Product Description
JK-02NPis 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.
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
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. 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.
- Improve workability (slump) of concrete when added into mixing truck

Dosage
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.
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 result.
