Product Description High Range Water Reducing Concrete
AdmixtureNaphthalene Superplasticizer ASTM C494, Type FJK-SNF-A
Sodium Naphthalene Sulfonate Formaldehyde
(Na2SO4≤5%)JK-SNF-A is 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-SNF-A possesses the features of no
retarding, no air-introducing, superplastic high water-reducing and
strength enhancing. It has no chloride, low alkali content, low
sulphonate, and high purity. It can be widely used in different
concretes with less dosage and easy to use.JK-SNF-A can be applied
to make flowing, strong or steam-curing concrete. The minimum
working temperature can be as low as 0ºCdegrees. In steam curing,
concrete with superplasticizer has to be strong enough before
heating. The steam curing specification has to be pre-tested. It is
particularly used as base material for compound
admixtures.ApplicationProduces 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.) Substantial improvement in
work-ability 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 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. SpecificationItemsCriteriaActual

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-SNF-A 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.Packing and StorageFor powder: Powder packed in 25kg bag or
650kg jumbo bag.It should be stored in a dedicated warehouse that
is well-ventilated and dry and keep away from
moisture. Shelf Life: Minimum 12 months. After the expiration
date, it can be used if testing results is qualified. Sample
