description:
Naphthalene
formaldehyde sulphonate water reducing agent is a synthetic powder
based onbeta-sulphonate formaldehyde ondensate and reactive
polymer.
It has the properties of high range water reduction, set retarding and excellent strengthening.
Elt-nsf
sodium sulfate is less than *0% , suitable to middle strength or
high strength concrete where high range
water reduction is desired.
Â
Application:
1.Produces the high slump flowing concrete with no
loss in strength.
2.Produces low water/cement ratio concrete with high strengths.
3.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.
4.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.)

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.
SNF-C 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.
For powder: Woven plastic bag with film liner. Net weight: *5kg +/- 0.2 kg.
It should be stored in a dedicated warehouse that is well-ventilated and dry and keep away from moisture.
Shelf Life: Minimum *2 months. After the expiration date, it can be used if testing results is qualified.
