without influencing normal setting time and further improves the durability, workability, and strength
of concrete.Poly Naphthalene Sulfonate Formaldehyde (SNF/NSF /PNS) complies with the requirements of the following
standards: ASTM C 494, Type F; ASTM C 1017
|Appearance||Light brown powder||Light brown powder||Light brown powder|
|Sodium sulphate Content||5%||10%||20%|
|Net Starch Fluidity||≥250 mm||≥240 mm||≥230 mm|
3. SNF USAGE:
A. Blending dosage at 0.5%-1.0%, 0.6% mixing dosage advised.
B. Prepare solutions as required.
C. Direct use of powder agent is allowed. Alternatively the addition of the agent is followed by water moisturization
4. SNF Package
25kgs/Bag or Ton bag,16Tons/20'gp
5. SNF Application
---To provide initial workability especially with low water cement ratio.
---To significantly improve the initial workability of site mixed concrete without increasing water demand.
---To provide improved durability by increasing ultimate strengths and reducing concrete permeability.
---To have high slump retention with early setting time.
Sulfonated Naphthalene Formaldehyde is used as a super-plasticizer 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 concrete such as:
---Pre-cast concrete elements
---Bridges and cantilever structures
---Areas of concrete where formwork must be removed quickly or early loading applied
