High Range Water Reducing Concrete Admixture Sodium Naphthalene Sulfonate

High Range Water Reducing Concrete Admixture
Naphthalene Superplasticizer ASTM C494, Type F
JK-02NPSodium Naphthalene Sulfonate(Na2SO4≤18%)DescriptionJK-02NPis anaphthalene-based highly effective water reducing agent for promoting accelerated early and ultimate strength development, commonly referred to as asuperplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate ), SNF, PNS and FDN 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 aminimum 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. High strengths after 8hours.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.

Dosage0.5 -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-02NPcan 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.Package, Storage &Shelf LifeFor powder: Powder packed in 650kg jumbobag.
It should be stored in adedicated warehouse that is well-ventilated and dry and keepaway from moisture.
Shelf Life: Minimum24months. After the expiration date, it can be used if testing results is qualified.
