Uses

Poly Naphthalene Sulfonate Formaldehyde produces concrete with extremely workable characteristics referred to as 



high slump. PNS also allows concrete to be produced with very low water/cement ratios at low or normal slumps.

Poly Naphthalene Sulfonate Formaldehyde is ideal for use in prestress, precast, bridge deck or any concrete where 



it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to 



provide easy placement and consolidation.





Addition Rates

Poly Naphthalene Sulfonate Formaldehyde can be added directly or added in after melt. It can be added during mixing 



and after-mixing. The afterward approach can achieve better result. The suggested addition rate is 0.*5%.





Poly Naphthalene Sulfonate Formaldehyde Direction

Prepare solutions as required.

Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization 



(water-cement ratio: *0%).

The agent can be combined with other externally applied agents if pilot development or laboratory experiment 



succeeds.



Packing of Poly Naphthalene Sulfonate Formaldehyde:

Packed in plastic film bag wrapped with plastic woven sack with a net weight of *5kg each.
