Naphthalene Formaldehyde Sulphonate Water Reducing Agent (NFS)

Naphthalene Formaldehyde Sulphonate Water Reducing Agent (NFS)
Product Detailed
1.high range water reduction, 2.set-retarding and excellent strengthening.


EK601 naphthalene formaldehyde sulphonate water reducing agent is a synthetic powder based on beta-sulphonate formaldehyde condensate and reactive polymer. It has the properties of high range water reduction, set-retarding and excellent strengthening. EK601 is suitable to middle-strength or high-strength concrete where high range water reduction and set-retarding is desired.

Features and Benefits:

High water reduction: Water reduction rate can be above 20-40%.High strengthening effect: Compared with ordinary concrete, the strength of concrete with EK601 at the age of 28 days can be improved by 35~60%, at the age of 90 days can be improved by 20%.Outstanding set-retarding: it can retard the initial and final set time by range of 6-20 hours. The specific set time can be modified according to the site requirement.Good workability: It can provide high slump-retaining and very low slump loss effects. EK601 improves workability and pumpability with no bleeding and segregation.Low hydration heat: Compound with those if pure cement paste, the time when peak of hydration heat appears is delayed by 24 hours. Moreover, the hydration heat of paste at third-day age is only 1/5 of that of pure paste.Wide compatibility: EK601 is adaptable to different types of cement and other admixtures such as air-entraining agent, retarder.Excellent durability: EK601 can effectively improve the durability of concrete, such as carbonization resistance and freeze-thaw resistance.Convenience for use: It can be added directly into concrete or dissolved beforehand into liquid state. It matches the requirements of different application conditions or mixer types.


Addition rate: The normal range of EK601 added rate is 0.4~0.6% by weight of cementitious materials. The added amount depends on the required degree of retardation under job conditions. Longer setting time or higher ambient temperature requires higher addition rates and conversely the addition rate will be lower than normal.


EK601 is packed in the waterproofing double-layer plastic bag and the net weight is 25Kg per bag.
