Description

JK-02NP Sodium Naphthalene Sulfonate Formaldehyde(Na2SO4<=18%)

JK-02NPis anaphthalene-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.

JK-02NP 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.

Advantages

  • 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, Pozzolanic Cement, etc.
  • Improve 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 mixes.
JK-02NP 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.
