Product Description:

SNF High Water Reducing Type from CNBM China with More than 10 Years' Experience


Product Description

NZY-FN1is a naphthalene-based highly effective water reducing agent 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-FN1 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

  • Producing the high slump flowing concrete with no loss in strength.

  • Producing  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.)



  • Substantial improvement in workability without increased water or the risk of segregation. Normal set without      retardation, even when overdosed. Improved 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, Flyash Cement, Portland Pozzolanic Cement, etc.

  • Improving workability (slump) of concrete when added into mixing truck.

0.5 – 1.5% by weight of cement. Exact dosage rates are dependent 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 mixes.

NZY-FN1 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 result.
