Water Reducer Sodium Naphthalene Formaldehyde NZY-FN China Manufacturer
Product Description
NZY-FN is a naphthalene-based highly effective water reducing admixtures for promoting accelerated early and ultimate
strength development, commonly referred to as a superplasticizer, also named Naphthalene Sulfonate Formaldehyde
Condensate (NSF), SNF, PNS and FDN etc.
NZY-FN contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable. It complies with
ASTM Designation C494, Type F, ASTM C 1017, GB8076-2008 and GB50119-2003 etc.
Product Uses
Produces the high slump flowing concrete with no loss in strength.
Produces low water/cement ratio concrete with high strengths.
Ideal for using in high strength concrete, flowing concrete, early strength concrete, precast steam curing concrete,
prestressed concrete etc. 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.
Be used as basic material to produce others compound admixtures, (such as accelerating and water-reducing admixture, retarding and water-reducing admixture, pumping antifreeze and pumping water-reducing admixture, etc.)
Advantages
Substantial improvement in workability without increased water or the risk of segregation. Normal set without retardation, even when overdosed. Improving density and surface finish.
High water reducing rate. 40% increase in 28 day strengths. High strengths after 8 hours.
Compatible with Portland cement, normal Portland cement, Portland Slag Cement, fly ash Cement, Pozzolanic Cement, etc.
Improving workability (slump) of concrete when added into mixing truck.

Dosage
0.5--1.5% by weight of cement. Exact dosage rates depends on the type of effect sought,quality of cement and aggregates,
water/cement ratio and ambient temperature. Therefore in many cases it is advisable to carry out trial mix.
NZY-FN can be added directly or added in after dissolved in water. It can be added during mixing and after-mixing(better). The
after-mixing approach can achieve better results.
Packaging, transport and storage
1. The powder product is packed with 25 ± 0.25kg laminating woven bag. Packaging specifications should meet the user
requirements.
2. Powder product is easy to soluble in water, liquid dilution will affect the effective concentration of the product, transport and
storage should be noted that the anti-leaching, avoid moisture, direct sunlight, kept under seal and away from open flame at
the room temperature or during the transport.
3. In the case of good storage conditions, valid period is three years. If it is more than 3 years, rechecking is needed for using
continually.
