High Range Water-Reducing Admixture
Sodium Naphthalene Sulphonate Formaldehyde, Poly Naphthalene Sulfonate Formaldehyde Condensate,Concrete Admixture
Naphthalene Sulfonate Formaldehyde Uses
Sodium Naphthalene Sulphonate 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.
Sodium Naphthalene Sulphonate 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
Sodium Naphthalene Sulphonate 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 0.75%.
Sodium Naphthalene Sulphonate 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: 60%).
The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.
Notices:
1.Before use, mix ratio test must be done,especially for the first time using this product, to find out the correct mix rate and dosage.
2.High grading cement and reasonable sand/stone grading must be used to make high-strength or super high-strength concrete.
3.Water dosage must be strictly controlled to keep mixture unchanged.
4.The mix time should be prolonged for one minute;care should be taken to strengthen wet curing.
5.If used with liquid form , moisture should be deducted from concrete mixture.
