SNF a high range water reducer, commonly referred to as a super plasticizer, also named Naphthalene Sulphonate Formaldehyde Condensate (short name: SNF, PNS, etc…)
SNF is made from naphthalene, sulfuric acid, formaldehyde and liquid alkali, through sulfonation, hydrolyzation, condensation and neutralization reaction and then drying to powder. SNF-A5% contains very small chloride. Thus, it meets the requirements of chemical admixture specifications for concrete: ASTM Designation C 494 as a Type F admixture, GB8076-2008 and GB50119-2003.

Packing: 25kg bag, 625kg bag, 650kg bag are available according to your requirement.

Shelf life: 12 months
SPEC:

Advantages: 

1. Substantial improvement in workability without increased water or the risk of segregation. Normal set without retardation, even when overdosed. Improved density and surface finish.

2. High water reducing rate, 40% increase in 28 days strength. High strength after 8 hours. 

3. Copatable with Portland cement, Normal portland cement, Pozzolanic cement etc. 

4. Improve workability (slump) of concrete when added into mixing truck. 

Dosage: 

0.5-1.5% by weight of cement. Exact dosage rates are depending on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature.  It can be added during mixing and after-mixing (better), The after-mixing approach can achieve better result.
